What does ~0.7-second response actually mean, and why does it matter?

It's the gap between the caller finishing a sentence and the agent starting to speak. Past about a second, people talk over the agent or hang up. Hitting ~0.7s takes streaming speech-to-text, token-level LLM streaming, early TTS synthesis, and tuned voice-activity detection — pipeline engineering we've already done in production for TeleVox, not theory from a blog post.

Can you build on our existing phone system and CRM?

Yes. TeleVox runs on Twilio for telephony and LiveKit for real-time audio, and the same architecture connects to SIP trunks, your existing numbers, and your CRM through its API. We've delivered for clients across the US, UK, EU, UAE, and Australia, so regional telephony and compliance differences are familiar ground.

How much does a voice AI agent cost to build?

We quote a fixed price after a scoping call — no open-ended retainers. A focused first version usually means one calling flow, one integration, and real calls in production, delivered across a handful of one-week sprints. Because we operate TeleVox ourselves, estimates come from real operating data. NDA before we hear details, and you own all the IP.

We Don't Just Build Voice AI We Run One in Production

Most agencies wire up an API and call it a voice agent. We founded TeleVox — a production voice-AI SaaS answering real business calls 24/7 at ~0.7-second voice response. If you want a voice AI development company that actually operates one, this is it: LiveKit, Twilio, Deepgram, and OpenAI, running live today.

Why Teams Pick KiswahTech

Operators, not integrators

We founded TeleVox, a voice-AI SaaS whose agents answer business calls 24/7 in production. Every latency trap, telephony edge case, and failure mode you'll hit — we've already hit it, and fixed it.

The full pipeline, tuned to ~0.7s

VAD, streaming speech-to-text, LLM reasoning, text-to-speech, and barge-in handling — built on LiveKit, Twilio, Deepgram, and OpenAI. Roughly 0.7 seconds from the caller finishing to the agent speaking. That number is measured, not marketed.

Outbound that respects the law

Outbound voice AI without compliance thinking is a liability. We build TCPA-aware calling flows — consent tracking, calling windows, opt-out handling — so your agents dial inside the rules, not around them.
