Voice AI

Voice AI is conversational AI that communicates through voice instead of text. It combines speech-to-text (STT), a large language model for understanding, and text-to-speech (TTS) to reply in a human-like voice.

What does Voice AI mean in practice?

Voice AI powers AI phone receptionists, outbound lead-calling agents, IVR replacements, appointment booking lines, and post-enquiry follow-up calls. The classic stack is: (1) speech-to-text converts the caller's audio to text; (2) an LLM interprets intent and chooses the next action; (3) text-to-speech turns the response into audio. Newer speech-native systems process audio more directly, which can reduce lag and interruptions. For Indian businesses, voice AI quality depends on regional accent handling, code-mixed speech, local telephony reliability, clear call transfer rules, WhatsApp follow-up after the call, and pricing that makes sense for short customer conversations. A good buying test is simple: ask the voice agent pricing, appointment, cancellation, address, and language-switching questions in one call. If it cannot recover from interruptions or confirm the next step, the demo voice quality does not matter.

Real example

A customer calls a clinic's Dvaarik phone number. The AI picks up, greets in Hindi, asks 'aap kis doctor se appointment chahte hain?', understands 'Dr. Neha ke saath', books the appointment, and reads back the confirmation in voice.
