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

متن کاملA 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...
متن کاملA 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...
