BACKGROUND There is strong evidence that bilinguals have a deficit in speech perception for their second language compared with monolingual speakers under unfavourable listening conditions (e.g., noise or reverberation), despite performing similarly to monolingual speakers under quiet conditions. This deficit persists for speakers highly proficient in their second language and is greater in tho...

Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...

Individuals with sensorineural hearing loss have difficulty understanding speech, especially in background noise. This deficit remains even when audibility is restored through amplification, suggesting that mechanisms beyond a reduction in peripheral sensitivity contribute to the perceptual difficulties associated with hearing loss. Given that normal-hearing musicians have enhanced auditory per...

objectives: this paper studies the effect of persian cued speech on the perception of persian language phonemes and monosyllabic words with and without sound in hearing impaired children. cued speech is a sound based mode of communication for hearing impaired people that is comprised of a limited series of hand complements and the normal pattern of speech. and it is shown that it effectively ca...

The presence of irrelevant auditory information (other talkers, environmental noises) presents a major challenge to listening to speech. The fundamental frequency (F(0)) of the target speaker is thought to provide an important cue for the extraction of the speaker's voice from background noise, but little is known about the relationship between speech-in-noise (SIN) perceptual ability and neura...

PURPOSE The present study examines the brain basis of listening to spoken words in noise, which is a ubiquitous characteristic of communication, with the focus on the dorsal auditory pathway. METHOD English-speaking young adults identified single words in 3 listening conditions while their hemodynamic response was measured using fMRI: speech in quiet, speech in moderately loud noise (signal-t...

We present three models of audiovisual speech perception at varying signal-to-noise ratios (SNR). The first model is Massaro’s Fuzzy Logical Model of Perception (FLMP) applied at each SNR. The second model imposes the constraint that the visual response probabilities are the same regardless of the SNR. Both models describe the data well. Root Mean Squared Error (RMSE) corrected for the numbers ...

BACKGROUND speech perception of elderly, in silence and in the presence of background noise. AIM to characterize and compare the hearing abilities of elderly in a monaural speech perception test, in the presence and absence of background noise (Speech Discrimination Test - SDT and Speech Perception in Noise - SPIN). METHOD Participants of this study were 55 subjects of both genders, 60 year...

PURPOSE Speech perception in participants with auditory neuropathy (AN) was systematically studied to answer the following 2 questions: Does noise present a particular problem for people with AN? Can clear speech and cochlear implants alleviate this problem? METHOD The researchers evaluated the advantage in intelligibility of clear speech over conversational speech in 13 participants with AN....
