Author: Roko <roko@hidosi.ru>
Date:   Wed Jul 8 13:15:48 2026 +0700

    v2: initial commit — TTS proxy with STT fallback to whisper.cpp
    
    - OpenAI-compatible API on localhost:9998
    - TTS → RouterAI /v1/audio/speech (Google Gemini Flash)
    - STT → RouterAI → whisper.cpp fallback
    - Health endpoint, CORS, config from openclaw.json
    - systemd service unit

+# routerai-voice-proxy
+
+OpenAI-совместимый HTTP-прокси для TTS и STT через RouterAI API.
+
+**Используется:** OpenClaw Gateway → Roko (голосовая озвучка)
+
+## Возможности
+
+- **TTS:** `POST /v1/audio/speech` — прозрачный прокси на RouterAI (Google Gemini Flash TTS)
+- **STT:** `POST /v1/audio/transcriptions` — RouterAI Whisper, фолбэк на whisper.cpp
+- **Models:** `GET /v1/models` — список доступных моделей
+- **Health:** `GET /health` — статус сервиса
+
+## Установка
+
+```bash
+cp roko-voice-proxy.service ~/.config/systemd/user/
+systemctl --user daemon-reload
+systemctl --user enable --now roko-voice-proxy
+```
+
+## Конфигурация
+
+Читает `~/.openclaw/openclaw.json`:
+- `models.providers["routerai-ru"].apiKey` — ключ API
+- `messages.tts.providers.openai` — модель, голос, формат
