Low-frequency Fourier analysis of speech rhythm

J Acoust Soc Am. 2008 Aug;124(2):EL34-9. doi: 10.1121/1.2947626.


A method for studying speech rhythm is presented, using Fourier analysis of the amplitude envelope of bandpass-filtered speech. Rather than quantifying rhythm with time-domain measurements of interval durations, a frequency-domain representation is used--the rhythm spectrum. This paper describes the method in detail, and discusses approaches to characterizing rhythm with low-frequency spectral information.
