Retrospective edition / VOICE

Design voice as a live session

Transport, ephemeral access, turn detection, interruption, tools, reconnect, and playback state jointly define the experience.

01 / DECIDE

Architecture decision

Use it for low-latency speech interaction where file-based audio would feel discontinuous.

Transport, ephemeral access, turn detection, interruption, tools, reconnect, and playback state jointly define the experience. Map input, output, state, tools, and side effects as one observable path, then name the owner of design voice as a live session.

02 / OPERATE

Three-step field procedure

  1. 01

    Lock the contract

    Write down the caller, data classification, success condition, timeout, cancellation, and ownership. Use it for low-latency speech interaction where file-based audio would feel discontinuous.

  2. 02

    Run one bounded path

    Build one end-to-end path with correlation, typed state, and reversible failure handling. Transport, ephemeral access, turn detection, interruption, tools, reconnect, and playback state jointly define the experience.

  3. 03

    Verify the signal

    Turn acceptance into a repeatable fixture, contract test, or browser test. Tests cover jitter, double-talk, reconnect, late tools, device changes, and clean shutdown.

03 / BOUND

Operational boundary

Never expose long-lived keys to clients; interruption must cancel stale audio and tool work.

04 / PROVE

Acceptance evidence

Tests cover jitter, double-talk, reconnect, late tools, device changes, and clean shutdown.
