Variable Perception of White Noise in Ambiguous Phonetic Contexts
Vowel normalization
Producing Speech
Cross-sectional tongue shape and linguopalatal contact patterns in [s], [∫], [f], and [1]
Some Acoustic and Physiological Observations on Diphthongs
This paper presents an analysis of some articulatory properties of (Dutch) diphthongs, attempting to correlate articulatory inferences based on perceptual and acoustic data with more direct physiological measurements (recordings of EMG activity). Evidence is presented that supports a distinction between "genuine" and "pseudo" diphthongs: the two classes appear to differ (1) in openness and advancement at their onsets and offsets, (2) in the harmo…
On Defining the Vowel Duration That Cues Voicing in Final Position
Most investigations into the perceptual relevance of vowel duration have employed patterns of synthetic speech in which only the steady-state portions of syllables have been used as the variable. The experiments reported here were designed to discover if CV transitions are also included by the listener in determining the effective duration of the "vowel." More specifically, they measured the contribution of syllable-initial formant transitions to…
Acoustic cues for a fricative-affricate contrast in word-final position
Voicing-conditioned durational differences in vowels and consonants in the speech of three-and four-year old children

Tongue Position in Rounded and Unrounded Front Vowel Pairs
Traditional articulatory descriptions of front rounded and unrounded vowel pairs have assumed that tongue height is the same for the members of the pairs /i-y/, /e-ø/, and /ε-œ/. The electromyographic, articulatory synthetic, and acoustic investigations carried out in this study indicate that, in Dutch, the rounded member of the pairs /i-y/ and /e-ø/ was centralized. In the /ε-œ/ pair, however, the rounded vowel bears a different relationship to …

The physiological control of durational differences between vowels preceding voiced and voiceless consonants in English
Preceding Vowel Duration as a Cue to the Perception of the Voicing Characteristic of Word-Final Consonants in American English
A number of studies in the literature have stated that the duration of a vowel is a significant cue to the voicing characteristic of the consonant that follows it. The present study investigated the effect of varying preceding vowel duration upon the perception of word-final stops, fricatives, and clusters in synthetic speech. A variety of minimal CVC (C) pairs was synthesized and the vowel of each was varied over a range of values derived from d…
