Reduced latency by 3x

  • Optimized WebSocket streaming eliminates the round-trip overhead of REST-based transcription APIs.
  • Custom AudioWorklet captures 100ms PCM chunks at 16kHz, minimizing buffering latency at the source.
  • All benchmarks run simultaneously on the same audio to ensure fair, apples-to-apples comparison.
  • Open-source models mean no vendor lock-in — deploy on your own infrastructure with full control.
