In a sample of 46 children aged 4-7 years with Autism Spectrum Disorder (ASD) and intelligible speech, there was no statistical support for the hypothesis of concomitant Childhood Apraxia of Speech (CAS). Perceptual and acoustic measures of participants' speech, prosody, and voice were compared with data from 40 typically-developing children, 13 preschool children with Speech Delay, and 15 part...

Speech delay in children is closely related to their interpersonal communication. Previous studies have found that 10-20 percent of young experience speech which ultimately affects The purpose this study was examine the effect size different test and correlation results linked children's communication delay. This meta-analysis uses 14 research journals. There are 11 journals using method 3 meth...

Phase processing has been replaced by group delay processing for the extraction of source and system parameters from speech. Group delay functions are ill-behaved when the transfer function has zeros that are close to unit circle in the z-domain. The modified group delay function addresses this problem and has been successfully used for formant and monopitch estimation. In this paper, modified ...

Objective: To analyze the impact of speech therapy combined with audiovisual integration rehabilitation training on intelligence and language recovery children global developmental delay. Methods: A total 60 delay treated in our hospital from January 2021 to December 2022 were selected as research subjects. The divided into two groups according intervention method: control group (n=30) study (n...

• Deduced the mechanics of hearing at low sound pressure levels from measurements of basilar membrane motion. The mechanical properties of individual sections of the cochlea have been determined by examining their collective response to tones of different frequency. The conclusion is that each section acts like a harmonic oscillator with negative damping. The oscillator is controlled by negativ...

The goal of this study was to determine if notably reduced intelligibility is a potential diagnostic marker for children with speech delay and histories of early recurrent otitis media with effusion (SD-OME). Intelligibility was assessed in one 5-10 minute conversational speech sample from each of 281 speakers. The OME histories of 148 of these children with normal speech acquisition were descr...

Synchronization of speech and corresponding Electroglottographic (EGG) signal is very helpful for speech processing research and development. During simultaneous recording of speech and EGG signals, the speech signal will be delayed by the duration corresponding to the speech wave propagation from the glottis to the microphone relative to the EGG signal. Even in same session of recording, the d...

Video conference systems have been widely used. A fix video camera shoots a scene is lacking in changes. There is a method that the computer-controlled camera shoots and finds the sound source. Microphone arrays and distributed microphone arrays are used to localize the sound source based on time delay of arrival (TDOA). In order to minimize the error rate of TDOA, a set of 4 microphone arrays ...
