A voice for your app
Sound great in 5 minutes.
Call Speak with the same /v1/audio/speech contract your OpenAI client already uses. Audio streams from the first byte, so your UI feels instant.
How it works
- 1
Pick a voice
Choose from 144 stock voices, or your own cloned/designed voice.
- 2
Stream it
Play progressively from the first byte for sub-100ms perceived latency.
- 3
Ship it
It's the OpenAI shape - change base_url and key, and you're done.
What this replaces
Manual coverage gaps
Add streaming text-to-speech that starts playing in milliseconds. That means fewer missed calls, fewer handoffs without context, and fewer hours spent catching up after the fact.
Stacked AI bills
Teams often pay separately for transcription, speech, realtime models, telephony, QA, and orchestration. PyAI keeps the core voice workflow on one usage-based stack.
Slow experimentation
Start with a free key, replay real conversations, compare latency and cost, then route production traffic only when the numbers and customer experience hold up.
Common questions
How does PyAI support a voice for your app?
Call Speak with the same /v1/audio/speech contract your OpenAI client already uses. Audio streams from the first byte, so your UI feels instant.
What does it cost to test this use case?
Speak realtime text-to-speech is billed per minute, with free voice cloning enrollment and prompt-to-voice design. Every account starts with free credit, so teams can test real call flows before committing budget.
How does this reduce wasted AI spend?
PyAI reduces duplicated vendor bills, manual review work, and migration drag by putting transcription, speech, realtime agents, grounding, and call intelligence on one OpenAI-compatible stack.
How do we keep call quality high in production?
Ground the agent in your own content, bind tools for real actions, warm-transfer when needed, and use Trace or Recap when calls require QA, compliance review, summaries, and audit evidence.

Use an instant sandbox key for the API, or open Agents Beta and build without code. Sandbox usage never bills. Live keys require available credit.
Agents is live in beta. Sandbox keys have daily limits and never touch billing.
