Response design
Short replies, clear fallbacks, measurable timing
For Smart Assistant Voice TTS, generated audio sits inside a larger response loop. Network time, model time, first playable audio, playback, and user interruption are separate measurements.
Keep spoken responses concise, define a text fallback, and test real turn-taking. A demo that never gets interrupted does not represent a live conversation.
Agent acceptance checks
- Set a target for first playable audio and full completion.
- Define cancel, retry, and text-fallback behavior.
- Avoid reading long URLs or interface chrome.
- Test overlapping turns and slow connections.
Turn length
Write Smart Assistant Voice TTS responses for listening and quick interruption. Make the first Smart Assistant Voice TTS checkpoint small enough to revise in minutes, while still representing the final audience and format. Include the most consequential failure case in the Smart Assistant Voice TTS pilot rather than postponing it until after automation.
State handling
Define what happens when audio starts late, fails, or is superseded. Record the script revision, voice, model, reviewer, and decision so the Smart Assistant Voice TTS result can be reproduced after a later change. Record the script revision, voice, model, reviewer, and decision so the Smart Assistant Voice TTS result can be reproduced after a later change.
Observability
Record request, first-chunk, completion, and playback milestones separately. Treat a new audience, locale, channel, or runtime as a new Smart Assistant Voice TTS review rather than assuming the previous decision transfers. Re-run the Smart Assistant Voice TTS reference whenever the source script, voice, model, plan, endpoint, or target playback environment changes.

Review sourceQuestions specific to smart assistant voice tts
What does low latency mean for a voice agent?
Define it precisely—usually time to first playable audio—and report completion time separately.
Should every agent response be spoken?
No. Choose speech when it improves the task and retain accessible visual alternatives.
How should failures sound?
Prefer a concise fallback or text response over repeatedly replaying an old message.
