Voice bot

A voice bot is software that talks with people over the phone or another voice channel. Older voice bots follow fixed scripts and recognise a short list of phrases. Newer ones use speech recognition and language models to hold open conversations, and are usually called AI voice agents.

How a voice bot works on Indian calls

Picture a courier company's helpline. A scripted voice bot asks, "Please say your tracking number," and listens for digits. If the caller says, "Mera parcel kal aana tha, abhi tak nahi aaya," nothing matches its list, so it asks the same question again.

An AI-led voice bot hears the same sentence and gets the point: a delivery is late. It asks for the order number, notes it and tells the caller what happens next, in Hinglish if that's how the caller spoke.

Voice bot or AI voice agent?

The two names overlap. "Voice bot" is the older, broader word and still the phrase most people search for. "AI voice agent" usually means the newer kind, one that works towards a goal, copes with interruptions, switches language and takes actions such as booking a slot or transferring the call.

When you compare products, look past the label. Ask two questions: can it hold an unscripted conversation, and what does it do once the call ends?

Why it matters

A voice bot that only understands exact phrases frustrates callers and sends them to your team anyway. One that understands everyday speech can settle routine calls on its own and leave the hard ones to people.

Where Kallix fits

On Kallix you build AI voice agents, the newer kind. Each one has an objective, a script with if/then branches and a set of FAQs. It says it's an AI assistant in its first line and offers a person on request. After every call it saves an outcome and can send a WhatsApp follow-up.

People often use the two names for the same thing. Strictly, a voice bot can be a simple scripted system, while an AI voice agent understands open speech and takes actions such as booking or transferring a call.

Scripted voice bots usually struggle when Hindi and English mix. AI voice agents built for India, including Kallix agents, follow the caller when they switch language.

On Kallix, yes. Every agent says it's an AI assistant in its first line and offers a person on request. Being open from the start is Kallix policy.
