It was super easy to integrate with AssemblyAI and it provides accurate translations in multiple languages
AssemblyAI is great! Their speech-to-text API is a beast, making it so easy to transcribe audio for our app. The docs are spot-on, super clear, and got us up and running fast. Plus, the control we get over features like speaker detection and real-time transcription is next-level.
We used Assembly for transcription in SnapLinear because they offer speaker diarization and real-time transcription
