Yes! Sonix provides precision timing tools in the editor. You can adjust start and end times for each subtitle line, set line breaks, and fine-tune synchronization. Changes are reflected in real-time as you watch the video.
Sonix delivers 85-99% accuracy for Vietnamese transcription depending on audio quality. Our timing algorithm ensures subtitles appear at exactly the right moment. You can review and edit in our browser-based editor before exporting.
VTT format supports basic styling like bold, italic, and positioning. For more advanced styling (fonts, colors, backgrounds), you'll need to use your video editing software or the platform's subtitle customization features after uploading.
There's no limit on the number of subtitle files you can create. Sonix charges per minute of audio/video transcribed, not per export. Create as many subtitle files as you need from a single transcription.

I heard about you from my friend. I found my transcription to be almost exactly what is in the audio file. Love it...continue what you are doing. Sonix is excellent. I appreciate that.
I love the platform and its been a transcription godsend.
It's simply an amazing resource for anyone working with the spoken or written word.
Sonix is light years ahead of all the other solutions I researched and tried!
Amazing for foreign videos that need subtitles. The platform is super easy to use and gave me EXACTLY what I was looking for.
I need to produce very accurate transcripts and the initial transcripts Sonix produces are much better than competitors (I've used many others).
I tried 3 other tools online and I can say that sonix blows them out of the water. I was very impressed with the ease of use, the % of words correctly translated and how simple it ...
Your UI and UX was one of the best I've seen. And I've seen a lot of them. Clean, simple, and pretty easy to edit.
