The effect of musical aptitude on the integration of audiovisual speech and non-speech signals in children
نویسندگان
چکیده
Multisensory integration was assessed using two audiovisual illusions. In the McGurk effect, auditory speech perception is altered by incongruent visual speech. In the Shams illusion, the number of seen flashes is altered by an incongruent number of heard beeps. The illusions were tested in 10-year-old children, whose musical aptitude was also assessed. The strength of the McGurk effect was not linked to musical aptitude. However, children with high musical aptitude scores had a weaker Shams illusion and a narrower temporal window of integration, suggesting that they integrate non-speech information more selectively than children with low musical aptitude. These findings imply that musical aptitude influences multisensory integration selectively for rapid non-speech events.

Music expertise shapes audiovisual temporal integration windows for speech, sinewave speech, and music
This psychophysics study used musicians as a model to investigate whether musical expertise shapes the temporal integration window for audiovisual speech, sinewave speech, or music. Musicians and non-musicians judged the audiovisual synchrony of speech, sinewave analogs of speech, and music stimuli at 13 audiovisual stimulus onset asynchronies (±360, ±300 ±240, ±180, ±120, ±60, and 0 ms). Furth...

Objectives: One of the most effective methods to describe speech disorders is the measurement of speech intelligibility. The speech intelligibility indicates the extent of acoustic signals that correctly speaker produces and hearer receives.

Objective: speech sound disorders are among the most common speech disorders in children. Non-speech oral motor exercises have long been used as a facilitative activity throughout therapy sessions for a wide variety of speech disorders by speech-language pathologists. But there are few empirical controlled data to evaluate its effectiveness. This study aimed at comparing the effects of therapeu...
متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
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 ...
