To provide new technological benefits to the mass people, nowadays, regional and local language recognition draws attention to the researchers. Similarly to other languages, Bangla speech recognition scheme is demandable. A formant is considered as the resonance frequency of vocal tract. Formant frequencies play an important role for the purpose of automatic speech recognition, due to its noise...

This study visualizes the glottal excitation in a temporally highly resolved estimate of the first formant. Instantaneous estimates during the glottal cycle of the frequency and bandwidth of the first formant closely follow the electroglottographic contour. This is demonstrated for phonation of an [a:] produced by one female patient with laryngeal dystonia. The observed contours in the F1 frequ...

An extensive developmental acoustic study of the speech patterns of children and adults was reported by Lee and colleagues [Lee et al., J. Acoust. Soc. Am. 105, 1455-1468 (1999)]. This paper presents a reexamination of selected fundamental frequency and formant frequency data presented in their report for ten monophthongs by investigating sex-specific and developmental patterns using two differ...

An adaptive time-domain postfiltering technique based on the synthesis LP filter factorisation is proposed. Information is gathered about the relation between the LP filter poles and formants for this factorisation. This technique shapes the main formant differently from the other formants. Pole locations representing the main formant are modified and optimum shaping constants for each 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...

A sinusoidal replica of a sentence evokes a clear impression of intonation despite the absence of the primary acoustic correlate of intonation, the fundamental frequency. Our previous studies employed a test of differential similarity to determine that the tone analog of the first formant is a probable acoustic correlate of sinusoidal sentence intonation. Though the typical acoustic and percept...

This paper proposes two new approaches for formant tracking using Fourier and wavelet ridges. The speech signal is decomposed into Time-Frequency representations issued from windowed Fourier transform and wavelet transform. Formant tracking is achieved by exploring ridges from time-frequency representation and imposing continuity constraints on formant trajectories. These approaches are validat...
