Top 10 Vocaloids with the Best Voices

Generally, people appreciate a Vocaloid's character design more than the voice itself. But could you cast your vote considering only the Vocaloid's voice? Some Vocaloids have voices that are significantly better than Hatsune Miku's!

Let's demonstrate that character design isn't the most important aspect here. Vocaloid is ultimately about the music, not just appealing designs. Let's focus on that.

The Top Ten

Megpoid (GUMI)

Megpoid is a Vocaloid voicebank developed by Internet Co., Ltd. The voice was sampled from Japanese voice actress and singer Megumi Nakajima.
The mascot character for the software is named Gumi, which comes from Nakajima's childhood nickname. Megpoid has been widely used in various music productions... read more

I don't hate GUMI, but I dislike how you guys judge a Vocaloid's voice by its realism. Just because it's realistic doesn't mean it sounds the best. I'd rate her as 8/10, actually. Her voice isn't particularly interesting, but I still like her. Yes, she does have the most realistic Vocaloid voice, but if you want realistic voices, you can just listen to real humans. They sing better too. Don't tell me they're autotuned and stuff, because there are still singers that don't use autotune.
Back to the topic, some of GUMI's songs are pretty good too, like ECHO. GUMI can sound good even with a robotic voice.

I sometimes think, "Why do people often love Miku or Rin/Len best, and not GUMI, Luka, Yukari, or others?" Yes, many people love Miku because she's beautiful, has many appends, and has various characters (Snow Miku, Sakura Miku, Racing Miku, etc.). But other Vocaloids don't have that luck. Miku is always the most popular. How sad for the others.
When I became a fan of Vocaloid, I didn't know which Vocaloid I would be a fan of. But after hearing many of GUMI's songs, I think I love GUMI. Maybe GUMI doesn't appear with the most beautiful appearance or as many appends as Miku, but to me, GUMI always shines. She is always my BEST IDOL! Love you, GUMI!
Kagamine Rin

Kagamine Rin and Len are vocal synthesizer characters developed by Crypton Future Media, which is based in Sapporo, Japan. They are part of the Vocaloid series, a voice synthesizer software used to produce singing by inputting lyrics and melody. The characters have gained popularity worldwide for their... read more

In Kokoro, she sounds like a robotic angel. In Paper Planes, she sounds like a young human girl. In Daughter of Evil, she sounds like an evil princess. Rin can have a human's voice, a robot's voice, or an angel's voice. And those are just the ones we have heard!
Her and Len's songs can make a grown man cry when they die. Their voices can portray so many emotions. They don't sound like angels, they ARE angels. Anyone who disagrees, well, they are crazed. Rin is the best Vocaloid that will ever exist!

I love her voice! Gumi is my next favorite, but she only has one tone of voice that sounds appealing, while Rin's voice varies and sounds amazing almost always! Ever since I saw Rin and Len, I threw away Miku and started appreciating them.
The reason I voted for Rin was to get one of them to the top, but Len has a similar variety to his voice. Rin is like a Miku but better! She was made to overthrow her, so of course, she has a great voice! She deserves to be on the top of this list!
Kagamine Len

Kagamine Len is a male Vocaloid developed by Crypton Future Media and voiced by Asami Shimoda. He was released along with Kagamine Rin on December 27, 2007, as part of the Vocaloid2 series.
The character has received multiple updates, including Act 2 in 2008, the Append version in 2010, and the... read more

Len should get more love. His voice has pure and super understandable vowels and consonants, like Rin, but he also has a very soothing tone to his voice (that's just my opinion).
Anyway, if you have anything bad to say about Len or any of the Vocaloids, let me say one thing: the quality of most of the voices depends on whether you can use them correctly and know how to tune their voices to make them sound better. I mean, take the append versions of Servant of Evil and Daughter of Evil, aka the Project Mirai versions. When I first listened to these, I had a hard time believing that they were singing! So, this confirms that both the Kagamines, especially Len, need more love!
Oh, and if you're a fangirl of Len, please share this with other girls who are also fans of Len because I know he has A LOT more fans out there. PS: When I posted this, he was at number five.
IA

