Improving the intelligibility of dysarthric speech
Speech Communication, 2007Dysarthria is a speech motor disorder usually resulting in a substantive decrease in speech intelligibility by the general population. In this study, we have significantly improved the intelligibility of dysarthric vowels of one speaker from 48% to 54%, as evaluated by a vowel identification task using 64 CVC stimuli judged by 24 listeners. Improvement

Journal of the Acoustical Society of America, 2016
Older adults, even those with normal or near-normal audiograms, report greater subjective listening difficulty in everyday life compared to younger adults. However, their difficulties are not well predicted from pure-tone or speech audiometry in quiet or noise.

Intelligibility of synthetic speech in the presence of interfering speech
Speech Communication, 1989Standard articulation tests are not always sensitive enough to discriminate between speech samples which are of high intelligibility. One can increase the sensitivity of such tests by presenting the test materials in noise. In this way, small differences in intelligibility can be magnified into large differences in articulation scores.

Automatic enhancement of speech intelligibility
2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002This paper presents a speech signal transformation which slows down speech signals selectively and enhances some important acoustic cues. This transformation can be used not only for hearing aids but also for second language acquisition by facilitating oral comprehension. Selective slowing down relies on the use the TD-PSOLA synthesis method.

Intelligent Processing of Stuttered Speech
Journal of Intelligent Information Systems, 2003The process of counting stuttering events could be carried out more objectively through the automatic detection of stop-gaps, syllable repetitions and vowel prolongations. The alternative would be based on the subjective evaluations of speech fluency and may be dependent on a subjective evaluation method.

The pretherapy speech intelligibility of a glossectomee
Journal of Communication Disorders, 1974Abstract The speech intelligibility of a glossectomee was established prior to the initiation of therapy. It was found that while quantifiable intelligibility was only moderate, confusions were well ordered into classes. The perceptual characteristics of the glossectomee's speech were not qualitatively different from those reported by others ...

The intelligibility of speech with “holes'’ in the spectrum
The Journal of the Acoustical Society of America, 2002The intelligibility of speech having either a single “hole” in various bands or having two “holes” in disjoint or adjacent bands in the spectrum was assessed with normal-hearing listeners. In experiment 1, the effect of spectral “holes” on vowel and consonant recognition was evaluated using speech processed through six frequency bands, and synthesized ...

Interaural alternation and speech intelligibility
The Journal of the Acoustical Society of America, 1974The intelligibility of interaurally alternated speech was measured by two methods: shadowing and subjective estimation. A passage of connected discourse was recorded at two speaking rates, normal (135 wpm) and fast (194 wpm). Shadowing scores and estimations of intelligibility for normal-rate speech were nearly 100% at eight rates of alternation ...

The speech interface for intelligent robots
2010 International Conference on Machine Learning and Cybernetics, 2010An appropriate interface is not only to providing a better controlled environment, but also increasing the willing of the using by operator. This paper presents a robot speech user interface's design. The system is based on a continuous Gaussian Hidden Markov model as a basis for using Viterbi algorithm in the speech of modeling and identification ...

Measuring up to speech intelligibility
International Journal of Language & Communication Disorders, 2013AbstractImprovement or maintenance of speech intelligibility is a central aim in a whole range of conditions in speech–language therapy, both developmental and acquired. Best clinical practice and pursuance of the evidence base for interventions would suggest measurement of intelligibility forms a vital role in clinical decision‐making and monitoring ...
