Introducing the VocaBusta Voice API

Today we're opening up the engine behind VocaBusta Studio. The Voice API gives any developer programmatic access to the thing African voice tech has been missing: speech that actually sounds African — in Nigerian Pidgin, Yoruba, Igbo, Hausa, Swahili, Zulu, Twi and more.

Why we built it​

Most text-to-speech treats African languages as an afterthought — a flat accent bolted onto an English model, deaf to tone.

Yoruba and Igbo are tonal: the same letters mean different things depending on pitch. Nigerian Pidgin has its own rhythm. Generic TTS flattens all of it. We trained VocaBusta for real African phonology and tone, with native persona voices per language — Blessing and Sunday for Pidgin, Adunni and Tunde for Yoruba, Adaeze and Emeka for Igbo, and many more.

What you get​

  • Text to speech — natural speech in 12 languages and accents, with expressiveness controls (exaggeration, cfg_weight) and streaming for low-latency playback.
  • Transcription — our Vocabanga ASR model for African languages, with word-level timestamps, and Whisper as a fallback.
  • Voice cloning — zero-shot: clone a voice from a ~10-second clip and synthesize with it in seconds.
  • Video dubbing — analyze a video (transcript + speaker diarization), translate it, and render it re-voiced — preserving each speaker's own voice or swapping in a catalog voice.

Hello, world​

curl https://api.satryx.ai/voice/tts \
  -H "Authorization: Bearer $SATRYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "How far? Welcome to VocaBusta.", "voice_id": "vocabusta_pcm_female"}' \
  --output hello.wav

The response is raw WAV audio; synthesis metadata comes back in the X-Vox-Metadata header.

One platform, two SDKs​

VocaBusta is part of the Satryx platform, so the same first-party SDKs that wrap chat and image generation also cover voice:

  • Python — pip install satryx
  • TypeScript / Node — npm install @satryx/sdk

Every endpoint is plain REST, so any language with an HTTP client works too.

Pricing & access​

Voice generation is gated behind the VocaBusta subscription — activate it in Billing, then create an API key at Account → API keys. Browsing the voice catalog (GET /voice/voices) is free and ungated, so you can audition voices before you subscribe.

We can't wait to hear what you build.