IA is a humanoid character voiced by a singing synthesizer application developed by 1st Place Co., Ltd., based in Meguro, Japan. The software uses Yamaha Corporation's Vocaloid 3 singing synthesizer technology. Her voice is sampled from Japanese singer Lia, and IA has been featured in numerous music... read more

IA is my only favorite Vocaloid because she has the most unique and realistic voice. Her image is also very different and catchy. Look at her innocent face. She is so cute! And her dress? It's so futuristic. Plus, her silver Rapunzel-like hair and galaxy eyes are unique to her. When compared to others, her movement is incredibly smooth. They look like robots when they dance.
IA is extraordinary and deserves to be in the top ten. She's new but has already become popular, showing that many people love her voice. IA is awesome. When I listen to her voice, I feel like I am floating because of its power.
Megurine Luka

Megurine Luka is a humanoid character voiced by a singing synthesizer application developed by Crypton Future Media. The company is headquartered in Sapporo, Japan. Luka was released as part of the Vocaloid 2 engine and is known for her bilingual singing capabilities in both Japanese and English.

Megurine Luka has been a part of my life for a very long time. I started listening to Vocaloid when I was in 6th grade. At that time, I was going through severe depression and anxiety, and Luka helped with that. When I listen to most Vocaloid songs, they give me a headache or they are just too loud and squeaky. However, I have an entire playlist of Luka songs on YouTube. The playlist is called "Soothe Sounds." I named it that because of her soothing voice, which actually helped me sleep every night.
Luka's songs have nice sounds and peaceful tuning. The lyrics give me hope and inspire me to look forward to another good day. Now, in my first year of high school, I listen to her every day for inspiration. The song "No Logic" really makes me see that the world can be confusing at times, but there is always a way to go when you feel sad or down.
When I hear Gumi or even the Kagamine twins sing, it's always depressing and dark, which doesn't help at all. The high-pitched noises make me feel very uncomfortable because they blast through my eardrums and make my chest hurt. Megurine Luka, with her powerful voice, has helped heal me from depression up until this day.
Hatsune Miku

Hatsune Miku, sometimes referred to as Miku Hatsune, is a humanoid persona voiced by a singing synthesizer application developed by Crypton Future Media. She is part of the Vocaloid software series and uses Yamaha Corporation's Vocaloid technology. Miku has become a global virtual pop icon, performing... read more

Hatsune Miku represents what Vocaloid is and embodies as a whole. She may be the most popular Vocaloid character, but she definitely deserves it. Her range is incredible, her voice is perfect, and her songs are meaningful.
People don't vote for her just because she's attractive or whatever. (Honestly, I think Len's voice is quite nasally. Don't kill me.) They vote for her because she has defied being just a computer program or a synthesized voice. She is an idol.

I'm not being a blind Hatsune Miku lover here. I am saying Miku because of her voice quality. Unlike many Vocaloids, her pronunciation is clear and crisp. I'm not saying the ones that aren't clear are bad. For example, Gumi isn't always clear, but has an amazing voice. Her voice can handle many styles and pitches, and her songs come out beautifully.
Many other Vocaloids that people compare to Miku may have a thicker or more beautiful voice, but they cannot compete with her voice quality. When she sings "mazeawasete, mazeawasete", it sounds exactly like that. It doesn't sound like a mess of kind-of-like-that syllables. I'm looking at you, Rin and Len.
I'm not bashing other Vocaloids. I love all of them. Well, except Kaito on fast high songs. I honestly believe that Hatsune Miku has a beautiful voice.
Gackpoid (Kamui Gakupo)

Hatsune Miku was the first Vocaloid I heard, but she isn't the one who tempted me to enter the world of Vocaloid fandom. That honor goes to Gackpoid.
He's very difficult to tune, to be honest. His songs often sound choppy and muffled, among other things. But from his voice, I can hear quality and a unique, manly characteristic that most other male Vocaloids don't possess. Well, what can you expect less from GACKT?
I see that most people prefer KAITO and Len over other male Vocaloids, including Gaku, probably because of Crypton's marketing and the fact that their designs are way cooler than Gaku's.
But, in my opinion, their voice quality cannot beat Gakupo's. Overall, yes, Gakupo may be beaten by character design, but it's undeniable that he has the best voice quality of all male Vocaloids.
KAITO

