Recording Guidelines

  1. Peak amplitude should range between -21 dBFS and -6 dBFS.
  2. Record in a quiet environment with background noise <50 dBSPL. Ensure SNR >25 dB.
  3. No distortion, missing samples, or chopping.
  4. Normal speech speed, verified by subjective listening.
  5. Segment each wake word into separate .wav files, ensuring no part is cut off, with front/rear silence trimmed to <0.1 sec.

Non-Wake Word Recording

  • Each speaker must read 4 minutes of unique sentences, avoiding any selected wake words. Content should differ for each speaker and vary across the 4 languages.
