About

Use findBreaths() to automatically detect speech breathing onsets and ends, then optionally corroborate the results to the acoustic speech envelope using breathSpeechCompare(). Finally, you can use plotBreaths() to visualise the breath onsets and ends in relation to the breath belt signal and, if you have it, the corresponding acoustic data. This plot can help you decide if you need to adjust the default paramaters (e.g., minimum inter-breath interval).

Usage

Run example.m with included example breath belta data and acoustic recording to see how the scripts work.

Future Versions

Plans include a GUI to adjust or reject inhalation events, as well as extract basic breath- and/or speech-related descriptive statistics. As the 'SpeechBreathingToolbox' is under development, reporting issues is appreciated.