KAITO is a humanoid persona voiced by a singing synthesizer application developed by Yamaha Corporation using their Vocaloid singing synthesizer technology under the codename "Taro." Released in 2006, KAITO was one of the first Japanese Vocaloid voicebanks. He has since gained a strong following and... read more

With a range of nearly 5 octaves and a voice extremely sensitive to parameter changes, KAITO V1 is a voice to be reckoned with. His V3 is less strong in these regards, but still features an all-around vocal that many non-Vocaloid fans I know have described as 'beautiful, warm, and pleasant', so he certainly draws attention still. I think he should be recognized a little more for his capacities overall!

KAITO was the first Vocaloid I listened to, and he's still my favorite.
A lot of people complain that his voice is too boring, but I think his voice is so beautiful. I love the messages behind his songs.
Yuzuki Yukari

Yuzuki Yukari (結月ゆかり) is a Japanese VOCALOID developed by Vocalomakets and distributed by AH-Software Co. Ltd. She was first released in December 2011 for the VOCALOID3 engine and is also available as a VOICEROID+. In March 2015, she was updated for the VOCALOID4 engine with the addition of two more... read more

I absolutely love Yuzuki-san, especially when she sings with Luka in Resurrection Trip, or MAYU in Hurting for a Very Hurtful Pain. Whatever the song, I love her vocal range and style. I can't believe some people say her breathy and raspy-like voice is horrible. They're just too busy obsessing over Miku-chan and Luka-san.
Open your eyes. There are many more Vocaloids with unique voices and designs. You've just got to take the time and patience to listen to them.

Yukari's voice is really realistic, and some people say that her breathy voice is horrible. But honestly, I see her breathy voice as a strength because when it fades out, it adds some sort of emotional effect and gives you the chills.
MEIKO

MEIKO is a humanoid persona featured in a voice synthesizer application developed by Yamaha Corporation using the Vocaloid engine. She was the first Japanese Vocaloid voicebank released by Crypton Future Media. MEIKO's voice is provided by a female Japanese singer and has been used in numerous original... read more

She is amazing if done right. She has an epic voice that can be adapted to any music, and she is just so unique, not being one of those sopranos all the time. Her English is one of the most realistic and understandable. Her power has so much emotion and realism, and her vocal range can adapt to any song, from pop to jazz or rock, at any time.
Meiko Haigo, her voice provider, sounds like Meiko, even though she is the first Japanese Vocaloid. Haigo's personality is really sweet, and she even looks like Meiko, which is evident in the name. This shows how much care went into her design, but some people just ignore the effort and dislike it.

She's like a robotic angel. People look down on her because she sounds too robotic, but isn't that the point of Vocaloid? If you wanted something realistic, why are you listening to Vocaloid?
MEIKO's voice is perfect because you can do literally anything with it. She can be a psychopathic Yandere, a sweet DereDere girl, a rough and intimidating delinquent, a mother, or even just a normal girl. Hatsune Miku, no matter how much I love her, cannot do that.

The Newcomers

?
MEIKA Mikoto

Their voice is so powerful, and their low range is just chef's kiss.
?
MEIKA Hime

She has a sweet voice just like Miku's voice. I wish she were one of the most famous.

Their voice is so soft and cute. I love it!

The Contenders

Utatane Piko

Utatane Piko is a Japanese Vocaloid developed by Sony Entertainment for the Vocaloid 2 engine. His voice is based on the Japanese singer Piko. Utatane Piko was released in December 2010 and was designed to offer a realistic male vocal.

It's a shame not many people know Piko. I've loved his voice since I first heard of him. My favorite song has got to be his original song, "Remember."
Try listening to his cover of "Ura-Omote Lovers," and you'll fall head over heels in love with his voice. And once again, Miku is number one... Sometimes I just don't get you people.
And will everyone stop with the 'this Vocaloid sounds like this one plus this one'? I'm sick of it, I tell you.

