抖音视频转录 Skill
将抖音视频下载音频,用 SenseVoice-Small 转录为文字,存为 Markdown 文件。
环境要求
# Python 3.9+
python -m venv .venv
source .venv/bin/activate
# 依赖
pip install funasr modelscope torch torchaudio
# 系统依赖
# macOS: brew install ffmpeg
# Ubuntu: sudo apt install ffmpeg
使用方法
python scripts/transcribe.py "https://v.douyin.com/xxxxx"
流程(3 步)
Step 1: 从抖音下载音频
使用 iesdouyin.com/share/video/<id> + 移动端 UA 获取 window._ROUTER_DATA,提取 CDN 下载链接。
关键点:
- ✅
iesdouyin.com/share/video/而非douyin.com/video/ - ✅ 移动端 UA 必须用 iPhone
- ✅
playwm→play去水印 - ✅ 无需 cookie、无需登录、无需 yt-dlp
Step 2: SenseVoice-Small 转录
from funasr import AutoModel
from funasr.utils.postprocess_utils import rich_transcription_postprocess
model = AutoModel(
model="iic/SenseVoiceSmall",
trust_remote_code=True,
vad_model="fsmn-vad",
vad_kwargs={"max_single_segment_time": 30000},
device="cpu",
)
result = model.generate(input=audio_path, language="zh", use_itn=True, batch_size_s=60)
Step 3: 生成 Markdown
自动创建带 frontmatter 的 Markdown 文件。
性能数据
| 视频时长 | 模型加载 | 转录耗时 | 总耗时 |
|---|---|---|---|
| 10 min | ~30s | ~25s | ~1 min |
| 30 min | ~30s | ~75s | ~2 min |
| 1h 22min | ~40s | ~180s | ~4 min |
已知限制
- SenseVoice-Small 模型首次下载约 893MB(从 ModelScope,国内快)
- CPU 推理质量略低于 GPU,但中文仍优于 Whisper-small
- VAD 自动切分可能把长停顿处切成两段
- 不支持说话人分离
- yt-dlp 不可用(需要 cookie),必须走 iesdouyin 路线
