Identification of perceptual cues can be very helpful in almost all areas of speech signal processing. Recently, a new methodology called the 3-Dimensional-Deep Search and a visualized intelligible time-frequency computer-based model AI-gram have been introduced for research on the perceptual cues. Based on the technique, the acoustic cues for stop consonants [1], fricative consonants [2] and n...

Articulatory and perceptual aspects of fricative-stop coarticulation: a pilot study 1 Introduction This paper is concerned with the influence of a preceding fricative on the production and perception of a stop consonant. In a well-known series of experiments Repp showed that, when preceded by a fricative, an ambiguous stop acoustically halfway between /W/ and /N/ is identified differently depen...

Phonological development is often described as reflecting universal constraints, with some consonants or some consonant-vowel sequences assumed to be mastered earlier than others. Differences in order of acquisition are commonly ascribed to universal constraints on production or perception, reflecting biological specificities. Recent studies suggest, however, that language-specific patterns are...

Coronal harmony in Kinyarwanda causes alveolar fricatives to become postalveolar preceding a postalveolar fricative within a stem. Alveolar and postalveolar stops, affricates and palatals block coronal harmony, but the flap and non-coronal consonants are reported to be transparent. Kinematic data on consonant production in Kinyarwanda were collected using electromagnetic articulography. The mea...

Speakers can adopt a speaking style that allows them to be understood more easily in difficult communication situations, but few studies have examined the acoustic properties of clearly produced consonants in detail. This study attempts to characterize the adaptations in the clear production of American English fricatives in a carefully controlled range of communication situations. Ten female a...

The duration of speech segments as a function of position in utterances (initial, roedial, final) was studicd. In the first cxpedment seven Engl/sh speakers read nonsense utterances of the form "say a [bab], say a [bgbab], say a [babgb]," etc. Spectragrams were used to determine the duration of speech segments in the readings. Final syllables were found to be longer than nonfinal syllables. F/h...

Electropalatographic data on C-to-C coarticulatory e!ects were analyzed for consonant clusters composed of an extensive set of Catalan consonants, i.e., dentals (t), alveolars (n, dark l, s, trilled r), alveolopalatals (ʃ, V, E), palatals ( j) and velars (k). Regarding tongue dorsum coarticulation, results show that consonantal e!ects in CC clusters are more prominent than vocalic e!ects in VCV...

We examined the perception of Italian (IT) and Japanese (JP) consonant length contrasts (singleton vs geminate) in two groups of listeners: native speakers of IT and Australian English (OZ). Our preliminary results suggest that the IT listeners’ experience with singleton/geminate contrasts was more beneficial than the OZ listeners’ experience with vowel length contrasts in processing JP singlet...

Problem statement: Arabic speech recognition system is un-developed until today. By using people of non-Arab nationality, the set of frontal fricative of Arabic consonants are study as the earlier step to develop the recognition system for Malaysian. As most of the developed Arabic speech recognition system for Malaysian are rarely found. Approach: The characteristic of each of the phonemes wer...
