The intelligibility of speech sysnthesis systems that are available nowadays is usually high enough to enable comparisons between different synthesis systems based on the speech quality. However, in some situations, like a civil aircraft cockpit, the acoustic environment may be such that intelligibility is a discriminating factor between systems. In this paper we propose a methodology for compa...

BACKGROUND Hearing loss is one of the common complaints of diabetics. The aim of this study was to evaluate the hearing status of diabetic patients in Babol, North of Iran. METHODS The hearing status of 50 type 2 diabetic patients (case group) and 50 healthy individuals (control group) were evaluated from October 2011 to September 2012. Audiometry was done with the frequencies of 250, 500, 10...

OBJECTIVE The objective of the study was to implement a previously developed automatic speech-in-noise screening test by telephone (Smits, Kapteyn, & Houtgast, 2004), introduce it nationwide as a self-test, and analyze the results. DESIGN The test was implemented on an interactive voice response system, which can handle multiple lines. The test measures the speech reception threshold in speec...

In this paper, the effects of multipacket reception (MPR) capability on the capacity of wireless networks with regular structures are analyzed. Under uniform traffic and minimum connectivity, the maximum stable packet generation rate for the MPR Manhattan networks is obtained. For a network of size N , it is shown that the capacity is K1/ √ N , and adding MPR affects the coefficient K1 of a non...

Demonstration of successful outcomes from use of a sensory device by individuals with hearing loss depends to a large extent on quantifiable improvements in auditory performance. Quantifiable improvements are typically characterized by speech perception outcomes, which involve speech awareness/detection, reception, discrimination, identification or recognition of speechtype materials (e.g., pho...

Recent psychophysical studies suggest that human listeners do not segregate concurrent sounds by grouping frequency regions that have a common interaural time difference (ITD). However, such an approach is adopted by most computational auditory scene analysis (CASA) systems that use binaural cues. Here, we propose a CASA system that separates a target speech signal from a noise interferer, but ...

OBJECTIVE To introduce and verify an algorithm designed to administer adaptive speech-in- noise testing to a specified reliability at selectable points on the psychometric function. DESIGN Speech-in-noise performances were measured using BKB sentences presented in diffuse babble-noise, using morphemic scoring. Target of the algorithm was a test-retest standard deviation of 1.13 dB within the ...
