Voices and speech
How SIMCOAI sounds on a call, how it hears your callers, and what to change when either is not working well.
Picking a voice
Voices are part of the SIMCOAI managed voice system. You pick one in the dashboard and hear a preview before committing it to a live line.
- Open your call settingsVoice options sit alongside greeting and speech settings.
- PreviewListen before you apply. A voice that reads well can still sound wrong for your brand.
- ApplyThe voice takes effect on the next call, not mid-call.
- Test on a real callPreview text is short. A real conversation exposes pacing you will not hear in a sample.
Random voice selection
You can let SIMCOAI vary the voice rather than always using the same one.
| Setting | Behaviour |
|---|---|
| Fixed voice | Every call uses the voice you selected |
| Random voice | SIMCOAI picks from your enabled voices per call |
Careful. Random voice selection needs at least two active voices to do anything meaningful. With one enabled voice it behaves identically to a fixed voice.
How SIMCOAI hears callers
Speech recognition settings affect how quickly SIMCOAI decides a caller has finished speaking. That trade-off is real: react too fast and you interrupt, too slow and the call feels sluggish.
- Noisy environments — callers on speakerphone or in a workshop produce more interim results and more false endpoints.
- Long pauses — callers reading an order number aloud often pause mid-sequence.
- Accents and speed — test with voices representative of your actual customers, not just your own.
Was it any good?
Every call records measurable signals rather than leaving you to guess. See call quality signals for first-reply latency, interruption handling and finish reasons.
