An AI voice agent is software you talk to out loud that talks back and takes action. Speech-to-text hears you, a large language model reasons and decides, an action layer uses your tools, and text-to-speech answers in a natural voice. Unlike a phone menu, it understands ordinary speech and adapts to what you say.
How a voice agent works
Every voice agent runs the same four-part loop, turn after turn, until your goal is met:
| Stage | What it does |
|---|---|
| Speech-to-text | Turns your spoken words into text the agent can read |
| The brain (LLM) | Reasons through the goal, decides the next step |
| Action layer | Uses real tools — calendar, phone, email, files |
| Text-to-speech | Answers back in a natural human-sounding voice |
The two kinds of voice agent that matter
The voice agent you talk to — Coach
Coach by ALAMOvoice is a voice agent you speak to instead of typing. You say your goal; it handles emails, calls, schedules, and goals by voice — a talking AI character, free to start. Coach AI on Google Play →
The voice agent that answers for you — business voice agents
A business voice agent picks up your inbound calls in a natural voice, books appointments, screens spam, and texts you every lead. Business voice agents →
What voice agents are used for
- Answering business calls — a 24/7 AI receptionist that never misses a lead.
- Personal assistance by voice — talk to Coach instead of typing into an app.
- Booking and scheduling — the agent reads the calendar and books the slot.
- Screening and triage — filtering spam, qualifying callers, routing the real ones.
