Translate a WAV audio file. Pass an absolute path — the server transcribes it, translates the text via Claude, synthesises speech, saves `<name>_translated.wav` next to the original, and plays it automatically.
translate_speech
Translate raw audio passed as a base64-encoded WAV string. Returns the transcription, translation, and synthesised audio as base64 WAV — useful for programmatic workflows.
health_check
Verify that all dependencies (Whisper model cache, Piper voice files, `espeak-ng`) are present and ready before making a translation request.
Spanish dialect localization server and CLI. Translates and QA-checks across 25 regional variants with register control, structure preservation, and adversarial quality gates.
Real-time English ↔ Mandarin Chinese speech translation. Transcribes audio locally with Whisper, translates via Claude API, and synthesises speech locally with Piper TTS. Pass a WAV file path and Claude handles the rest.
