How to Lower Transcription Latency in Voice AI Systems: Practical Tips

1. 1Use VAPI's streaming STT with partial transcripts to reduce batching latency
2. 2Implement Twilio's WebSocket connection for raw PCM audio
3. 3Enable early partial results for faster transcription
4. 4Implement barge-in detection on interim transcripts to prevent unnecessary processing
5. 5Test and optimize transcription latency using metrics like time-to-first-token

Developers and engineers working on voice AI systems can benefit from these tips to improve transcription latency and overall user experience
