Deepgram Reviews

  1. Fast

    It's fast - but for an API, not the fastest speech-to-text. For a long while I hadn't done research and trusted them. Then tried Whisper and Picovoice. On-device latency is nothing comparable with cloud APIs. If latency is important go with Whisper or Picovoice. If customization is also important go with Picovoice.

    don't get me wrong it's still faster than amazon, Microsoft or Assemblyai

  • Deepgram: $200 Free STT That Makes Voice Coding Actually Work
    Deepgram changed the maths. Their Nova-3 model does real-time streaming transcription fast enough that the text appears as you speak, not after.
