MATLAB scripts for speech rhythm analysis.
About
This package extracts one of five different speech envelopes from the raw speech wave form, and then looks for discrete events (e.g., lower crossings, peaks) within the signal. By combining amongst the envelopes and events, the user can generate different acoustic landmarks with which to analyse speech rhythm, or use as a time series for correlating with neural signals in speech perception experiments.
In addition to these primary functions, a flexible windowing tool is included. It finds natural silent break points within a desired range (e.g., 4 +/- 2 seconds in duration) to break long audio down into shorter segments.
Usage
Run acousticLandmarks.m with included example.wav to see how the package works.
