PURPOSE To determine the relative importance of acoustic parameters (fundamental frequency [F0], formant frequencies [FFs], aperiodicity, and spectrum level [SL]) on voice gender perception, the authors used a novel parameter-morphing approach that ...

Formant-based acoustic features for cow's estrus detection in audio surveillance system
Advanced Video and Signal Based Surveillance, 2014In this paper, we developed an optimal formant feature subset algorithm for the detection of cow's estrus vocalizations and introduced a prototype system to distinguish the differences between estrus and normal sounds from pattern recognition ...

Formant estimation of speech and singing voice by combining wavelet with LPC and Cepstrum techniques
International Conference on Industrial and Information Systems, 2014Formants are the frequency parts of speech and singing signal those closely describe the human vocal tract geometry. Considering the growing importance of the formants, they are considered the important subject of many work. In this sense, we present two

Formant frequency estimation of high-pitched vowels using weighted linear prediction.
Journal of the Acoustical Society of America, 2013All-pole modeling is a widely used formant estimation method, but its performance is known to deteriorate for high-pitched voices. In order to address this problem, several all-pole modeling methods robust to fundamental frequency have been proposed ...

Formant-Amplitude Measurements
The Journal of the Acoustical Society of America, 1963Five alternative measures of formant amplitude are defined from circuit-theory analysis of speech production. Each of these is studied analytically as a function of increasing voice fundamental frequency, assuming constant shape and size of voice-source pulses. Some of the formant-amplitude measures display periodic fluctuations with maxima each time a

Formants, or vocal-tract resonances, have played a dominant role in the study of both speech production and perception, particularly with vowels. They form the basis of descriptions of speech in phonetics, speech pathology, speaker verification, sociolinguistics, language acquisition, as well as in many other fields.

It is common practice in sociophonetics to measure vowel formants at one (monophthongs) or two (diphthongs) time points. This paper compares this traditional target approach with two dynamic approaches for investigating regional patterns of variation ...

Prosodic features and formant modeling for an ivector-based language recognition system
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2013The prosody of a language is encoded in syllable length, loudness and pitch. These attributes make humans perceive rhythm, stress and intonation in speech.

This paper describes analysis and synthesis methods for a digital formant synthesizer. It is shown that synthetic speech generated using excitation pulses which resemble the true glottal volume-velocity excitation waveform is preferred over speech synthesized using a two-pole glottal filter and impulse excitation.
