Agentic AI that understands, reasons and acts naturally

Most automation mishears the request, guesses at the decision, and sounds robotic delivering it. Agentic AI, part of the Agentic CX Suite, pairs Speech Recognition's understanding with AI Agent's strong decisions and TTS's human voice, so nothing gets lost along the way.

AI Agent

Put Agentic AI to work understanding intent, reasoning naturally, and taking action end to end.
A customer asks about a balance, a transaction, or a routine request, working from the accurate transcript Speech Recognition just produced. Agentic AI's hybrid NLU and LLM reasoning closes it out instantly in most cases, and when it responds, TTS delivers the answer in a natural voice instead of a robotic one.

Speech Recognition

Turn every word into accurate text your business actually speaks, not a generic transcript.
A customer says a product name or speaks with an accent a generic model has never heard, and a generic engine mishears it, sending the request down the wrong path. Speech Recognition learns your vocabulary and accents, feeding AI Agent an accurate transcript from the first word, so it handles request the first time.

Text-to-speech

Make every automated answer sound natural and brand consistent, not like a robotic script reading it aloud.
AI Agent handles  the request correctly, but a flat, mechanical voice undermines the experience, and customers hang up unconvinced they spoke to something that understood them. TTS delivers the answer in a natural, brand-consistent voice across every channel, closing the loop Speech Recognition and AI Agent started.

How it works

Gradient icon showing two arrows circling a square

AI Agent Leads

A customer asks about a balance, a transaction, or an open-ended question, and AI Agent takes it from the first word to the last, using hybrid NLU and LLM reasoning to get it done in most cases, without a queue or a transfer.

Speech recognition we own

Behind that ability is Speech Recognition SESTEK built and owns, not a licensed engine. It learns your vocabulary and accents, so AI Agent understands the request the customer actually made, word for word.

Natural voice we built

The answer comes back in a voice SESTEK built in-house, refined over 25+ years, so the exchange sounds like a real conversation, one the customer trusts, all the way to the end.
