Three experiments were conducted to study relative contributions of speaking rate, temporal envelope, and temporal fine structure to clear speech perception. Experiment I used uniform time scaling to match the speaking rate between clear and conversational speech. Experiment II decreased the speaking rate in conversational speech without processing artifacts by increasing silent gaps between ph...

This paper concerns the effects of interrupting speech waves-turning them on and off intermittently or masking them with intermittent noise--upon their intelligibility. The effects were studied with various rates of interruption and with the speech left undisturbed various percentages of the time. Tests were conducted (1) with speech turned on and off in quiet, (2) with continuous speech masked...

PURPOSE In this research, the authors aimed to increase the analogy between Text Reception Threshold (TRT; Zekveld, George, Kramer, Goverts, & Houtgast, 2007) and Speech Reception Threshold (SRT; Plomp & Mimpen, 1979) and to examine the TRT's value in estimating cognitive abilities that are important for speech comprehension in noise. METHOD The authors administered 5 TRT versions, SRT tests ...

This study evaluated how hearing-impaired listeners perceive native (Swedish) and nonnative (English) speech in the presence of noise- and speech maskers. Speech reception thresholds were measured for four different masker types for each target language. The maskers consisted of stationary and fluctuating noise and two-talker babble in Swedish and English. Twenty-three hearing-impaired native S...

This study evaluates speech discrimination ability, as determined by a standard test of speech reception in noise, for one type hearing defect commonly found in military personnel, namely, noise-induced high-frequency hearing loss. Enlisted submariners with high-frequency hearing loss (average of 22, 45 and 60 decibels at 3, 4 and 6 kiloHertz, respectively) had poorer scores than a normal-heari...

Increased global interaction has led to increased communication between individuals with wide ranging linguistic experience. As a consequence, the ramifications of accent in speech production need to be better understood. It is plausible that differences in speech intelligibility due to accent type affect gross intelligibility in different ways. These differences may be differentially affected ...

Natural or synthetic speech is increasingly used in less-thanideal listening conditions. Maximising the likelihood of correct message reception in such situations often leads to a strategy of loud and repetitive renditions of output speech. An alternative approach is to modify the speech signal in ways which increase intelligibility in noise without increasing signal level or duration. The curr...

An acceptable noise level (ANL) procedure for measuring hearing aid directional benefit was compared with masked speech reception threshold (SRT) and front-to-back ratio (FBR) procedures. ANL is the difference between the most comfortable listening level and the maximum accepted background noise level while listening to speech. Forty adult subjects wearing their own binaural hearing aids were e...
