- Deceptive advertising. It promises quality dubbing but only delivers robotic voices from 20 years ago. Furthermore, it blocks access after 5 videos, demanding money without prior notice. It's a pay-to-win scam.
- Sorin Acela
- This is false advertising by using a misnomer. DUBBING is a performance and a production process. A single AI person doing all voices — regardless of gender — is not considered DUBBING in any professional context. It is rather a simple voice-over translation. So all the video sounds are removed and you only get a simple AI reading of the CCs. Removing the original voices, keeping the ambiental sounds then adding adequate voices is easily feasible with today's AI. Using the YouTube automated translated CCs is better than this extension that uses a voice that spoils the whole video. Verdict: useless.

- Speaker recognition is not working for me. When multiple speakers are added, the video is till dubbed by the default voice for all speakers, even after I get the 2 confirmation emails saying the video is ready. Can you please help?

- I have found that this add-on (Youtube-Dubbing) is crashing Brave Browser after 10 to 20 seconds of use. I had to discontinue use. It still works fine on FF and Zen.

- It says I'm a VIP until tomorrow. When tomorrow comes, will the dubbing stop working, or can I use it for free?

- Why did you change my country's flag?! If you have trouble serving Iranians, you could have just not included the Iran option in your extension.
- tai trantuan

- Shimaa Dabour
- its amazing but there is a small glitch that make noise sound some time may be 2 or 3 in any video its like a glitch come from original voice i think you need to prevent original voice in code i know there is an option in setting but as i say its a glitch
- Shimaa Dabour

- Roomer

- Reihan Amri Fatan
- Your platform is amazing, it really helps me to watch educational videos from all over the world youtube creators!
- Chen Lieberman
- I tried watching something in Hindu, sound quality of the video is good but It's dubbing total gibberish. Maybe it works with other languages I didn't try. I think the language detection isn't working great so it was useless for me

- recently I'm not sure if there have been any updates, the dubbing system is identifying most videos as music videos while they are actually discussion videos. It's terrible to be paying and have such irresponsible updates, with no place at all to submit feedback.

- good synch dubs

- I was watching a video that was over two hours long. At first, it worked fine for about an hour. Then I had to turn off my computer for 3–4 hours. When I came back and tried to play the same video again, it showed the message "Music video cannot be translated or dubbed", even though it had worked normally before. The Chinese translation I found was also very poor, laggy, and almost unusable. 𝙝𝙚𝙧𝙚 𝙞𝙨 𝙩𝙝𝙚 𝙪𝙥𝙙𝙖𝙩𝙚: thanks for supporting me. everything is back to good <3
- Paulo Dunham
- Above it says that we can watch 5 videos per day for free. I started watching a video yesterday and didn't finish it. Today I went back to the same video and I can't translate it anymore. So it seems to me that the information above is false.

- works great! finally a way to watch these indian/russian tutorials that have terrible audio

- Subject: Issue with YouTube Dubbing – Subtitles available but no dubbing Message: Hello YouTube Team, I am experiencing an issue with the YouTube Dubbing feature: The video has English subtitles, but when I try to enable Vietnamese dubbing, the system shows an error and no dubbing plays. I have ensured all extension permissions are granted and third-party cookies are enabled, yet the problem persists. The error seems related to “requestStorageAccessFor: Permission denied” in the console and prevents dubbing from working even though subtitles are present. Could you please investigate and provide a fix? Thank you for your support.
- Denzel
- Why is it randomly speeding up and slowing down the video? no point changing the playback speed because it will just change by itself randomly. Captions will pop up when there's no one talking and no letters on the screen because the video is either ahead or behind of the captions.
- Ibrahim Sako
- wow ❤️❤️I love it, it's beautiful. Thank you so much for a jewel.
- Mauricio Dominguez
- The concept is fabulous and very useful. But............ - I’m a little annoyed that I can’t choose which videos to activate it on and which ones not to. - I’d like to be able to decide what to do, like if I only want subtitles or just the audio. - Once it’s activated on a video, I can’t turn it off. - I don’t quite understand, but when the video starts playing, it gets slow for a moment and then goes back to normal.

- The quality is super bad. You literally can't hear the original audio track and the music because of the dubbing.
