Available in PDF, EPUB and Kindle. Book excerpt: Objectives: To explore the efficacy of a new digital signal processing strategy (DSP) by comparing speech intelligibility in noise measures across different sound strategies. Introduction: Hearing aids are of limited benefit for the perceptual consequences that arise from a loss of frequency selectivity. By eliminating inaudible sound energy, and reducing ‘masking’ noise around speech peaks based on individual spreading functions, the new DSP effectively acts as a masking suppressor to enhance spectral contrast between speech peaks and dips. It is hypothesised that a combination of wide dynamic range compression (WDRC) and DSP will show greatest improvement in objective measures of speech intelligibility in noise. It is also hypothesised that no difference in subjective sound quality will be found. Methods: Twenty current hearing aid wearers (60-75 years) with symmetrical, normal/mild, sloping to a moderate/severe sensorineural hearing loss were recruited. Treble increase at low levels (TILL) prescription templates were used to achieve an approximation of real-ear, prescribed WDRC. An estimate of critical bandwidth (CB) was obtained using a consonant-nucleus-consonant (CNC) in white-noise tournament with different DSP types. Objective (QuickSINTM) and subjective (soundscape quality) speech intelligibility in noise results were compared across four sound strategies: No-Processing, DSP, TILL and DSP + TILL. Results: DSP type 1.0 had the highest CNC in white-noise phoneme and word score overall, but was not significantly different from No-Processing. Both DSP and DSP + TILL had significantly higher mean total QuickSINTM scores than No-Processing. Mean DSP + TILL QuickSINTM scores at +5 dB signal to noise ratio (SNR) were significantly higher than No-Processing. DSP + TILL also had a significantly higher mean score at +20 dB SNR than No-Processing or TILL. No significant difference in sound quality between strategies was found. Conclusions: This study suggests speech intelligibility can be enhanced in background noise using the new DSP either alone, or in combination with WDRC. The method used to estimate individual CB could be implemented clinically. The new DSP could also be incorporated at the front-end of WDRC hearing aid processing. Future directions include the possibility of integrating a more accurate, objective measure of auditory filter characteristics with the new DSP, and exploring the effects of an acclimatisation period on speech intelligibility in noise.

Download or read book Speech Intelligibility and Quality Resulting from an Ideal Quantized Mask written by Jordan L. Vasko and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Speech recognition in noise presents a significant challenge for individuals with hearing loss, and current technologies to remedy this problem are limited. Recently developed machine learning algorithms have, however, proved to be promising solutions to this problem, as they have been able to segregate speech from noise to significantly improve its intelligibility for both normal-hearing and hearing-impaired listeners. The following paper introduces a novel segregation method to be employed by such machine-learning algorithms. The intelligibility and quality of speech-noise mixtures processed via this method were evaluated for normal-hearing listeners. The proposed approach was shown to produce speech intelligibility and quality that were comparable to those produced by the best current technique. Because this approach also has characteristics that may make implementation easier, it potentially represents a better approach than other existing methods.

Download or read book Noise Reduction in Speech Processing written by Jacob Benesty and published by Springer Science & Business Media. This book was released on 2009-04-28 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise is everywhere and in most applications that are related to audio and speech, such as human-machine interfaces, hands-free communications, voice over IP (VoIP), hearing aids, teleconferencing/telepresence/telecollaboration systems, and so many others, the signal of interest (usually speech) that is picked up by a microphone is generally contaminated by noise. As a result, the microphone signal has to be cleaned up with digital signal processing tools before it is stored, analyzed, transmitted, or played out. This cleaning process is often called noise reduction and this topic has attracted a considerable amount of research and engineering attention for several decades. One of the objectives of this book is to present in a common framework an overview of the state of the art of noise reduction algorithms in the single-channel (one microphone) case. The focus is on the most useful approaches, i.e., filtering techniques (in different domains) and spectral enhancement methods. The other objective of Noise Reduction in Speech Processing is to derive all these well-known techniques in a rigorous way and prove many fundamental and intuitive results often taken for granted. This book is especially written for graduate students and research engineers who work on noise reduction for speech and audio applications and want to understand the subtle mechanisms behind each approach. Many new and interesting concepts are presented in this text that we hope the readers will find useful and inspiring.
