"AssemblyAI does a good job with transcription"

5/5

What do you like best about AssemblyAI - Speech to Text API?

I am a college professor and used the AssemblyAI speech-to-text API for a qualitative research project. I had hundreds of interviews in a non-English language that needed to be transcribed. AssemblyAI solved my problem fairly easily. It cost me a lot less than what I anticipated. The transcriptions were very accurate and included the special characters in that language.

There are plenty of videos and sources for those who are new to AssemblyAI.

I could not be happier. Review collected by and hosted on G2.com.
