|
||||
- 🎬 **广泛兼容** - 支持常见音视频格式(MP3、MP4、WAV 等)
|
||||
- 🇨🇳 **中文优化** - Paraformer 模型针对中文语音优化
|
||||
|
||||
## 安装前提
|
||||
|
||||
### 1. 安装依赖
|
||||
|
||||
```bash
|
||||
pip install funasr modelscope
|
||||
```
|
||||
|
||||
### 2. 配置环境变量(可选)
|
||||
|
||||
在 `~/.clawdbot/clawdbot.json` 中添加:
|
||||
|
||||
```json5
|
||||
{
|
||||
skills: {
|
||||
entries: {
|
||||
"kb-funasr": {
|
||||
env: {
|
||||
FUNASR_CACHE_DIR: "~/.cache/modelscope/hub"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
或通过命令行配置:
|
||||
|
||||
```bash
|
||||
clawdbot skills config kb-funasr FUNASR_CACHE_DIR "~/.cache/modelscope/hub"
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 基本用法
|
||||
|
||||
```bash
|
||||
# 使用默认 Paraformer 中文模型处理
|
||||
python funasr.py --input video.mp4
|
||||
|
||||
# 后台异步执行
|
||||
python funasr.py --input video.mp4 --background
|
||||
```
|
||||
|
||||
### 指定模型
|
||||
|
||||
```bash
|
||||
# Paraformer 中文模型(推荐)
|
||||
python funasr.py --input video.mp4 --model paraformer-zh
|
||||
|
||||
# Paraformer 多语言模型
|
||||
python funasr.py --input video.mp4 --model paraformer
|
||||
|
||||
# SenseVoice 多语言模型
|
||||
python funasr.py --input video.mp4 --model sensevoice
|
||||
```
|
||||
|
||||
### 指定输出目录
|
||||
|
||||
```bash
|
||||
python funasr.py --input video.mp4 --output ./transcripts
|
||||
```
|
||||
|
||||
## 输出文件
|
||||
|
||||
对于输入 `video.mp4`,将生成以下文件:
|
||||
|
||||
```
|
||||
output/
|
||||
├── video.json # 详细结果(含时间戳)
|
||||
└── video.txt # 纯文本
|
||||
```
|
||||
|
||||
### JSON 格式
|
||||
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"input_file": "video.mp4",
|
||||
"model": "paraformer-zh",
|
||||
"output_files": {
|
||||
"json": "video.json",
|
||||
"txt": "video.txt"
|
||||
},
|
||||
"duration_seconds": 120.5,
|
||||
"segments": [
|
||||
{
|
||||
"id": 0,
|
||||
"start": 0.0,
|
||||
"end": 3.2,
|
||||
"text": "这是第一段识别结果"
|
||||
},
|
||||
{
|
||||
"id": 1,
|
||||
"start": 3.2,
|
||||
"end": 6.8,
|
||||
"text": "这是第二段识别结果"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## 模型对比
|
||||
|
||||
| 模型 | 速度 | 精度 | 适用场景 |
|
||||
|------|------|------|----------|
|
||||
| paraformer-zh | ⚡⚡⚡ | ⭐⭐⭐⭐ | 中文语音(推荐) |
|
||||
| paraformer | ⚡⚡ | ⭐⭐⭐⭐ | 多语言识别 |
|
||||
| sensevoice | ⚡ | ⭐⭐⭐⭐⭐ | 高精度多语言 |
|
||||
|
||||
## 完整示例
|
||||
|
||||
### 示例 1: 转录播客
|
||||
|
||||
```bash
|
||||
python funasr.py --input podcast.mp3 --model paraformer-zh --background
|
||||
```
|
||||
|
||||
### 示例 2: 生成视频识别结果
|
||||
|
||||
```bash
|
||||
python funasr.py --input tutorial.mp4 --model paraformer
|
||||
```
|
||||
|
||||
### 示例 3: 批量处理(配合脚本)
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
for video in videos/*.mp4; do
|
||||
python funasr.py --input "$video" --model paraformer-zh
|
||||
done
|
||||
```
|
||||
|
||||
## 在 Workflow 中使用
|
||||
|
||||
在知识库处理流程中,如果视频没有识别结果:
|
||||
|
||||
```bash
|
||||
# 步骤4: 下载视频后
|
||||
# 步骤5: 使用 FunASR 生成识别结果
|
||||
python funasr.py --input ${video_path} --model paraformer-zh --background
|
||||
|
||||
# 等待 FunASR 完成,然后继续后续步骤
|
||||
```
|
||||
|
||||
## 技术细节
|
||||
|
||||
- **引擎**: 阿里 FunASR
|
||||
- **模型框架**: ModelScope
|
||||
- **音频采样率**: 自动转换为 16kHz
|
||||
- **语言**: 根据模型支持不同语言
|
||||
|
||||
## 故障排查
|
||||
|
||||
### 问题: 模型下载失败
|
