SOME ISSUES IN RESEARCH ON THE PERCEPTION OF STEADY-STATE VOWELS Vowel identification and spectral slope Eva Agelfors and Mary Graslund 10 Why does [a] change to [:l] when F O is increased?: Interplay between harmonic structure and forman frequency in the perception of vowel quality Ake Floren 13 Analysis and prediction of difference limen data for formant frequencies Lennart Nord and Eva Sventelius 24 Vowel identification as a function of increasing fundamental frequency Elisabeth Tenenholtz 38 Essentials of a psychoacoustic model of spectral matching Hartmut TraunmOlier 49 3. ON THE PERCEPTUAL ROLE OF DYNAMIC FEATURES IN THE SPEECH SIGNAL Interaction between spectral and durational cues in Swedish vowel contrasts Anette Bishop and Gunilla Edlund 64 On the distribution of [h] in the languages of the world: Is the rarity of syllable final [h] due to an asymmetry of backward and forward masking? Eva Holmberg and Alan Gibson 68 On the function of formant transitions I. Formant frequency target vs. rate of change in vowel identification 83 II. Perception of steady vs. dynamic vowel sounds in noise 92 Karin Holmgren 83 Artificially clipped syllables and the role of formant transitions in consonant perception Hartmut TraunmOlier 105
