Voices can be characterized by their fundamental frequency as well as by speech timbre characteristics, such as formant frequencies. While infants’ responses to fundamental frequency characteristics are well established, very little is known about how infants respond to changes in formant frequencies. This study tested whether 6-month-old infants prefer listening to speech with raised formant f...

this study focuses on one particular sound change common in conversational speech, in which coronal nasal consonants undergo place assimilation toward the following syllable- or word-initial labial consonants. f2 and f3 formant frequency measurements were taken from, and compared between words involving the sequences /vnb/ and /vmb/ across syllable boundary as well as word boundary in assimilat...

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 ...

speech emotion can add more information to speech in comparison to available textual information. however, it will also lead to some problems in speech recognition process. in a previous study, we depicted the substantial changes of speech parameters caused by speech emotion. therefore, in order to improve emotional speech recognition rate, in a first step, the effects of emotion on speech par...

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...

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...

Measuring formant frequencies in speech signals is indispensable for the search and technically problematic. Accurate measurement of formant frequencies is important in many studies of speech perception and production. Unfortunately, there is no totally effective method to allow good valuations of these frequencies. This paper presents a comparative study of two techniques of speech parameteriz...

This paper proposes a method of predicting the formant frequencies of a frame of speech from its mel-frequency cepstral coefficient (MFCC) representation. Prediction is achieved through the creation of a Gaussian mixture model (GMM) which models the joint density of formant frequencies and MFCCs. Using this GMM and an input MFCC vector, a maximum a posteriori (MAP) prediction of the formant fre...
