```
## 模型下载
由于模型文件较大，请从以下地址下载对应的模型文件：
### 中文模型 (推荐)
- 模型名称: sherpa-onnx-streaming-zipformer-bilingual-zh-en-2023-02-20
- 下载地址: https://github.com/k2-fsa/sherpa-onnx/releases/
- 大小: ~40MB
### 英文模型
- 模型名称: sherpa-onnx-streaming-zipformer-en-2023-02-21
- 下载地址: https://github.com/k2-fsa/sherpa-onnx/releases/
- 大小: ~40MB
### 多语言模型
- 模型名称: sherpa-onnx-streaming-zipformer-multilingual-2023-02-20
- 下载地址: https://github.com/k2-fsa/sherpa-onnx/releases/
- 大小: ~60MB
## 使用说明
1. 下载对应的模型文件
2. 解压到对应的语言目录
3. 确保文件名和路径正确
4. 重新构建应用
## 注意事项
- 模型文件会增加应用包大小
- 建议根据需要只包含必要的语言模型
- 模型文件支持热更新，可以在运行时下载
