Recognizing Voice Over IP: A Robust Front-End for Speech Recognition on the World Wide Web [PDF]

, 2001
The Internet Protocol (IP) environment poses two relevant sources of distortion to the speech recognition problem: lossy speech coding and packet loss. In this paper, we propose a new front-end for speech recognition over IP networks.

The Effect of Voice over IP Transmission Degradations on MAP-EM-GMM Speaker Verification Performance

Archives of Acoustics, 2015
Despite the growing importance of packet switching systems, there is still a shortage of thorough analyses of VoIP transmission effect on speech and speaker recognition performance. Voice over IP transmission systems use packet switching.

The recognition of time-compressed speech as a function of age in listeners with cochlear implants or normal hearing

Frontiers in Aging Neuroscience, 2022
Speech recognition is diminished when a listener has an auditory temporal processing deficit. Such deficits occur in listeners over 65 years old with normal hearing (NH) and with age-related hearing loss, but their source is still unclear. These deficits

Band-pass filtering of the time sequences of spectral parameters for robust wireless speech recognition [PDF]

, 2006
In this paper we address the problem of automatic speech recognition when wireless speech communication systems are involved. In this context, three main sources of distortion should be considered: acoustic environment, speech coding and transmission ...

Effects of Slow- and Fast-Acting Compression on Hearing-Impaired Listeners’ Consonant–Vowel Identification in Interrupted Noise

Trends in Hearing, 2018
There is conflicting evidence about the relative benefit of slow- and fast-acting compression for speech intelligibility. It has been hypothesized that fast-acting compression improves audibility at low signal-to-noise ratios (SNRs) but may distort the ...

Compression and its Effect on the Speech Signal [PDF]

Ear and Hearing, 1996
Compression systems are often used in hearing aids to increase the wearing comfort. A patient has to readjust frequently the gain of a linear hearing aid because of the limited dynamic hearing range and the changing acoustical conditions. A great deal of attention has been given to the static parameters but very little to the dynamic parameters.

Speech Signal Compression Algorithm Based on the JPEG Technique

Journal of Intelligent Systems, 2018
The main objective of this paper is to explore parameters usually adopted by the JPEG method and use them in speech signal compression. Speech compression is the technique of encoding the speech signal in some way that allows the same speech parameters ...
