In skilled adult readers, transposed-letter effects (jugde-JUDGE) are greater for consonant than for vowel transpositions. These differences are often attributed to phonological rather than orthographic processing. To examine this issue, we employed a scenario in which phonological involvement varies as a function of reading experience: A masked priming lexical decision task with 50-ms primes i...

The purpese of the experiments reported was to establish a scale of hearing thresholds and intelligibility thresholds for Croatian sounds. The test material for the experiments consisted of all possible CV-type syllables. The result of the experiments show that the hearing thresholds depend on the vocalic syllable nucleus. The paradox is that the intelligibility thresholds for consonants are no...

We present a new feature-based method for estimating the speaking rate by detecting vowels in continuous speech. The features used are the modified loudness and the zerocrossing rate which are both calculated in the standard preprocessing unit of our speech recognition system. As vowels in general correspond to syllable nuclei, the feature-based vowel rate is comparable to an estimate of the le...

Infants' development of speech begins with a language-universal pattern of production that eventually becomes language specific. One mechanism contributing to this change is vocal imitation. The present study was undertaken to examine developmental change in infants' vocalizations in response to adults' vowels at 12, 16, and 20 weeks of age and test for vocal imitation. Two methodological aspec...

This paper proposes a new algorithm for Mandarin speech Consonant and Vowel (C/V) segmentation based on the fractal theory. The new method focuses on searching the transient region between the Consonant and Vowel parts in a Mandarin syllable that in general is a concatenation of a consonant followed by a vowel. The Multiscale Fractal Dimension Set (MFD) stands for the fractal dimensions at mult...

The objective and subjective classification of unvoiced stop consonants in varying vowel contexts were studied. The objective classification was based on auditory feature vectors obtained by warped linear prediction (WLP) and vector autoregressive (VAR) models for parameter trajectories. In the case of known vowel the unvoiced consonants were classified 98-100% correctly based on the auditory s...

The aim of the present study was to analyzed vowel and diphthong formant variation of a female patient diagnosed with amyotrophic lateral sclerosis (ALS) for 12 months using acoustic analysis. Monophthongs /a, i, u/ and diphthongs /h+ja+da/, /h+wi+da/, /h+ɰi+da/ were used for test. As the result of analysis, fundamental frequency and loudness declined with the progress of ALS characterized by d...

In Italian, length contrast is exploited in the consonant system. Previous articulatory studies have focused on the temporal organization of gestures in Italian geminates and on the lower lip kinematics of the singleton/geminate distinction, and have showed that the time interval between the nuclei of two successive syllables does not depend on the number of intervening consonants (Öhman‟s Vowe...

We investigated V-V hiatus through J-ToBI labeling and listening to whole phrases to estimate degree of discontinuity and to determine the exact boundary between two phrases if possible. Appropriate boundaries were found in most cases as the maximum perceptual score. Using electroglottography (EGG) and spectrogram, the acoustic phonological feature of these V-V hiatus was phrase-initial glottal...
