Two experiments showed that continuity of the pitch contour is an important perceptual indicator that a formant pattern comes from a single speech source. Subjects listened to repeatedly played formant patterns that changed smoothly between two vowels. When the pitch was a monotone, these patterns were heard as containing semivowels and liquid consonants; but when a discontinuous, steplike pitc...

Exaggeration of the vowel space in infant-directed speech (IDS) is well documented for English, but not consistently replicated in other languages or for other speech-sound contrasts. A second attested, but less discussed, pattern of change in IDS is an overall rise of the formant frequencies, which may reflect an affective speaking style. The present study investigates longitudinally how Dutch...

The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay female children had higher formant frequencies than those of their male counterparts. However, no significant differences in all four formant ...

The aim of this paper is to design a closed-set text-independent Speaker Identification system using average pitch and speech features from formant analysis. The speech features represented by the speech signal are potentially characterized by formant analysis (Power Spectral Density). In this paper we have designed two methods: one for average pitch estimation based on Autocorrelation and othe...

Comodulation of masker components can have opposite effects on detection performance: In a simple tone-innoise task, by adding comodulated masker components outside of the critical band, the performance of tone detection is improved. This effect has been termed Comodulation Masking Release (CMR, [2]). Otherwise, if comodulated flanking bands are presented in a modulation detection task, the per...

Linear prediction (LP) coe cients are used to describe the formant structure of a speech waveform. Many factors contribute to the frame-to-frame uctuation of these parameters. These variations adversely a ect the performance of the LP quantizer and the quality of the synthesized speech. For voiced speech, e cient coding of the pitch pulses at the output of the inverse formant lter relies on the...

Accurate measurement of formant frequencies is important in many studies of speech production and perception. The mapping of formant frequencies from cepstra coefficients by Broad and Clermont (1989) is an important evolution in formant estimation techniques from previous studies. This method also holds significant potential in estimating formant frequencies of sung vowels due to its improved r...

Successful speech perception in real-world environments requires that the auditory system segregate competing voices that overlap in frequency and time into separate streams. Vowels are major constituents of speech and are comprised of frequencies (harmonics) that are integer multiples of a common fundamental frequency (F0). The pitch and identity of a vowel are determined by its F0 and spectra...

Due to a constantly increasing amount of speech data that is stored in different types databases, voice privacy has become major concern. To respond such concern, researchers have developed various methods for speaker de-identification. The state-of-the-art solutions utilize deep learning which can be effective but might unavailable or impractical apply for, example, under-resourced languages. ...

In natural speech, there is a moderate correlation between the fundamental frequency and formant frequencies across talkers. The present study used a high-quality vocoder to manipulate these properties and determine their contribution to perceived naturalness and voice gender. The stimuli were re-synthesized sentences spoken by two adult males and two adult females. Scale factors were chosen fo...
