As a Korean who also speaks Japanese, it sounds exactly like english speakers learned the languages for few months and tries to speak about some difficult subject with a broken translator’s help

imagine using this in real time on videocalls, you could speak with anyone disregard the language

Very helpful! Thank you!👌👍

As someone who's first language is spanish, that spanish translation was incredible. It sounded amazing.

Polish native speaker here. The translation is not perfect, some sentences are not natural for a polish native speaker. Still, the pronunciation is just incredible! It really impressed me

Turkish speaker here - That speech was fantastic! Very impressive!

German here. There are minor translation issues at the beginning and end, but overall the fluency and expression are impressive. If this is perfected, we will see an age of communication revolution, but also a period of abuse. I'm sure AI will force-transform social media and the media landscape. Social media will become worthless when it comes to socio-political content (videos) and we will probably see a post-analog age (written word) alongside the 5th and 6th industrial revolutions. People will prefer to meet and talk in real life again!

Brazilian feedback here. The translation at the beginning was a little bit weird, but overall the fluency and expression were awesome.

Native German here. The translation is rather bad, but the German itself is 98% flawless. The rhythm, the flow, the pronounciation. Absolutely perfect. It's like you're a German native speaker reading a rather clunky script.

Im here because thumbnail said Turkish, yea turkish translation is pretty good

The second time listening I opened a second browser tab and started it when the first tab playback reached the first English translation. I think the order of the words did change a little. All the different versions were about the same length because the last two were still well aligned. There was a pause in speech but not in expression in the Italian version and then the translation seemed to speed up for a little bit. Since the other translations track so well, I'd anticipate that another translation into Italian would probably be okay. I am curious if HeyGen can do translation on-the-fly during streaming. Also, I wonder how difficult it would be for a professional translator to authenticate such a translation if it were done live, maybe by recording the input & output and being able to annotate the recording with check marks or X marks.

If some hindi speaking person listen to this 05:21 to 05:30 without any context he/she won't even notice that it is AI generated. The speech, speed, voice and even mouth movement is so near perfect to fool any person.

as a french speaker , there are some flaws but the overall perfermance is impressive , and it is still largely better than a human speaking in a broken way...

Polish ⚪🔴 Sounds quite natural like someone who speaks well. There is also sound of breath before speak like natural dialog. Mouth moves are match too.

I think the biggest issue here is that that In India we don't actually speak Hindi like that in a normal way we mix Hindi and English(hinglish) and their are some weird pacing issues

WoW!!!!

Italian feedback. Almost perfect but I perceived some 'glitches' that make it clear that the speaker is not a native Italian. But I know many Italians who speak much worse :)

A queda da qualidade na imagem da região do maxilar me incomodou um pouco. Ainda mais se pensar em um uso para empresas da área da beleza, estética e coisas assim. Masss, a tradução ficou excelente. Tem um leve sotaque mineiro. Mas é muito bom.

i understand spanish, hindi and japanese, all of them sounds good accurate but the speech speed in some part are faster and slower than it should be (normal).

Polish translation is not perfect but fully understandable. Thanks for share.

Turkish speaker here. Translation is a little weird on some sentences. Some words sounded more robotic than natural in the beginning. Pronunciation is very good. It made you sound like a native Turkish speaker with Istanbul(offical&prestige) accent.

Hindi is just 'formal', words that no one really use in casual conversation. It's more like reciting chapters of hindi novel.

Indian here, there are some serious pace issues but overall the translation is nice. The audio is slower than you would normally speak and weirdly speeds up in the middle. Also we usually use a lot of english words even when speaking hindi so it felt like you were forcing yourself to stick to just hindi rather than speaking naturally

Belgian here. The spoken Dutch is from the Netherlands and not from Belgium, which is what I expected. The sentence structure is correct, although I must say that everything is pronounced a bit slower compared to the original. You sound more enthusiastic in the original, it feels a bit sluggish. I also don't really have the impression that I recognize your voice timbre. Not all intonations are correct either I looks like the frame rate is halved compared to the original. All in all still impressive though, if you don't pay attention you could easily fall for it. I currently recognize that generated footage by artifacts in the ears.

EL ESPAÑOL ESTA PERFECTOOOOOOOOO

How did you do it? I looked on HeyGen and could not find an option of dubbing over.

As a Chinese, I can hear that there are so many grammar mistake, we can still understand but it will be so weird.

Chinese native speaker is here, the pronunciation is incredible, however the translation is a liitle bit stiff

The French translation is good but it sounds like several accents were mixed-up. sometimes you sound french, sometimes canadian and sometimes you sound like an american who speaks perfect french but still has a slight american accent. the result is amazing but doesn't sound natural.

Português tá perfeito

Italian - WOW

The French (which has a Canadian accent) is slightly off in the translation

Italian speaker here... The voice is acceptable and the pronunciation is accurate (considering that Italian language is made of lot's of different sound, nuances and dialects). Sometimes, in general, the sound of the voice is a little bit creaky and not so clean as expected. For sure it will be more accurate in the future. Anyway this whole AI thing is impressing... [EDITED] The translation is not 100% accurate.

Polskie tłumaczenie jest trochę koślawe. Np. jest: "jak się porusza usta" (trzecia osoba, liczba pojedyncza) a powinno być "jak się poruszają usta" (trzecia osoba, liczba mnoga). Poza tym brzmienie jest bardzo dobre ale nie jest idealne. Jeśli ktoś nie wie co to A.I. i że potrafi robić takie rzeczy, to może się nabrać ale ludzie świadomi będą potrafili się zorientować, że to robota sztucznej inteligencji. Polski brzmi jakby był odrobinę przyspieszony, zapewne dlatego, że jest bardziej rozwlekły od angielskiego i aby zmieścić się w tym samym czasie, słowa muszą być wypowiadane szybciej.

The Korean one sounds like he was eating something while speaking. The curse of bringing over the American inflections over the consonants I guess 😂 I get that you need to still retain your "voice signature", but man, he sounds like he's drowning 🤣 TLDR: Korean sounds like how you differentiate American Cleo to Australian Cleo

Dutch > it sort of overly pronounces words, and is very monotonic, which makes it a bit robotic. Some words like 'the/an' in Dutch were missing in the last sentences, which is not natural in Dutch to do. However, what bothered me most was how slow he is speaking. I am curious if it adapts to the speed of a language?

Ciesz się (jeżeli wybrałeś kierunek lingwistyczny na dowolnych studiach wyższych 😅)

the korean translation is shaky but the accent is excellent.

Advanced Japanese speaker here. Major mistakes, highly unnatural direct translation, and needs a lot of work. You wouldn't understand it at all unless you heard the original English it was being translated from. But that's not surprising since English-Japanese is one of the hardest language pairs.

هل يمكنك فعل ذلك باللغة العربية؟

Your french sound exactly like Justin Trudeau

13:56 한국어

Turkish is wonderful. we say ohaaa

Timestamps 😅

Polish translations is not great, you can tell that it was AI translated right away.

Wanna see Thai language

진짜 놀랍다

If I don't know better, I'd thought you are some polyglot trying to flex his multi language skills on KZfaq 😅

Turkish doesn’t look/sound natural - extremely slow and word choices are off for the most parts. The last section of it, however, sounded somewhat better.

Turkish native speaker here. Translation has some minor problems but still keeps the overall meaning. My subjective view on the tone/accent/voice : it sounds like a native Turkish speaker (flamboyant) gay man =) What I mean is : in a way the pronounciation is perfect but I don't think if Jon Finger would sound like this if he lived in Turkey for 15 years and perfected his Turkish accent. Someone else could sound exactly like this though.