I feel so trolled by Piko. Why? That awkward moment when a boy sings better as a female than you. I just can't stop laughing when people mention the "Boku no Piko" joke! Utatane Piko, your voice is amazing, even if you share voices with the Nico Nico Singer Piko.
I look at Piko as more of a shota than Len and Oliver. But when he sings "Spice," Piko is bringing sexy back.
OLIVER

Oliver is an English-language Vocaloid developed by PowerFX Systems AB in collaboration with VocaTone. His voice was recorded from a British choirboy and he was released for the Vocaloid 3 engine in December 2011. Oliver is popular for his youthful and classical vocal tone.

Oliver is my favorite male Vocaloid, simply because of his unique voice quality.
Having been voiced by an English choir boy, he has an incredible range that older voices simply cannot achieve. Therefore, he gives writers a rare opportunity to work with a pure and angelic-sounding voice.
Interestingly, the 'angelic' connotations of his choir boy voice allow Oliver to fit into both innocent and soft music as well as dark and haunting music. The only way I can think of to describe how it works is by using the example of nursery rhymes. They sound cheerful when you sing them like you did on the playground, but they sound terrifying once you slow them down or learn about their origins. (Just look at Ring-a-ring-a-roses!)
But I digress...
I also find Oliver easy to work with, but that is probably largely due to the fact that he is from my country and speaks my language. I found him easier to work with than, say, Megpoid, well, until she had an English voice bank anyway.
In any case, I think he deserves more recognition.
VY1

Did you hear her V4 voice? It's brilliant. VY1 has one of the most amazing voices in Vocaloid. I love how her voice is so mature, similar to others such as Gumi, IA, or Yuzuki Yukari. She is just so great at singing, and it's so sad how she is not recognized by the fandom as much as other Vocaloids have. I'm not saying that the others are worse or bad, I'm just pointing out that there are many unrecognized Vocaloids who sing just as well or even better than the main and more popular Vocaloids.
VY1 is an amazing Vocaloid with an amazing voice. If you haven't yet listened to her voice, you should. It is worth the time. If you already have, keep up the good work and spread the love for all the less popular Vocaloids!
Nekomura Iroha

Iroha Nekomura is a female Vocaloid voicebank developed by AH-Software Co. Ltd for the Vocaloid 2 engine. Her voice was provided by the Japanese singer Kyounosuke Yoshitate. Released on October 22, 2010, Iroha is often visually represented with cat-themed features and a futuristic aesthetic.

Her voice is like all the most beautiful voices mixed together! So amazingly realistic. Her low vocal range can still remain young and sound mature.
It's such a pleasure to hear her sing. I always forget that she's a Vocaloid. Usually, I end up going for the Nico Nico chorus of other Vocaloids, but I always listen to the original of Iroha's because she is just that awesome.

I think Iroha Nekomura deserves to be more popular. Okay, she has a low voice, but listen to her voice carefully, and you'll discover that it actually sounds more mature and realistic than most. The first time I listened to her songs, I was in love! She won me over with her mature and steady voice.
Kaai Yuki

Kaai Yuki is a child Vocaloid character produced by AH-Software Co. Ltd and released originally for Vocaloid 2. Her voice is provided by a real elementary school student, making her one of the few Vocaloids with a child's voice. Kaai Yuki was released on December 4, 2009.

Even though she is voiced by a kid, and her mascot is a kid, Yuki can sound pretty mature. Check out "Inaba Cumori". They use her so well. However, there are some songs that don't use her voice too well.
"Shooting Star" is just not a good usage of her voice. I am also not a fan of her V2. On the other hand, V4 is so well thought out.

