  • Introduced stable typed per-turn timing summaries
  • Ensured consistent error handling across providers

New Features

  • Clear stale interim transcripts when calls start or fail
  • Emit `speaking` only when the first server audio chunk is sent

### Patch Changes

- [#2157](https://github.com/cloudflare/agents/pull/2157) [`f08ee06`](https://github.com/cloudflare/agents/commit/f08ee06fd610756de0d8abf539dfe9b746bdd7c5) Thanks [@cjol](https://github.com/cjol)! - Improve voice lifecycle accuracy, diagnostics, and per-turn timing visibility.

  - Clear stale interim transcripts when calls start, end, disconnect, close, or fail during startup.
  - Emit `speaking` only when the first server audio chunk is sent.
  - Add structured, content-free browser diagnostics and structured Worker error logging without reading arbitrary provider response bodies.
  - Report transcriber startup and runtime failures through `onFatalError`, structured client errors, and reliable call cleanup.
  - Preserve model finish reasons and distinguish no-output, output-limit, content-filtered, and model-error completions.
  - Add stable typed per-turn timing summaries for speech, text, terminal outcomes, model streaming, reasoning exposed by the model stream, and overlapping TTS work through `VoiceClient` and the React hooks.
  - Keep the existing four-field metrics wire shape compatible while making no-audio and streamed TTS accounting consistent.
  - Update the bundled voice providers to propagate lifecycle failures and log errors consistently.
