This simple shortcut demonstrates using Speechmatics API for speech-to-text (STT)
It’s slower than the built in STT but much better quality. You get 4 hours per month free with their free plan, too 😎 (plus another 4 hours of realtime STT that can’t be used via shortcuts in this way).
Can modify the shortcut to change the transcription language or to have Speechmatics perform translation, sentiment analysis, and other things. See the API documentation for more information (linked in the shortcut).
