Vowel identification in noise using consonant-vowel-consonant (CVC) logatomes was used to investigate a possible interplay of speech information from different frequency regions. It was hypothesized that the periodicity conveyed by the temporal envelope of a high frequency stimulus can enhance the use of the information carried by auditory channels in the low-frequency region that share the sam...

Standard Austrian German, which distinguishes eight front vowels, exploits two front constriction locations for distinguishing these vowels, a pre-palatal and a palatal one. However, the pre-palatal location is acoustically unstable, and, consequently, phonologically undesirable. The existence of a sound change which neutralizes the /i/ and /ɪ/ vowels in a first step and shifts the constriction...

Vowel devoicing is a common phonological process in many languages and typically involves high vowels and schwa. High vowels and schwa are inherently short (Bell, 1978; Dauer 1980) and the process usually occurs when the vowels are either adjacent to, or surrounded by, voiceless consonants, during which the glottis is fully open. It is thought that vowel devoicing is a consequence of articulato...

This article investigates using real-time magnetic resonance imaging the vocal tract shaping of 5 soprano singers during the production of two-octave scales of sung vowels. A systematic shift of the first vocal tract resonance frequency with respect to the fundamental is shown to exist for high vowels across all subjects. No consistent systematic effect on the vocal tract resonance could be sho...

The purpose of this paper is to introduce a speech synthesis system based on speech production process. We have developed a GUI-based speech synthesis system that produces steady and continuous vowels. For the continuous vowels, a response pattern of the cascaded first-order systems is used for describing smooth change in vocal tract configuration. In this study, the speech synthesis system was...

The present article presents a study of the raising of overlong mid vowels in Estonian dialects. Long mid vowels of South Estonian dialects (Mulgi, Tartu and Võru) have split into full-long mid vowels (Q2) and into overlong raised mid vowels (Q3). Raising of mid vowels also characterises West Estonian dialects. The formant values of raised mid vowels of Võru and Mulgi show that they are much hi...

An acoustic impedance spectrometer was used to measure the frequencies R1 and R2 of the first two resonances of the vocal tract. The measurement was made just outside the mouth, in parallel with the free field, using a new technique that provides precise information about the acoustic response of the vocal tract in real time. Values measured for native speakers for a particular vowel were used ...

To produce near-native American English (AE) vowels, Japanese speakers must extend their five vowel system with at least six new vowels. Three experiments have been conducted to acquire both perceptual and acoustic measures about Japanese accented English (JE)vowels. Six non-back vowels of AE in several phonetic environments were recorded from four Japanese male talkers with moderate English sk...
