AI Voice & Greetings

Choose your AI's voice, write its greeting, set its personality, and control what it says.

• How your AI receptionist worksWhen a patient calls, three systems work together in about a second — speech-to-text turns their words into text, a language model decides what to say back, and text-to-speech speaks the response. Knowing the pipeline helps you write better greetings, FAQs, and call scripts.

• What your AI can and can't doYour AI books, reschedules, cancels, answers FAQs, takes messages, and transfers calls. It won't give medical advice, quote prices it doesn't know, take credit cards over the phone, or pretend to be a licensed clinician. This matrix sets expectations for staff and patients.

• Customize your AI greetingYour greeting is the first thing every caller hears. Keep it under 12 seconds, name your practice, set expectations for what the AI can do, and match the warmth your patients expect from your brand.

• Train your AI on your FAQsThe Custom Knowledge field is free-form text your AI uses to answer questions it wouldn't otherwise know — parking instructions, insurance carriers, pre-appointment prep, holiday hours, anything specific to your practice. Add it once and it's used on every call.

There are six built-in scenarios covering booking, rescheduling, cancellations, prescription refills, after-hours calls, and general questions. Run them after every config change.

• Spanish and multi-lingual callsAdd Spanish (or another language) in Settings → AI Voice → Languages. When you list more than one language, the AI auto-detects what the caller is speaking on the first turn and matches their language for the rest of the call. The bilingual voice (Luis) handles English and Spanish equally well.
