+# ASR-микросервис для calls24.ru
+# Распознавание речи: whisper-large-v3-russian + Qwen3-ASR-1.7B
+
+FastAPI-сервис распознавания речи для анализа записанных звонков.
+Две модели: Qwen3-ASR-1.7B (новее, точнее) и whisper-large-v3-russian.
+
+## Структура
+```
+app/
+├── __init__.py
+├── main.py          # FastAPI app, роуты
+├── engine.py        # Движки ASR (whisper + qwen3)
+└── config.py        # Pydantic Settings
+```
+
+## Запуск
+```bash
+cd /home/neo/workspace/asr-microservice
+~/gigaam-env/bin/python -m uvicorn app.main:app --host 0.0.0.0 --port 8000
+```
+
+## API
+- `GET /health` — статус моделей
+- `POST /transcribe` — загрузка аудиофайла, параметр `model` (qwen3|whisper)
+
+### Пример
+```bash
+curl -X POST "http://localhost:8000/transcribe?model=qwen3" \
+  -F "file=@/tmp/test_silero.wav"
+```
+
+## Конфиг
+Переменные окружения (см. .env.example):
+- `DEVICE` — cuda / cpu
+- `WHISPER_MODEL_PATH` — путь к checkpoint whisper
+- `QWEN_MODEL_NAME` — модель Qwen3-ASR
+
+## Зависимости
+```bash
+~/gigaam-env/bin/python -m pip install fastapi uvicorn python-multipart librosa soundfile
+```
+Модели уже скачаны:
+- whisper: `/home/neo/models/whisper-russian`
+- qwen3: `Qwen/Qwen3-ASR-1.7B` (автоматическая загрузка)
