Aliasing-free L-F model and its application to an interactive MATLAB tool and test signal generation for speech analysis procedures

Hideki Kawahara


This demo introduces a closed form representation of the L-F model for excitation source. The representation provides flexible of source parameters in continuous time axis and aliasing-free excitation signal. MATLAB implementation of the model combined with an interactive parameter control and visual and sound feedback is a central component of educational/research tools for speech science. The model also provides flexible and accurate test signals applicable to test speech analysis procedures, such as F0 trackers and spectrum envelope estimator.
