Mel Spectral Flux (MSF): A Normative Implementation in C

MSF, the negative logit of the cosine distance between consecutive Mel spectra, is an easy-to-compute instantaneous-frame correlate of speaking rate. The representation was developed with Anna Hjalmarsson, at the Department of Speech, Music and Hearing at KTH, to detect final lengthening. It is currently being explored to detect final creak, to characterize voice quality, to aid in second-language learning, and to quantify rate of speech (ROS) in general conversational settings.

msf-0.3.2.tar.gz (30 May 2011)
- depends on FFT code from the Fastest Fourier Transform in the West (version 3.2.2)
- alternatively, links against FFT code derived from Numerical Recipes in C
- depends on audio file access code from libsdfile (version 1.0.24)

To reproduce the results from (Hjalmarsson & Laskowski, 2011):

obtain the file dealsnippets.tar.gz from Anna Hjalmarsson and place in SOMEPATH
obtain Makefile.INTERSPEECH2011 and place in SOMEPATH
change directory to SOMEPATH and run "make -f Makefile.INTERSPEECH2011 all"
the Makefile downloads, builds and executes all required code to produce encapsulated PostScript of Figures 1, 3 and 4, as well as the text for Table 2 and other miscellaneous numerical results found in the paper
