Amazing for foreign videos that need subtitles. The platform is super easy to use and gave me EXACTLY what I was looking for.
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
Easy to use and it saved me SO much time transcribing.
Sooooooooooo easy to use and accurate.
Amazed by the software even in quite mixed audio!
I had been using Dragon voice recognition software, but Sonix eliminates that step all together. I absolutely love Sonix.
Found you through Google. Super easy to use. Transcribed 98% correctly even though it was not a great audio file.
In one word? FAN-TAS-TIC!! The possibility to split the transcript to subtitles AND split them! THAT IS FANTASTIC!!
