OBJECTIVE The objective of this study was to evaluate the relationship between developmental delays and speech perception in pre-lingually deafened cochlear implant recipients. METHODS This study was a retrospective review of patient charts conducted at a tertiary referral center. Thirty-five pre-lingually deafened children underwent multichannel cochlear implantation and habilitation at the ...

The research reported in this paper uses novel stimuli to study how speech perception is influenced by information presented to ear and eye. Auditory and visual sources ofinformation (syllables) were synthesized and presented in isolation or in factorial combination. A five-step contilllium between the syllables /bal and Idalwas synthesized along both auditory and visual dimensions, by varying ...

Speech perception and speech production are skills that rival other impressive human achievements. Even after decades of intense effort, speech recognition by machine remains far inferior to that of human performance. Also, as we have all experienced, speech synthesis has not yet obtained the naturalness and quality of the speech of even a young child. Our research has led us to the view that s...

UNLABELLED Hearing aid. AIM To compare the performance, benefit and satisfaction of users of ITE, CIC and BTE digital hearing aid with noise reduction and omnidirectional and directional microphones. METHOD 34 users of hearing aid were evaluated by means of speech perception in noise tests and APHAB and IOI self assessment questionnaires. Prospective study. RESULTS Better results were obt...

An import~.nt question in speech perception is whether listeners have continuous or categorical information about the acoustic signal in speech. Most traditional experimental studies have been interpreted as evidence for categorical perception. It is also argued in the present paper that more recent results taken as evidence against categorical perception are not unequivocally negative. Accordi...

Background There are many methods for assessing hearing performance after cochlear implantation. Standard evaluations often encompass objective hearing tests only, while patients' subjective experiences gain importance in today's healthcare. The aim of the current study was to analyze the correlation between subjective (self-reported questionnaires) and objective (speech perception and localiza...

OBJECTIVES The first objective of this study was to create a recorded Mandarin Early Speech Perception (MESP) test based on the English Early Speech Perception test (), a closed-set assessment tool for evaluation of early speech perception abilities in children. The second objective was to determine whether each of the MESP subtests is appropriate for children with these abilities. The third ob...

Most of the speech enhancement algorithms use the magnitude of STFT while phase is kept unchanged [3]. In this paper the magnitude of STFT of noisy speech is kept unchanged while the phase is modified. Modified complex spectrum of speech is obtained by combining unchanged magnitude spectrum and modified phase spectrum. This modification results into cancellation of low energy components (noise)...

OBJECTIVES/HYPOTHESIS To describe the clinical experience and characterize the outcomes of cochlear implantation (CI) in children with isolated enlarged vestibular aqueduct (IEVA) as compared to children with enlarged vestibular aqueduct (EVA) associated with other bony labyrinth abnormalities. STUDY DESIGN Single, tertiary care, institutional retrospective review over 2 decades. METHODS Th...
