An AI Phone Agent That Never Misses a Call
Missed calls are missed revenue. An AI voice agent picks up instantly, understands natural speech, handles interruptions, looks up information in your systems and completes the task — booking, rescheduling, order status, payment reminders or lead qualification — then logs everything to your CRM.
Stellen Infotech builds custom AI voice agents on modern speech-to-text, large language model and text-to-speech engines, tuned for your scripts, accents and compliance rules. Whether you need an AI receptionist for a clinic in Dubai or an outbound AI call center agent for sales in the US, we design, build and operate it end to end.

AI Voice Agents — Frequently Asked Questions
What is an AI voice agent?
An AI voice agent is software that holds natural phone or voice conversations using speech recognition, a large language model and text-to-speech. It understands callers, retrieves information, takes actions in your systems and hands over to a human when needed.
Can the AI voice agent speak Arabic?
Yes. We build voice agents that speak Gulf and Modern Standard Arabic, English, Hindi and 30+ other languages, and can switch language mid-call.
Will callers know they are talking to AI?
Modern voice agents sound very natural, but we recommend a short disclosure at the start of the call. We follow local consent and disclosure rules for each market.
Does it work with our existing phone number and system?
Yes. We connect through Twilio, Vonage, SIP trunks or your existing PBX, so you keep your current numbers and can route calls to the AI by schedule, queue or overflow.
How much does AI voice agent development cost?
Costs depend on call volume, languages and integrations. A single-use-case agent such as an AI receptionist can go live in three to six weeks; ongoing costs are mainly per-minute speech and model usage, which we optimise.
What happens when the AI can’t handle a call?
It transfers the caller to a human with a summary of the conversation, or books a callback — you define the escalation rules.