||||
|
||||
```bash
|
||||
# 首次运行会自动下载,确保网络稳定
|
||||
python funasr.py --input test.mp4
|
||||
|
||||
# 手动检查缓存目录
|
||||
ls ~/.cache/modelscope/hub/
|
||||
```
|
||||
|
||||
### 问题: 音频格式不支持
|
||||
|
||||
```bash
|
||||
# 转换音频格式
|
||||
ffmpeg -i input.avi -acodec libmp3lame output.mp3
|
||||
python funasr.py --input output.mp3
|
||||
```
|
||||
|
||||
### 问题: 依赖安装失败
|
||||
|
||||
```bash
|
||||
# 使用清华镜像源
|
||||
pip install funasr modelscope -i https://pypi.tuna.tsinghua.edu.cn/simple
|
||||
```
|
||||
|
||||
## 性能参考
|
||||
|
||||
在 CPU 环境下(Intel i7):
|
||||
|
||||
- **paraformer-zh 模型**: ~2x 实时速度(1分钟音频 ~30秒处理)
|
||||
- **paraformer 模型**: ~1.5x 实时速度(1分钟音频 ~40秒处理)
|
||||
- **sensevoice 模型**: ~1x 实时速度(1分钟音频 ~1分钟处理)
|
||||

||||

# KB FunASR Skill
|
||||
|
||||
**kb-funasr** - 本地语音识别,使用阿里 FunASR 将音视频文件转换为文本和 JSON 格式输出。
|
||||
|
||||
## 什么时候使用
|
||||
|
||||
当用户需要:
|
||||
- 将视频/音频文件转换为文字
|
||||
- 获取带时间戳的详细识别结果
|
||||
- 需要中文优化的语音识别(Paraformer 模型)
|
||||
|
||||
## 环境变量
|
||||
|
||||
在使用之前,必须检查环境变量是否已经设置。
|
||||
|
||||
| 变量名 | 用途 | 示例 |
|
||||
|--------|------|------|
|
||||
| `FUNASR_CACHE_DIR` | FunASR 模型缓存目录 | `~/.cache/modelscope/hub` |
|
||||
|
||||
## 使用方法
|
||||
|
||||
```bash
|
||||
# 基本用法(使用 Paraformer 模型)
|
||||
python funasr.py --input video.mp4
|
||||
|
||||
# 指定模型
|
||||
python funasr.py --input video.mp4 --model paraformer-zh
|
||||
|
||||
# 指定输出目录
|
||||
python funasr.py --input video.mp4 --output ./output
|
||||
|
||||
# 异步执行(推荐)
|
||||
python funasr.py --input video.mp4 --background
|
||||
```
|
||||
|
||||
## 命令参数
|
||||
|
||||
| 参数 | 说明 | 默认值 |
|
||||
|------|------|--------|
|
||||
| `--input` | 输入音视频文件路径 | 必需 |
|
||||
| `--model` | FunASR 模型类型 | `paraformer-zh` |
|
||||
| `--output` | 输出目录 | 文件所在目录 |
|
||||
| `--background` | 后台异步执行 | False |
|
||||
|
||||
## 模型选项
|
||||
|
||||
- `paraformer-zh` - Paraformer 中文模型(轻量,中文优化,推荐)
|
||||
- `paraformer` - Paraformer 多语言模型
|
||||
- `sensevoice` - SenseVoice 多语言模型
|
||||
|
||||
## 输出文件
|
||||
|
||||
对于输入 `video.mp4`,将生成:
|
||||
|
||||
- `video.json` - 详细结果(包含时间戳、分段信息)
|
||||
- `video.txt` - 纯文本内容
|
||||
|
||||
## 输出格式示例
|
||||
|
||||
### JSON 格式
|
||||
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"input_file": "video.mp4",
|
||||
"model": "paraformer-zh",
|
||||
"output_files": {
|
||||
"json": "video.json",
|
||||
"txt": "video.txt"
|
||||
},
|
||||
"duration_seconds": 120.5,
|
||||
"segments": [
|
||||
{
|
||||
"id": 0,
|
||||
"start": 0.0,
|
||||
"end": 3.2,
|
||||
"text": "这是第一段识别结果"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Workflow 中的使用
|
||||
|
||||
```bash
|
||||
# 步骤4之后:如果已有音频但无字幕,可以使用 FunASR
|
||||
python funasr.py --input ${video_path} --model paraformer-zh --background
|
||||
```
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
# 1. 安装依赖
|
||||
pip install funasr modelscope
|
||||
|
||||
# 2. 首次运行时会自动下载模型到缓存目录
|
||||
python funasr.py --input test.mp4
|
||||
|
||||
# 3. 复制技能到 skills 目录
|
||||
cp -r kb-funasr/ ~/skills/
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
- **异步执行**: 使用 `--background` 参数时,命令会在后台运行,不阻塞主代理
|
||||
- **模型选择**: paraformer-zh 模型适合中文语音识别,速度较快,精度较高
|
||||
- **文件格式**: 支持 MP3、MP4、WAV、FLAC、OGG、M4A 等常见格式
|
||||
- **首次运行**: 首次运行时会自动下载模型文件,需要稳定的网络连接
