PURPOSE Statistical studies conducted in various languages on both infants and adults have revealed an intersyllabic preference for initiating words with a labial consonant-vowel-coronal consonant sequence. Speech motor constraints have been proposed to explain this so-called labial-coronal effect. This study was designed to test for a possible perceptual correlate of the labial-coronal effect ...

Speaking rate in general, and vowel duration more specifically, is thought to affect the dynamic structure of vowel formant tracks. To test this, a single, professional speaker read a long text at two different speaking rates, fast and normal. The present project investigated the extent to which the first and second formant tracks of eight Dutch vowels varied under the two different speaking ra...

A central challenge for articulatory speech synthesis is the simulation of realistic articulatory movements, which is critical for the generation of highly natural and intelligible speech. This includes modeling coarticulation, i.e., the context-dependent variation of the articulatory and acoustic realization of phonemes, especially of consonants. Here we propose a method to simulate the contex...

The distribution of geminate obstruents in Japanese loanwords appears very complex. Some consonants are more prone to gemination than others, on the one hand, and one and the same consonant is more likely to geminate in some phonological contexts than in others, on the other hand. This paper tackles these problems by considering the relationship between consonant gemination in native words and ...

We show the perception of Canadian French (CF) vowels by Canadian English (CE) listeners and test a cue-weighting hypothesis to explain the attested assimilation patterns. Five CF vowels, /i, y, u, , æ/, and three allophonic variants, [, , ], were examined. The listeners completed a native-language identification task with goodness of fit judgments. We found that most French vowels were ide...

In Lab #7, we looked at designing low-order digital filters to model human vowel production. Why is this a useful technique? We argued that such models were useful for studying speech production and the like. However, there are more practical, applied reasons for doing this. Suppose that we want to perform speech recognition and determine which vowel is being said. A system would be hard presse...

The neural basis of speech recognition and, more generally, sound processing is not well understood. A simple subset of the task of speech recognition, learning to categorise vowel sounds, provides some insights into the more general problems. A simulated neural system that performs this task is described. The system is based on relatively accurate fatiguing leaky integrate and fire neurons, an...

This study explored whether an identity-matching-based stimulus equivalence procedure could be used to teach vowel and consonant stimulus classes to 2 adolescent females with moderate mental retardation. Delayed match-to-sample trials presented a compound sample stimulus consisting of printed letters and a spoken word ("vowel" or "consonant"). The correct comparison stimulus matched only one of...

Vowel prolongation is often used to evaluate disordered voice production. In light of previous findings showing that co-articulation has significant influence on laryngeal function measures, the practice of using prolonged vowels to represent a speech sample is questioned. To test whether disordered and normal voice during vowel production is generalizable to connected speech, three speaking ta...
