Epoch is the instant of significant excitation of the vocal-tract system during production of
speech. For most voiced speech, the most significant excitation takes place around the …

We present the Dynamic Programming Projected Phase-Slope Algorithm (DYPSA) for
automatic estimation of glottal closure instants (GCIs) in voiced speech. Accurate estimation …

Learners of a second language practice their pronunciation by listening to and imitating
utterances from native speakers. Recent research has shown that choosing a well-matched …

This study focuses on the development of an objective, automated method to extract
clinically useful information from sustained vowel phonations in the context of Parkinson's …

Epoch is defined as the instant of significant excitation within a pitch period of voiced
speech. Epoch extraction continues to attract the interest of researchers because of its …

This work is focused on the evaluation of different methods to estimate the amount of jitter
present in speech signals. The jitter value is a measure of the irregularity of a quasiperiodic …

Parkinson's disease (PD) is a multi-symptom neurodegenerative disease. There are no
biomarkers; the diagnosis and monitoring of the disease progression require clinical and …

In this paper characteristics of speech produced at different loudness levels are analyzed in
terms of changes in the glottal excitation. Four loudness levels are considered in this study …

Speaker de-identification is the process by which speech is transformed in a way that the
speaker identity is masked, while at the same time the transformed speech preserves …

Speech analysis is traditionally performed using short-time analysis to extract features in
time and frequency domains. The window size for the analysis is fixed somewhat arbitrarily …
