The purpose of this study was to provide information concerning the possible early effects of smoking on measures of respiratory capacity and control in young adult female smokers vs. nonsmokers. In particular, maximum performance test results (vital capacity and maximum phonation time) and measures of air pressures and airflows during voiceless,…

Two tracheoesophageal speakers experienced in use of the tracheostoma valve (TSV) produced speech samples varying with location of contrastive stress, sentence intonation, and use of TSV. Listeners (n=34) found that TSV-use reduced speaker ability to signal suprasegmentals; however, locus of the suprasegmentals, particularly stress placement,…

This study analyzed production of a long vowel sound within Finnish words by normal or dysphonic voices, using the Self-Organizing Map, the artificial neural network algorithm of T. Kohonen which produces two-dimensional representations of speech. The method was found to be both sensitive and specific in the detection of dysphonia. (Author/JDD)
