Definition
What is an AI voice agent?
An AI voice agent is software that holds a two-way phone conversation. Unlike a recorded message or a "press 1" menu, it understands free speech, answers questions, asks follow-up questions and decides what to do next.
Businesses use AI voice agents to call leads, answer incoming enquiries, book appointments, send reminders and collect feedback, while their team focuses on the conversations that need a person.
You may also see it called an AI calling agent, AI telecaller, voice bot or conversational voice AI. Troika builds AI voice agents for Indian businesses, in Indian languages and voices.

Inbound and outbound
One voice agent, two jobs
Outbound: the agent works through your list of leads, follows up old enquiries, announces offers and sends reminders, with automatic retries for numbers that do not answer.
Inbound: the agent answers incoming calls with a greeting built for inbound, answers common questions from your own documents, captures the caller's details and transfers urgent callers to a person.

Set-up decisions
Choosing the right voice and language
Pick a voice that fits your brand
Choose from 25+ Indian male and female voices. A calm, warm voice suits healthcare and education; an energetic one suits offers and events. Test two voices on real calls before deciding.
Set a primary and a second language
Each script has a primary language and an optional second language. One primary plus one secondary gives the best quality; too many languages in one flow can confuse callers.
Write for listening, not reading
Short sentences, one question at a time, and numbers spoken the way people say them. What reads well in a brochure often sounds long on a call.
Plan the hand-over
Decide when the voice agent should transfer to a person and to which number, and what happens if nobody answers.
Honest limits
Where AI voice agents work best, and where they don't
Great fit
- First calls to new enquiries
- Qualification with a few clear questions
- Reminders, confirmations and invitations
- Answering common questions on incoming calls
- Booking appointments and callbacks
Better with a person
- Complex negotiation and final closing
- Sensitive conversations, such as medical or financial distress
- Complaints that need judgement
- Anything that needs a commitment the business must approve
A good voice agent recognises these moments and hands over to your team.

FAQ
AI voice agents: common questions
01Is an AI voice agent the same as a voice bot?
They are related. A basic voice bot follows a fixed script and breaks when the caller goes off track. An AI voice agent understands free speech, answers questions and decides the next step, so the conversation feels natural.
02Does the AI voice agent sound human?
It uses natural Indian voices and handles interruptions, but it does not pretend to be a person. The goal is clear, consistent conversations that pass interested callers to your team.
03Which languages do your AI voice agents speak?
English, Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada, Bengali and Malayalam. Each script has a primary and an optional second language.
04Can the AI voice agent hand the call to a person?
Yes. It can transfer the call to your team's number when the caller is interested or asks for a person, with a fallback if nobody answers.
05Can it answer incoming calls?
Yes. Inbound agents answer with their own greeting and script, answer common questions from your documents and capture the caller as a lead.
06How do I try a Troika AI voice agent?
07Can an AI voice agent call thousands of people a day?
It can call many numbers in parallel; how many depends on the channels allocated to your campaign. One of our customers, Omkar Science Tutorial, described calling 1,000 to 4,000 people in a single day.
08Does the AI voice agent work for inbound calls?
Yes. See our AI receptionist page for how inbound calls are answered.
