Voice-agent teams should use platforms first, then own STT events when failures get weird

A voice-agent builder argues that most teams should start on a platform, but move to custom infrastructure once they need control over the listening layer.
- The post lists common black-box failures: missing partial events, unclear endpointing, bad interruption handling, redaction limits, and no way to tell whether latency comes from STT, LLM, TTS, or tool calls.
- Their view: platforms are fine for validation, but custom infra becomes necessary when failures become hard to debug.
- They sketch a Supabase-style stack with self-owned transcript events, human review for low-confidence calls, confirmation on critical fields, and evals based on actual user behavior.
