How Japanese AI voice agents works
An AI voice agent listens to a caller, works out the next response, uses permitted business tools and speaks back. Unlike a spoken menu, it can follow corrections and help complete a multi-step task.
Build natural customer conversations for reception, appointment booking and support, with a path to a person when needed. Use Agents to configure and save the experience; Omni runs the realtime conversation. Omni brings speech and reasoning together in one fused speech-to-speech model, with native 8 kHz phone audio and interruption handling.
The complete conversation
Choose a consistent polite register and test corrections to a date or time. Avoid treating a polite acknowledgment as confirmation that a requested business action completed.
How PyAI approaches ai voice agents
Quality on the actual call
Evaluate the audio your callers hear, the details the system captures and the action it completes. Native 8 kHz phone audio is available in Omni; use the supported audio format for each product.
A clear integration path
Hear and Speak offer OpenAI-compatible speech endpoints. Omni uses the realtime PyAI SDK. Pair the conversation with AMD, Trace, Recap and managed telephony where your workflow needs them.
Predictable usage billing
Review the product meter, sandbox limits and managed telephony terms on the pricing page. Cloning enrollment and prompt-to-voice design are free; generated speech follows synthesis billing.

Voices, accents and your own voice

For generated speech, you can also enroll a voice you have permission to use or design a voice from a prompt. Verify language and product compatibility before using the result.
