AI receptionist
Also known as: AI phone receptionist, AI answering service, automated phone receptionist, virtual AI receptionist
Definition
An AI receptionist is software that answers a small business's inbound phone calls in real time, conducts a conversation with the caller, captures structured intake details (name, phone, reason for calling), books appointments to the business's calendar, and texts confirmation to the caller — all without a human picking up the phone.
Why it matters
Service businesses (plumbers, dental practices, salons, locksmiths, auto repair, law firms) lose 60-80% of inbound callers to voicemail when nobody picks up — and the rate is worse outside business hours, which is when many emergency-trade calls arrive. An AI receptionist closes that gap: it picks up in 0.4 seconds, every time, even at 9pm on a Sunday, even when 30 calls hit simultaneously. The booking lands on your calendar before the caller has hung up.
How it works
An AI receptionist runs three layers in sequence: telephony (Twilio answers the inbound call), speech-to-text (the caller's audio is transcribed in real time), and an LLM (Anthropic Claude or similar) that conducts the conversation and decides what to do — book an appointment, take a message, page on-call staff for emergencies, route to a specific team member, quote pricing. The AI's response is converted back to speech via a TTS engine (ElevenLabs, with native accents in 32 languages), played through the call. Every conversation is transcribed and logged for the business owner's dashboard.
Examples
- A plumber gets a 9pm burst-pipe call. The AI confirms the address, asks if the water shutoff was found, books an emergency slot, and pages the on-call tech via SMS — all in 90 seconds.
- A dental practice receives a 'book me with Dr. Patel for a cleaning' call. The AI looks up Dr. Patel's hygienist calendar, offers two open slots, books the cleaning, and texts the patient a confirmation.
- A salon gets a bilingual client who switches from English to Spanish (or Vietnamese, Mandarin, etc.) mid-call asking about extensions. The AI follows in native accent, books with the right stylist, and quotes the standard extension pricing.
