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
  • playwmplay 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
