Build a voice-cloning product
Give every user their own voice.
Enroll a user's voice once (free), then synthesize with it through Speak - pay only for audio out. Designed (prompt-to-voice) voices are free to create too.
How it works
- 1
Enroll a voice
Submit a reference clip; enrollment is free and returns a voice_id.
- 2
Synthesize
Pass the voice_id to /v1/audio/speech and stream the result.
- 3
Scale per-user
Plan limits cover up to unlimited cloned voices on higher tiers.
What this replaces
Manual coverage gaps
Enroll voices for free and synthesize with them on demand. 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.
Questions buyers ask
How does PyAI support build a voice-cloning product?
Enroll a user's voice once (free), then synthesize with it through Speak - pay only for audio out. Designed (prompt-to-voice) voices are free to create too.
What does it cost to test this use case?
Speak realtime text-to-speech is $0.06/min, 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.
Stop paying for stitched voice AI.
Start with a free key, 10,000 Hear minutes every month, and $50 in credits. Test the same OpenAI-compatible stack you can take to production with Omni, Agents, and Trace.
