The study was aimed to analyze the changes in acoustic parameters based upon age and gender effects and to obtain normal voice range profile (VRP) of adult male and female of three different age range. Total no. of 90 subjects were grouped into three groups as per their age (20-30, 40-50 and 60-70 years) consisting 15 males and 15 females in each group. All participants were native Bengla speak...

This study investigates the timing of stød, a type phonological nonmodal phonation related to creaky voice in Danish, relative syllable. Stød-bearing syllables are characterized by high fundamental frequency (F0) and modal at beginning syllable followed nonmodal, often low F0 towards end (the stød phase proper). However, these two phases each other has been debated. To investigate this, through...

The current study investigated spectral components of vowels that contribute to Mandarin and English sentence intelligibility. Sentences were processed to preserve various amounts of vowel information. Processing parameters ensured similar proportions of speech preserved between the two languages. In the first experiment, speech segments, primarily containing vocalic cues, were processed to fla...

This paper presents some preliminary results of a study on inter-speaker interaction of fundamental frequency of voice (F0) during dialogs. Simple question-answer type dialogs (in Japanese) were recorded and analyzed. The results revealed all three possible patterns of F0 interaction. In some cases, the two speakers' F0 converged as the dialog progressed, while in other cases they diverged; the...

The aim of this paper is to present an analysis on four basic emotions – anger, happiness, sadness, unemotional statethat are expressed during the speech, by using fundamental frequency curves (henceforth F0). In this experimental study, the sentences that can be expressed with four emotions were read by non-professional actors with four different emotions. The F0 curves for each utterance are ...

This abstract describes a method for the Multiple Fundamental Frequency (F0) Estimation and Tracking task in the Music Information Retrieval Evaluation eXchange (MIREX) 2007. The method is called Harmonic Temporal Structured Clustering (HTC), which is a kind of constrained Gaussian Mixture Model (GMM) estimation using EM algorithm. It can jointly extract F0, intensity, onset, duration of each u...

This paper is a progress report on a project in linguistically based automatic speech recognition, The domain of this project is English intonation. The system I will describe analyzes fundamental frequency contours (F0 contours) of speech in terms of the theory of melody laid out in Pierrehumbert (1980). Experiments discussed in Liberman and Pierrehumbert (1983) support the assumptions made ab...

In this paper, we present recent developments in the characterizat ion of healthy and pathologic cries of newborns. We have identified and quantified acoustic characteristics that appear the most relevant in differentiating between pathological and healthy cries; such as fundamental frequency (F0), irregularity of F0 and presence of hyper-phonic modes. The results obtained are very encouraging,...

This paper presents a study on the control of fundamental frequency (F0) in Cantonese text-to-speech (TTS) systems. The surface F0 contour of an utterance is considered as the combination of tone-related local components and phrase-level long-term variation. A novel method of F0 normalization has been developed to effectively separate them. Statistical analysis is performed for the phrase curve...

Previous studies of infant cry acoustics and their perceptual significance have remained inconclusive as to the graded nature of cry production and perception and to the exact role and importance of particular acoustic features. In this study, a set of infant cries were digitally analyzed and resynthesized to form natural-sounding cries with varying fundamental frequency (F0), degrees of jitter...
