Transcribing can be hard, especially if the speaker doesn't take proper pauses while speaking. This little script intends to fix that! This script will output a new audio file with the pauses extended!
We analyse the windowed standard deviation of the waveforms and identify regions that are below the mean standard deviation. These regions are considered to be "silence". This assumption only really works for speech, but since we are focusing on transcribing I think it's quite a good assumption.
Installation is quite simple! Either clone the repo and install using python:
$ git clone https://github.com/mynameisfiber/pregnantpause.git
$ cd pregnantpause
$ sudo python setup.py install
$ pregnantpause.py --help
Or by using pip:
$ [sudo] pip install pregnantpause
$ pregnantpause.py --help
Invoking with --help shows the list of usable parameters. One thing to note is that we only operate on WAV files!
