Summary

  • Adds AMD speechDurationMs and delayMs result fields, using an explicit zero delay when no speech end timestamp exists.
  • Ports the source AMD short-greeting silence timer behavior so transcripts arriving during the human-silence window replace the pre-baked HUMAN timer without extending the machine deadline.
  • Adds trace attributes and parity/regression coverage for the ported source AMD classifier tests.

Tests

  • pnpm test -- agents/src/voice/amd.test.ts
  • pnpm test -- agents/src/telemetry/traces.test.ts
  • pnpm --filter @livekit/agents build
  • pnpm lint (passes with existing warnings in unrelated files)

Notes

  • pnpm --filter @livekit/agents api:check fails before API comparison on existing API Extractor unsupported export * as ... syntax in agents/dist/index.d.ts.

why are there so many wider reaching changes that weren't part of the original diff?
