Summary
Gives your AI agent pronunciation scoring, speech-to-text, and text-to-speech through a streamable HTTP MCP server. Connects to Brainiall's Azure-hosted APIs with sub-500ms pronunciation assessment that scores phonemes individually, 12-voice TTS at 24kHz, and compact STT with word timestamps. The MCP exposes 10 tools, 8 resources, and 3 prompts for building language learning workflows. You'd reach for this when building tutoring agents that need to evaluate spoken English, generate audio feedback, or transcribe student responses. Requires an API key from the Brainiall portal. Also available are sibling servers for NLP tasks and image processing if you need toxicity detection or background removal alongside speech features.

Authentication for the current API uses an Authorization: Bearer YOUR_BRAINIALL_API_KEY header. Never commit a real key.
For TTS examples for Claude, Cursor, VS Code, n8n, Postman and raw REST clients, use the maintained TTS repository linked above. It is the canonical source for current voices, prices and request schemas.
The small compatibility pack is different from the historical examples. It is an offline-only contract test for buffered TTS, generic diarized-STT review artifacts, a synthetic diarization canary and local-by-default usage planning. It performs no API call during tests, contains no key, copies no third-party source, and does not claim streaming, cancellation, OpenAI drop-in compatibility, completed third-party integration or billing. Read its kill gates before reusing it.
Why this notice exists
External directories and search engines may still link to this repository. This notice prevents an old listing from sending developers to endpoints that no longer work and points them to the maintained production surfaces.

C112 — hosted STT contract fixture
The Whisper-WebUI OpenAI-compatible fixture is a provider-neutral, synthetic request/response example for maintainers evaluating an external speech-to-text path. It does not claim that Whisper-WebUI has adopted the contract, and it never includes a key or private audio.
