Software Corrections of Vocal Disorders

open access: yes, 2001
We discuss how vocal disorders can be post-corrected via a simple nonlinear noise reduction scheme. This work is motivated by the need of a better understanding of voice dysfunctions.

Voice quality has robust visual associations in English and Japanese speakers

open access: yesOpen Linguistics
While most studies on sound symbolism have examined the meaning of consonants and vowels, suprasegmentals can also have meaning. English and Japanese speakers rated systematically created novel words (e.g., /ába/) pronounced in four types of voice ...

The design of a digital voice data compression technique for orbiter voice channels [PDF]

open access: yes
Voice bandwidth compression techniques were investigated to anticipate link margin difficulties in the shuttle S-band communication system. It was felt that by reducing the data rate on each voice channel from the baseline 24 (or 32) Kbps to 8 Kbps ...
