Pdf Vocab Audio

从 PDF 提取词汇生成朗读音频，每个词组读两遍

This skill is mostly coherent for generating TTS from a PDF, but two issues deserve attention before installing: (1) The code uses a hardcoded fallback directory (/root/.openclaw/media/inbound) when you don't pass a PDF path — if you don't want the skill to read agent/internal files, always invoke it with an explicit PDF path. (2) The extraction regex does not actually strip Chinese translations as the documentation states, which may produce mixed-language audio. If you plan to use it, run it in an isolated environment first, verify the outputs on sample PDFs, and consider patching the extraction logic (e.g., capture only [A-Za-z ]+ at line start or split on non‑ASCII) and changing the default inbound path to a safer location. Also ensure edge-tts and ffmpeg are installed from trusted sources.

Type: OpenClaw Skill Name: pdf-vocab-audio Version: 2.0.0 The skill bundle is a legitimate utility for extracting English vocabulary from PDF files and generating audio recordings using edge-tts and ffmpeg. The Python script (pdf_vocab_audio.py) follows security best practices by using parameterized subprocess calls to prevent shell injection, validating dependencies with shutil.which, and utilizing temporary directories for intermediate file processing. No evidence of data exfiltration, malicious execution, or prompt injection was found.
