+# 天数智芯 天垓150 ASR（FunASR架构）
+
+## 镜像构造
+```shell
+docker build -f ./Dockerfile.funasr-bi150 -t <your_image> .
+```
+其中，基础镜像 corex:4.3.8 通过联系天数智芯智铠100厂商技术支持可获取
+
+## 使用说明
+
+### 使用 FastAPI 启动ASR服务：
+例如：
+```shell
+docker run -dit -v /usr/src:/usr/src -v /lib/modules:/lib/modules --device=/dev/iluvatar0:/dev/iluvatar0 \
+    -v /mnt/contest_ceph/leaderboard/modelHubXC/iic/SenseVoiceSmall:/model \
+    --network=host <your_image> \
+    main.py --model_dir /model --model_type sensevoice --use_gpu --port 1111
+```
+具体参数代码设定可参考代码文件
+
+### 测试ASR服务
+项目根路径`sample_data`目录下附带上了中文的测试音频和附带内容
+
+```shell
+curl -X POST http://localhost:1111/transduce \
+  -F "audio=@../sample_data/lei-jun-test.wav" \
+  -F "lang=zh"
+```
