Voice AI FAQs.
No. We use ElevenLabs, PlayHT and OpenAI voices with sub-500ms latency and interruption handling. Most callers don't realise for 30+ seconds.
Latency budget — where the human-vs-robot line is
Callers tolerate ~800ms of silence before the call feels broken. Every millisecond in the pipeline counts.
| Stage | Target | Typical | Optimisation |
|---|---|---|---|
| End-of-speech detection | 150-250ms | 300ms+ | VAD tuned to language, not defaults |
| Speech-to-text | 150-300ms | 400-800ms | Streaming STT, not batch |
| LLM first token | 200-400ms | 600-1500ms | Small model on hot path, big for cold |
| Text-to-speech first audio | 150-250ms | 300-500ms | Streaming TTS with chunk-1 pre-warm |
| Total perceived | <800ms | 1.5-2.5s | End-to-end streaming, no batch stops |
| Interruption handling | <100ms | Often broken | Barge-in detection on VAD, cancel TTS |
Call design principles that beat script-writing
Great voice UX is not a good script. It's a set of principles the model + flow follow.
- One question at a time
Callers can only hold one question in short-term memory over voice. Multi-part questions get 40%+ misrecognition.
- Confirm before commit
Any booking, transfer, or spend gets read back with a yes/no confirmation — cuts "AI booked the wrong date" complaints to near zero.
- Fail forward
Two failed recognitions on the same slot → offer to text a link or transfer to human. Never a third "sorry, I didn't catch that".
- Time-of-day tone
Different opener at 11pm than at 10am. Small human touch, disproportionate NPS lift.
- Named agent
"This is Ria from Sunrise Dental" outperforms "AI assistant" on trust — as long as you're honest when asked.
- Post-call summary
WhatsApp/email summary of what was booked or promised. Reduces disputes; removes "the AI said something else" as a category.
