描述

The current code does not work well:

  • extraction fails because Python zip does not support multiarchive, we should rely on 7z for example
  • we should expose MIN_SECS / MAX_SECS to the command-line arguments
  • document ffmpeg dependency for audio conversion
  • we use multiprocess for performing one WAV split, but maybe we should also use multiprocess for converting multiple MP3 to WAV in paralell

研究方向
The issue involves improving the Common Voice dataset importer. First, review the current extraction logic and replace Python's zip with 7z to handle multi archive files. Then, add command line arguments for MIN SECS and MAX SECS to allow user configuration. Document the ffmpeg dependency needed for audio conversion. Finally, explore using multiprocessing to parallelize MP3 to WAV conversion. Check the repository's importer module for existing code.
