Analysis of English Nonsense Syllable Recognition in Noise

Experimental Evaluation of Improvement in Consonant Recognition for the Hearing- Impaired Listeners: Role of Consonant-vowel Intensity Ratio

One of the most common complaints expressed by individuals with hearing loss is the difficulty in understanding speech when listening in background noise. This paper highlights the importance of enhancement of an important acoustic attribute of clear speech -‘Consonant-Vowel intensity ratio’. A case for synthetic clear speech in the context of hearing impairment was developed. Consonant recogni...

Quantitative evaluation of lexical status, word frequency, and neighborhood density as context effects in spoken word recognition.

Listeners identified a phonetically balanced set of consonant-vowel-consonant (CVC) words and nonsense syllables in noise at four signal-to-noise ratios. The identification scores for phonemes and syllables were analyzed using the j-factor model [Boothroyd and Nittrouer, J. Acoust. Soc. Am. 84, 101-114 (1988)], which measures the perceptual independence of the parts of a whole. Results indicate...

Recognition of nonsense syllables by hearing-impaired listeners and by noise-masked normal hearers.

In the present study, speech-recognition performance was measured in four hearing-impaired subjects and twelve normal hearers. The normal hearers were divided into four groups of three subjects each. Speech-recognition testing for the normal hearers was accomplished in a background of spectrally shaped noise in which the noise was shaped to produce masked thresholds identical to the quiet thres...

Effects of prolonged lack of amplification on speech-recognition performance: preliminary findings.

The purposes of this investigation were two-fold: 1) to prospectively investigate the effect of prolonged lack of binaural amplification in the unaided ears of adults with bilaterally symmetrical sensorineural hearing impairment (BSSHI) fitted monaurally; and, 2) to prospectively investigate the effects of amplification on speech-recognition performance in the aided ears of monaurally and binau...
