Retell AI's Shift to Deepgram v2: Modernizing Voice Agent Transcription

As VAPI's deprecated transcriber endpoints are phased out, Retell AI agents face potential silent failures and call timeouts without migration. Switching to Deepgram v2 reduces latency by approximately 200ms, delivers superior noise filtering, and requires only 15 minutes of configuration per agent. This migration is essential for maintaining reliable voice AI services and improving end-user transcription quality.