Her voice really fits her design, so cute. She has a really cute, relaxing, soft voice, and because of it, the first time I listened to her, I already fell in love with her, and she became my favorite Vocaloid.
She has a really cute voice when singing English and Japanese. She's too underrated, though. I wish she was one of the top ones.
v flower

Honestly, her voice is very nice. People mainly look towards the more "popular" Vocaloids, or maybe because they just sound more realistic. I just adore the way her voice sounds. The metallic ring in her tone isn't too much, nor too little.
Her emotion is something that the listener can really gauge when listening to her music, even if she isn't an actual human being. That's what I love about her. The fact that she's in #20 is very disappointing, especially when I see the more popularly known Vocaloids. Flower deserves more love, guys. Come on!

Just listen to their cover of "Mind Brand" if you want proof of their amazing voice. I love that they can convincingly sound like a guy or a girl, giving their voice a lot of potential. That potential has gone unused, as I think they only have one original song (Inokori Sensei, their release song).
They're a refreshing change from the typical Miku-esque Vocaloids we've gotten used to, and I'm thankful for that.
VY2

People dislike him because he can sound drunk. Even I thought that when I first listened to him. But now, I see him as very natural.
I mean, come on, not every VOCALOID is going to be perfect. Yuuma is far from it! But I find his voice very endearing, and I think you might, too, if you listen carefully.

His voice is so unique compared to the other male Vocaloids. Even though there are a few problems with his voice bank, it still ranks as one of the better ones, in my opinion. His range is better than most other males, seeing as he was created to be gender-neutral, but he sounds better with lower vocals.
SeeU

SeeU (Korean: 시유. RR: Siyu) is a female Korean vocal created for the Vocaloid 3 software by SBS A&T (formerly SBS Artech) and was the only Korean vocal released for that version of the software. As well as a Korean vocal, she possessed a Japanese vocal. The voice behind her is Dahee Kim from the former... read more

I don't really like Vocaloids to begin with, and I don't have any of the actual software. However, I do like SeeU a lot. Her voice is beautiful and rather calm, unlike Miku, who tends to make my ears bleed. No one can sing that high-pitched in real life.
I also like her design. She is very cute and has actually normal-colored hair, unlike most of them. Miku should really just be taken down so some of the less popular Vocaloids can have a chance at being a pop star like Miku. She also is not completely self-absorbed like Miku and Kaito.

Her voice and style seem very lovely. She has different tones to her voice. Moreover, it is lingering and mature.
Although I am not much of a Vocaloid fan (heck, I barely know ten of them), she is the one I like. As many before have said, Miku's voice is very simple. I still enjoy quite a few of her songs.
Otomachi Una

Otomachi Una, sometimes referred to as Una Otomachi, is a female Vocaloid developed by Internet Co., Ltd. and MTK Inc. She is voiced by voice actress Aimi Tanaka, who also provides vocals for various anime and game characters. Otomachi Una was released in 2016 and is known for her energetic character... read more

Otomachi Una has a vocal range like no other. She works in heavy songs, light songs, and even just talking! Seriously, listen to that cover of MELT. It's never the same.

Her voice is good. She has an amazing talking voice and probably the most creative design. I mean, who else has a jellyfish hat?

Ooh! Love her! Her voice is so cute! She is like a way more high-quality Miku who is way more adorable and better sounding.
SF-A2 miki

SF-A2 codename Miki is a female Vocaloid character produced by AH-Software Co. Ltd for the Vocaloid 2 engine. She was released in October 2008 and features a Japanese female voicebank. Miki is often used in Vocaloid music and illustrations and remains a recognized figure in the Vocaloid community.

Yes! Miki sounds so adorable! You barely see anyone using her, though. She's one of my favorite Vocaloids! I'm so happy that she's getting a V4 because then, hopefully, people will start using her more and appreciate her beautiful voice!

I feel so bad for Miki. She is really underrated and not well-known. If we could start all Vocaloid engines over, put Miki in the first engine so she gets noticed!

Miki is the first Vocaloid I have ever listened to, and honestly, I think she is much better than Hatsune Miku, and she needs more attention!
Fukase

Fukase is a vocal developed and distributed by Yamaha Corporation for Vocaloid 4. He is voiced by Satoshi Fukase, the lead singer of the Japanese band SEKAI NO OWARI. Released in 2016, Fukase's voicebank supports both Japanese and English, and he is known for his distinctive vocal tone.

