چکیده

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.

A New Cosine Series Antialiasing Function and its Application to Aliasing-Free Glottal Source Models for Speech and Singing Synthesis

We formulated and implemented a procedure to generate aliasing-free excitation source signals. It uses a new antialiasing filter in the continuous time domain followed by an IIR digital filter for response equalization. We introduced a cosineseries-based general design procedure for the new antialiasing function. We applied this new procedure to implement the antialiased Fujisaki–Ljungqvist mod...

A Comparative Study of Gender and Age Classification in Speech Signals

Accurate gender classification is useful in speech and speaker recognition as well as speech emotion classification, because a better performance has been reported when separate acoustic models are employed for males and females. Gender classification is also apparent in face recognition, video summarization, human-robot interaction, etc. Although gender classification is rather mature in a...
