AI Voice Agents
Advanced voice agents with full telephony integration — answering and placing real phone calls in 25+ languages, including Thai.
Get StartedWe build production voice agents that hold natural phone conversations — not chat widgets with a microphone. They answer inbound calls and place outbound ones over real phone lines, speak 25+ languages including Thai, and connect to your CRM, booking, and support systems to actually get things done: qualifying leads, confirming appointments, answering account questions, and handing off to humans with full context when it matters. We hold ourselves to the same standard we sell — every call to the OOZOU office is answered by Lilly, the voice agent we built in-house.

Concrete capabilities we bring to this engagement — not buzzwords.
Full Telephony Integration
Inbound and outbound calling over real phone lines — SIP, PSTN, and existing numbers — with transfers, voicemail detection, and call recording.
25+ Languages, Including Thai
Natural speech recognition and synthesis across 25+ languages, with first-class Thai support and mid-call language switching.
Natural, Low-Latency Conversation
Sub-second responses, interruption handling, and voices tuned to your brand — callers talk normally, the agent keeps up.

Agents that act, not just talk: booking appointments, updating CRM records, checking orders, and escalating to humans with full context.

Frequently Asked Questions
Straight answers about how we work.
What can OOZOU's AI voice agents do?
They answer and place real phone calls: qualifying leads, booking appointments, handling support queries, and routing to humans when needed, with transfers, voicemail detection, and call recording. They speak more than 25 languages, including Thai and English.
Do the voice agents work with our existing phone numbers?
Yes. We integrate with SIP and PSTN telephony through providers like Twilio and LiveKit, so agents can run on your existing numbers alongside your current call flows.
Can I try an OOZOU voice agent before committing?
Yes. Call the live demo number on this page and talk to one. A typical engagement then starts with a pilot around one call flow, proves it works on real calls, and expands from there.
Which technologies power OOZOU's voice agents?
We build on the OpenAI Realtime API and Anthropic Claude, with Deepgram for speech recognition, ElevenLabs for voices, and Twilio, LiveKit, and WebRTC for telephony and audio transport.
