The script “detect_silence_speech.praat” provides an automated method to detect silence based on a sound file. This uses the following specifications:

  1. The Two-pass method for estimation f0 range adapted to each speaker; uses the cross-correlation method
  2. The the range of f0 (between 5-95%) is obtained
  3. Intensity is then computed based on the 95% f0
  4. Intensity range is obtained (between 5-95%); SD is also computed
  5. The silence threshold is estimated based on range - SD/2

Pauses are marked with “xxx”; speech with an empty interval

An outputted TextGrid is provided.
