Recent studies have shown that talkers implicitly imitate/accommodate the phonetic properties of recently heard speech [1, 2]. However, it has also been shown that this phonetic imitation effect is not an automatic process [3, 4]: in [3], the artificially lengthened VOT on /p/ was imitated in a non-shadowing task, while shortened VOT (which could jeopardize phonemic contrast) was not imitated, ...

This paper presents the first description of vowel devoicing in Quechua. The characteristics of the process as well as the environments most conducive to its occurrence are reported based on an analysis of 4062 vowels extracted from interviews with 16 speakers of the Cusco Collao dialect. Patterns of Quechua vowel devoicing appear to be generally consistent with the gestural overlap model that ...

In this paper, we put forward an information theoretic definition of the redundancy that is observed across the sound inventories of the world’s languages. Through rigorous statistical analysis, we find that this redundancy is an invariant property of the consonant inventories. The statistical analysis further unfolds that the vowel inventories do not exhibit any such property, which in turn po...

Investigations have been made on the perceptual and acoustic properties of individual phonemes in continuous speech for different speaking rate. Fifteen short sentences spoken by four male speakers have been used as the test material. Each speaker has been asked to pronounce the sentences with three different rates: normal, first and slow. For perceptual experiment, individual CV-syllables have...

Vowel duration has been an issue in the study of Civili. Although minimal pairs based on vowel duration can be established at both perceptual and physical level, vowel lengthening still occurs in the context of voiced consonants in the language. A comparison between a measured physical duration and an experimentally perceived duration confirms the phonemic distinctiveness of vowel length and in...

It is widely claimed that close vowels in Japanese are devoiced when they occur between voiceless consonants. In this paper, voiceless vowels are represented symbolically as [V-] and voiced vowels as [V+]. The patterns of linguopalatal contact during C[V-]C units and the corresponding C[V+]C units are examined using the method of electropalatography (EPG). Our results show that C[V-]C units and...

The well-studied phenomenon of vowel lengthening before tense sonorants in Modern Irish (Ó Siadhail 1989, Ó Siadhail and Wigger 1975, Ó Baoill 1979), exemplified in (1), is now well understood as a compensatory process (see for example Ní Chiosain 1991). Tense or long sonorants (L, L', R', N, N', m) trigger vowel lengthening and/or diphthongization. What is not clear about this phenomenon is th...

Japanese vowel devoicing was investigated from the viewpoint of perception, an approach which has not been taken in any previous studies. It appears in some dialects of Japanese, including Tokyo dialect. Three tests, a vowel preference test, a same/different test, and an inter-stimulus interval effect test were performed. In the vowel preference tests, 46.3% of devoiced vowel dialects speakers ...
