User reviews

Users praise CaptionSpeaker for its rich customization, automation features, and ease of use, considering it among the best free caption-reading extensions. However, multiple reviews highlight problems such as the extension suddenly stopping to work, synchronization delays with video playback, and limited language support or poor voice quality in some languages. Requests for features like pausing video during speech and improved syncing are common. Despite issues, users find it very useful for accessing foreign language videos with automated caption reading.

Pros

Highly customizable with many setting options to tweak the experience.
Automates volume reduction and language detection, improving usability.
Supports multiple languages and voices with options to adjust pitch and speed.
Starts automatically without needing user intervention.
Free and considered one of the best extensions of its type.

Cons

Sometimes stops working or does not function properly on newer browser versions.
Synchronization issues exist, causing delays or the extension to keep speaking even when video is paused.
Limited support for certain languages such as Arabic, Vietnamese, and Ukrainian; some supported voices are considered low quality.
Occasional pauses between narrated lines causing delays in playback experience.
Lack of pause or control features to better synchronize speech with video playback.

I use this extension almost daily, it was the best one out there in my opinion, especially with all the setting options to tweak it to my liking. Then one day recently it just stopped working, no matter which browser I was using. Please let me know if there is a known fix for it. Thanks in advance!
