Voice AI
What voice AI is, the speech-to-text, language-model and text-to-speech loop behind it, and where it is used.
Voice AI is artificial intelligence that understands and produces spoken language, letting people talk to software the way they talk to a person instead of typing.
The three-part loop
Modern voice AI runs a real-time loop of three parts: speech-to-text turns what the caller says into words, a language model decides what to say back, and text-to-speech turns that reply into a natural-sounding voice. Each part has to run fast enough that the pause between speaking and hearing an answer feels human.
Where it is used
- Phone support: an AI phone agent answers and handles calls.
- Receptionist: greeting callers, answering questions and booking.
- Outbound: reminders, confirmations and follow-up calls.
- Devices: voice assistants built into phones and hardware.
What makes it accurate for a business
A general voice model does not know a specific company. To answer correctly it is grounded in that company's knowledge base and can call tools to look something up or complete a task, and it hands off to a human when it is unsure.
