How this service works
Voice synthesis API: converts written text (up to 2000 characters) into a natural-sounding spoken-word audio file, delivered as base64 WAV with a choice of five male and five female voice presets. No account or third-party key required, and text is never retained. Suited for voice assistants, IVR prompts, and turning written notifications into audio.
Output
A base64-encoded WAV audio file containing the spoken rendition of the submitted text, synthesized using the selected voice preset. No text is retained after synthesis.
Example use cases
Example prompt
“Read this notification aloud using a female voice (F1): 'Your order has been shipped and will arrive by Friday.' Give me the audio as a WAV file.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/voice-synthesisWhen to prefer
Choose this endpoint when you need a quick, privacy-friendly text-to-speech conversion with no account setup, returning a WAV audio file. Ideal for voice assistant responses, IVR prompt generation, or audio notifications where text is short (under 2000 chars) and one of ten preset voices suffices. Prefer this over full TTS platforms when you want pay-per-use pricing with no retained data.
Side effects
- Text exceeds 2000 character limit — request rejected
- Invalid voice ID provided — falls back to default F1 or returns error
- Empty text field — synthesis fails with validation error
- Malformed JSON body — 400 bad request
- Payment not included or insufficient — 402 payment required
