What customers say about Sonix's automated transcription 
I was truly amazed by the quality of the transcript I received from you.
I tried 4 other services, and Sonix is the easiest to use, most accurate, and more reasonably priced for the quality.
Researched and did trials of at least 12 other services. Chose Sonix because of accuracy and simplicity.
Very high quality transcription - very accurate - only took a quick scan/sweep to manually correct/clean up the text.
I've used other platforms that don't do a good job at all. Sonix was close to perfect!
I am very happy with the quality of the transcriptions! Having tried numerous other services, none can compare based on the quality for the value.
