“…Clear speech is related to other goal-oriented modes of speech production, such as infant-directed speech, Lombard speech, and computer-directed speech, in which talkers "adjust" their output to meet the demands of their target audience or the communicative situation ͑Junqua, 1993; Skowronski and Harris, 2005;Kuhl et al, 1997;Fernald, 2000;Liu et al, 2004͒. Clear speech also shares characteristics with variation due to prosodic strengthening and fast-to-slow rate modifications ͑Cole et de Jong, 1995;Cho, 2005;Hirata, 2004;co-workers, 1988, 1989͒. These modifications can all be viewed as involving changes from hypo-to hyperarticulation ͑H&H Theory, Lindblom, 1990͒ with respect to articulatory and acoustic features such as reduction of target undershoot and enhancement of phonemic contrasts as seen in, for instance, expanded vowel spaces and increased vowel length and consonant voicing contrasts.…”

This study investigated the effect of hyperarticulated, intelligibility-enhancing clear speech on temporal characteristics as reflected in number, durations, and variability of consonant and vowel intervals in sentence-and paragraph-length utterances. The results of sentence-in-noise listening tests showed a consistent clear speech intelligibility gain across the utterances of varying complexity indicating that the talkers successfully maintained clear speech articulatory modifications throughout longer stretches of speech. The acoustic analysis revealed that some temporal restructuring accompanied changes in speaking style. This temporal restructuring was observed in the insertion of consonant and vowel segments that were dropped or coarticulated in conversational speech and in an increase in the number of prosodic phrases for clear speech. Importantly, coefficients of variation ͑variation of consonantal and vocalic intervals normalized for changes in speaking rate͒ for both consonantal and vowel intervals remained stable in the two speaking styles. Overall, these results suggest that increased intelligibility of clear speech may be attributed to prosodic structure enhancement ͑increased phrasing and enhanced segmentability͒ and stable global temporal properties.

“…Although Yi reported the effects of speaking rate on the vowel length distinction for native and non-native speakers of Japanese [13] and Hirata for native Japanese speakers [14], this paper attempts to clarify the durational structure of the special morae in Japanese (first part of the geminate consonants and second part of the long vowels) in more specific ways and to compare the mora timing organization of Chinese-speaking subjects of Japanese with that of native Japanese subjects.…”

“…Hypothesis I is interpreted as an 'interaction of position and rate' statistically. In CV 1 V 2 words, SS 1 was significantly shorter than SS 2 (F(1,5)=12.90, 11 Proportions were included since it has been noted that durational proportion in word is an 'invariant' property of vowel in Japanese and Swedish vowel length contrast, which is little affected by speech rate (Hirata 2004 andSegerup 2000). Hypothesis II states that a rate effect will be greater in high vowels than nonhigh vowels.…”

In lieu of an abstract, here is a brief excerpt:Typological patterns in synchronic data, for example, the question of why pattern A is more frequent than B across languages, have been one of the most important issues in linguistics, in particular in phonology. Ohala (1993) seeks the answer in human articulatory and/or auditory mechanisms. If a phonetic ‘perturbation’ is not corrected properly in perception, a hypo-correction could occur and it could result in a sound change. In this model, typological patterns are assumed to reflect the very variation in ordinary speech. Two crosslinguistic asymmetries in hiatus reso-lution are the main concerns in this paper. Casali (1996) and Rosenthall (1997) present positional and height asymmetries. They take another approach to the ty-pological patterns in that they suggest universal constraints and rankings to ac-count for the asymmetries in the framework of Optimality Theory (Prince and Smolensky 1993). Crosslinguistically, hiatus resolution such as vowel deletion or gliding is more likely to occur in V1 and high vowels than in V2 and non-high vowels. If these patterns result from human articulatory and auditory mechanisms as Ohala (1993) argues, it would be expected that the production of vowel se-quences will show a pattern of phonetic variation, which is similar to the phono-logical processes. As the first step, a set of acoustic data on Korean hiatus is pre-sented in this paper. The results will show that V1 in hiatus is consistently shorter than V2, which corresponds to the positional asymmetry in Casali (1996). As for the height asymmetry, it will be reported that high vowels are more reduced in fast speech, compared to their durations in slow speech.
