Sonix is a very user-friendly platform, and they are very transparent about what is included in the monthly fee... It's transcribed very fast and is quite accurate.
Found you through Google. Super easy to use. Transcribed 98% correctly even though it was not a great audio file.
The transcription service was awesome. I can’t thank Sonix enough.
Wow. SPEED. Nice format, easy to read, liked the time stamps and speaker notification. Not a lot of formatting I had to strip before using. Simple.
I really enjoyed how quickly and accurate the transcription system was. Will definitely use again in the future. I have recommended you to a friend.
I'm very happy with the experience. The Spanish translations are superb. I'm in awe!
English dictation is very accurate. And the online editor is easy to use. Also it generates SRT files that I can import in my video editors for further processing.
In one word? FAN-TAS-TIC!! The possibility to split the transcript to subtitles AND split them! THAT IS FANTASTIC!!
