SparkNG: Interactive MATLAB Tools for Introduction to Speech Production, Perception and Processing Fundamentals and Application of the Aliasing-Free L-F Model Component
نویسنده
چکیده
This article introduces a set of interactive tools for studying fundamentals of speech production, perception and processing. In addition to this voice production simulator, it consists of interactive time-frequency representation, auditory representation visualizer and a vocal tract shape visualizer for introductory materials. It consists of compiled executables for Windows and Mac environment, which do not require MATLAB license. The MATLAB sources of the tools and their constituent functions are publicly accessible under open source license.

Aliasing-free L-F model and its application to an interactive MATLAB tool and test signal generation for speech analysis procedures
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...
متن کاملUsing Modulation Spectrum as a Metric to Quantify Over-Smoothing Effects in Statistical Parametric Speech Synthesis
Interactive realtime tools for education were developed making use of Matlab GUI functions. They are a) a realtime spectrogram with narrowband, wideband and perceptual frequency resolution axes, b) a realtime spectrum monitoring followed by an interactive spectrogram display with sound playback of a rectangular time-frequency region and scrubbing inspection, c) realtime vocal tract shape displa...
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...
