REVIEW VOCAL EXTRACTION METHOD IN ACOUSTIC RECORDS

An Acoustic-Phonetic Approach to Vocal Melody Extraction

This paper addresses the problem of extracting vocal melodies from polyphonic audio. In short-term processing, a timbral distance between each pitch contour and the space of human voice is measured, so as to isolate any vocal pitch contour. Computation of the timbral distance is based on an acousticphonetic parametrization of human voiced sound. Longterm processing organizes short-term procedur...

A novel method for the extraction of vocal tremor

Vocal tremor is defined as slow modulation of fundamental frequency or its amplitude [1, 2]. Even though vocal tremor may be attributed to neurological diseases, it may also be a natural stochastic modulation of voice. Many studies try to measure these modulations assuming that they are stationary. Hence, their analysis is limited to small intervals loosing important information about vocal tre...

Acoustic Effects of Vocal Training

Acoustic profiles in vocal emotion expression.

Professional actors' portrayals of 14 emotions varying in intensity and valence were presented to judges. The results on decoding replicate earlier findings on the ability of judges to infer vocally expressed emotions with much-better-than-chance accuracy, including consistently found differences in the recognizability of different emotions. A total of 224 portrayals were subjected to digital a...

Vocal-acoustic pathways in a teleost fish.

Many teleost fish generate acoustic signals for vocal communication by the synchronized, high-frequency contraction of skeletal, sonic muscles. In midshipman, eight groups of brainstem neurons were distinguished after biocytin application to the sonic nerve that, we propose, represent the entire vocal motor circuit. Biocytin-filled terminals were ubiquitous within all areas containing labeled n...
