Consonant repetition ("reduplication") predominates in #CVC sequences in babbling and early words, gradually giving way to consonant variation ("variegation") with a "Fronting" pattern whereby the first consonant has a more anterior place of articulation than the second. The various reduplicative patterns are primarily attributed to a "Frame" consisting of rhythmic mandibular oscillation. Evide...

Intra-gestural and inter-gestural coordination in German word-initial consonant clusters /kl, kn, ks, pl, ps/ is investigated in four speakers by means of EMA as a function of segmental make-up and prosodic variation, i.e. prosodic boundary strength and lexical stress. Segmental make-up is shown to determine the extent of articulatory overlap of the clusters, with /kl/ exhibiting the highest de...

In Tokyo Japanese, vowel devoicing is a common process, that leads to the reduction of high, unstressed vowels ( and ) between unvoiced consonants. This article investigates to what extent native Japanese speakers (L1) learning German as foreign language (L2) show a strong tendency to produce these vowels in the foreign language as devoiced, too. Furthermore, the question is addressed whe...

Mismatch negativity (MMN) was used to investigate the processing of cluster and noncluster initial consonants in consonant-vowel syllables in the human brain. The MMN was elicited by either syllable with cluster or noncluster initial consonant, phonetic contrasts being identical in both syllables. Compared to the noncluster consonant, the cluster consonant elicited a more prominent MMN. The MMN...

The present study explores the effects of non-linguistic experiences on biases for linguistic judgments, specifically consonant deletion patterns. When two adjacent consonants come into contact as a result of morphological concatenation, many languages will delete the first consonant (e.g., /bepdok/ becomes /bedok/). Speakers of these languages (as well as English speakers) prefer deletion of t...

The most common complaint of older hearing impaired (OHI) listeners is difficulty understanding speech in the presence of noise. However, tests of consonant-identification and sentence reception threshold (SeRT) provide different perspectives on the magnitude of impairment. Here we quantified speech perception difficulties in 24 OHI listeners in unaided and aided conditions by analyzing (1) con...

This paper proposes a phonological analysis for vowel devoicing in Tokyo Japanese using the framework of Optimality Theory (Prince and Smolensky, 1993). Generally speaking, in Japanese the high vowels /i, u/ are devoiced when they occur between two voiceless consonants. However, there are some contexts where such a simple generalization does not hold, e.g., so called “word-final devoicing” and ...

The purpose of this study was to evaluate the efficiency of three acoustic modifications derived from clear speech for improving consonant recognition by young and elderly normal-hearing subjects. Percent-correct nonsense syllable recognition was measured for four stimulus sets: unmodified stimuli; stimuli with consonant duration increased by 100%; stimuli with consonant-vowel ratio increased b...

Investigation of spontaneous speech corpora has shown that vowel devoicing in Japanese is a statistical phenomena. However, factors behind vowel devoicing have not been fully studied. In addition, there have been no studies that specifically examined pre-pausal vowel devoicing. In this paper, we investigate vowel devoicing in the pre-pausal position, in particular, vowel devoicing occurring at ...
