About

YouTube 视频转录 + 翻译 Skill

字幕优先:先抓官方/自动字幕(秒级、免 GPU),抓不到再下载音频用 SenseVoice-Small 转录;英文内容自动翻译成中文,输出中英对照 Markdown。加 --no-subtitle 可强制走音频转录。

为什么需要这个

YouTube 有大量优质英文内容,但很多人没时间看完或语言不通。这个 skill:

  • 转录视频为文字(支持中英文)
  • 英文内容自动翻译成高质量中文
  • 输出中英对照,方便学习

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 yt-dlp
# Ubuntu: sudo apt install ffmpeg && pip install yt-dlp

# 翻译功能(可选,英文视频需要)
export DEEPSEEK_API_KEY="your-api-key"

使用方法

python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx"
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --output ./output
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --no-translate  # 不翻译
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --no-subtitle  # 强制音频转录

流程

Step 1: yt-dlp 下载音频

yt-dlp --extract-audio --audio-format mp3 --audio-quality 128K \
  "https://www.youtube.com/watch?v=xxxxx"

Step 2: SenseVoice-Small 转录

from funasr import AutoModel
model = AutoModel(model="iic/SenseVoiceSmall", ...)
result = model.generate(input=audio_path, language="auto", use_itn=True)

Step 3: 语言检测 + 翻译

  • 中文内容 → 直接输出
  • 英文内容 → LLM 翻译成中文,输出中英对照

Step 4: 生成 Markdown

翻译配置

默认使用 DeepSeek API 翻译。需要设置环境变量:

export DEEPSEEK_API_KEY="your-api-key"

支持的 LLM:

  • DeepSeek(推荐,性价比高)
  • OpenAI
  • 任何兼容 OpenAI API 格式的服务

性能数据

| 视频时长 | 下载 | 转录 | 翻译 | 总耗时 | |------|------|------|------|------| | 5 min | ~10s | ~5s | ~10s | ~30s | | 10 min | ~15s | ~10s | ~20s | ~50s | | 30 min | ~30s | ~30s | ~60s | ~2min |

已知限制

  • SenseVoice-Small 对英文转录准确率不如中文
  • 翻译质量取决于 LLM 能力
  • 长视频翻译可能需要较长时间
  • 部分 YouTube 视频有地区限制
