Next step • Voice AI Agents

Give customers a human‑sounding agent that answers, understands, and acts — in real time.

Now that you can enable WhatsApp Voice, take the next step: deploy Voice AI Agents that converse naturally, handle tasks end‑to‑end, and hand off to humans when it matters. Moreover, keep your brand tone consistent and your data secure.

Conversational by design

Voice AI Agents speak with natural prosody and can be interrupted mid‑utterance. Consequently, customers feel heard rather than processed.

⚙️

Understands & executes

Beyond speech, agents can call APIs, read knowledge bases, and complete tasks such as lookups, bookings, and payments. Furthermore, they escalate with full context.

🧩

Fits your stack

Integrate with WhatsApp Voice, web, or PSTN. Additionally, connect to your SBCs (AudioCodes/Patton), CRMs, and ticketing tools without changing your core.

24/7 availability

Always on, always consistent. As a result, customers get answers without waiting in queues.

Lower handle time

Real‑time understanding and tool use shorten calls. Moreover, resolutions improve.

Deflection with care

Automate routine tasks while preserving human handover for sensitive cases.

Brand‑consistent tone

Choose voices that fit your brand, then guide style with prompts and guardrails.

How it works

A streamlined loop: speech in → intent & reasoning → tools/APIs → speech out. Specifically, the agent stays interruptible and context‑aware throughout.

1

Capture

Low‑latency streaming ASR converts voice to text while the caller speaks.

2

Understand

The agent interprets intent, references memory, and plans the next action.

3

Act

It calls your APIs (pricing, orders, tickets), writes notes, and triggers workflows.

4

Respond

Finally, it speaks back using natural TTS; barge‑in allows immediate course‑correction.

Natural voices & low latency — powered by leading providers

We integrate with top‑tier speech platforms to deliver lifelike voices, fast response, and multilingual options. Your brand voice stays consistent while we handle the engineering.

Lifelike speech

Neural TTS with expressive prosody and optional voice cloning (with proper consent and policy controls).

Streaming & barge‑in

Low‑latency streaming enables natural back‑and‑forth. Callers can interrupt to redirect the agent.

Multilingual

Support for multiple languages and accents so you can serve diverse customer bases.

Why it matters

  • More natural interactions reduce friction and call fatigue.
  • Faster responses drive lower handle times and better CSAT.
  • Consistent voice and tone reinforce brand trust at scale.