I just love Fukase. Whether it's appearance or voice, they are the best among the male Vocaloids. He's new, so people don't know him well, but I hope that people and Vocaloid fans discover him.
His voice is not too high and not too low. It's perfect. He also sang in English more fluently than other Vocaloids because his voice provider is Fukase from Sekai No Owari. His appearance looks like a mix between reality and fantasy.
He took first place on my list of favorite male Vocaloids. He is the only Vocaloid whose voice I like. No offense to Len, KAITO, Gackpoid, and the others.

He's one of the newer Vocaloids, but dude, does he have a good voice! Not too dark and not too high-pitched. His design is really good, too, and the fact that both his English and Japanese voicebanks sound good makes it all better. My favourite male Vocaloid, easily!
Luo Tianyi

Luo Tianyi is a Chinese Vocaloid virtual singer first released on July 12, 2012. She was originally developed by Bplats, Inc. and is now managed by Shanghai Henian. Luo Tianyi has gained widespread popularity in China, performing in live holographic concerts and appearing in various multimedia projects... read more

I was going to vote for Gumi or IA. I admit it, but seeing Luo all the way down at #22 made me really sad. Her voice is very realistic, and she speaks Chinese and Japanese!
Please consider listening to her songs, even though she isn't as popular as Miku or Rin. Not to mention, her character design is as flawless as her voice.

Luo Tianyi's voice is literally amazing! People should choose wisely and not just choose the popular ones! Oh right... It's all about Hatsune Miku now...

Some very good songs. Unfortunately, the Chinese Vocaloids aren't as well-known as Japan's.
YOHIOloid

Yohioloid is an English Vocaloid developed by PowerFX who also has an additional Japanese voice bank. The vocalist sampled for his vocals was Swedish singer Yohio. Released in 2013, Yohioloid is known for his visual kei-inspired character design and versatile voice.

He has a very unique voice in many types of songs. For example, in "The Chattering Lack of Common Sense," his voice is middle-ranged, and in other songs, he has either a higher or lower voice. I like it. If I had to pick a ship, it'd be a strange but cute ship. My YOHIOloid ship is YOHIOloid x Len. It sounds adorable and sweet. I think he deserves more love than Megurine Luka sometimes. No joke. I love YOHIOloid so much. He will always be my English baby boi! For the road, ship YOHIOloid x Len!

YOHIOloid is one of the first English Vocaloids that is hard to distinguish from a real person. Most other English Vocaloids sound robotic. This one sounds slightly robotic, but with the right tuning, he sounds human.
Lily

Lily (Japanese: リリィ, Riryi) is a female Vocaloid created by Internet Co., Ltd., in collaboration with Avex Management Co., Ltd., and Yamaha Corporation. She was initially released in August 2010 for the VOCALOID2 engine.
A second installment, developed for the VOCALOID3 engine and named V3 Lily... read more

Lily's voice is very unique. It's very low and more human. Despite her accent, her English is very easy to understand. I love her. In fact, she was the first Vocaloid I ever had. My favorite song from her is Lilyzm Gold, but there is also a version of Blood Teller that everyone should look into!

When used right, Lily is just AMAZING. Sadly, her demo song did not show her full potential. I love Sky is the Limit, Reminiscence of Garnet, Niki songs, and so many more. She sounds very realistic, and she speaks well in English as well.
Aoki Lapis

Lapis doesn't seem to be very popular with the fans, at least the ones I've seen, which I guess is fair, considering that she's a newer Vocaloid. Since she's newer and a Vocaloid 3, she gets some of those perks, like a more realistic voice.
She doesn't seem to be the best for songs like, say, iNSaNiTY. But personally, I like her cover of Love is War more than the original.

If everyone likes Miku, Rin, and Luka, why don't they love Lapis? She has a Rin-like brightness with Miku's sweetness and Luka's consonants and amazing realness. She's a V3, which makes her quality extraordinary! I love how she covers most songs. For me, she just needs more attention.
