Noisy Speech Intelligibility Enhancement
This paper addresses the study of the speech intelligibility enhancement. The speech model, noise sources, perceptual aspects of speech, and performance evaluation are reviewed. The intelligibility enhancement system based on spectral subtraction technique is investigated. Spectral density estimation device based on the algorithm of smoothed periodograms is analysed. Determination of the silenc...
متن کاملEffects of Urgent Speech and Preceding Sounds on Speech Intelligibility in Noisy and Reverberant Environments
Public-address (PA) announcements are used to convey emergency information; however, noise and reverberation sometimes make announcements in public spaces unintelligible. Therefore, the present study investigated how combinations of speech spoken in an urgent style and preceding sounds affect speech intelligibility and perceived urgency in noisy and reverberant environments. Sentences were spok...
متن کاملSpeech Intelligibility and the Detection of Auditory Alarms and Warnings in Noisy Industrial Environments
Issues affecting speech intelligibility and audibility/detectability of auditory displays in the industrial workplace will be presented. Topics will include design guidelines, standards, and relevant research from the literature. Examples of experimental results will be presented from research conducted in Virginia Tech’s Auditory Systems Laboratory.
متن کاملPredicting speech intelligibility in conditions with nonlinearly processed noisy speech
The speech-based envelope power spectrum model (sEPSM; [1]) was proposed in order to overcome the limitations of the classical speech transmission index (STI) and speech intelligibility index (SII). The sEPSM applies the signal-tonoise ratio in the envelope domain (SNRenv), which was demonstrated to successfully predict speech intelligibility in conditions with nonlinearly processed noisy speec...
