FormantsAcoustic analysesObjectives. This study aimed to describe and correlate the fundamental frequency behavior and the first four formants before and after exposure to usual and routinely prolonged voice use from teachers with over 4 years of experience in teaching.Pellicani, Ariane DamascenoFontes...
METHODS: A total of 28 female teachers were subjected to the Screening Index for Voice Disorder (SIVD) and to recordings of the sustained vowel /a/ before and after exposure to prolonged voice use. Data were obtained about the fundamental frequency and the first four formants before and after...
Identification of gender from speech sounds has been found to rely on speakers' voice fundamental frequency (F0) and formant frequencies. The present study aimed at examining the contribution of F0 and formants to the correct detection o... Goffinet,Jack - 《Proceedings of the National Academy ...
There was always fundamental frequency component in the SABEP to two component complex tones, whether the difference frequency is equal to the fundamental or twice the fundamental. The experimental items include the fundamental frequency (Fo), the rimal duration, the amplitude and the formants. Obj...

My-Voice Analysis is a Python library for the analysis of voice (simultaneous speech, high entropy) without the need of a transcription. It breaks utterances and detects syllable boundaries, fundamental frequency contours, and formants. Its built-in functions recognise and measures ...
(5) distorting means, such as half wave rectifiers, at the input of each low pass filter in each channel to derive the fundamental frequency as from input waves with strongly emphasized formants; (6) an output circuit such a summing circuit connected to each channel at the output of which...
In an isolated syllable, a formant will tend to be segregated perceptually if its fundamental frequency (F0) differs from that of the other formants. This study explored whether similar results are found for sentences, and specifically whether differences in F0 (ΔF0) also influence across-formant...
(regardless of which run of the same-frequency task is entered first; lower two rows of Table1). This result provides evidence that the same-frequency and coherent roving tasks assess different constructs that contribute to speech-in-noise, rather than improving model fit by sampling the same ...
Animplementation of an instantaneous frequency estimator based on thesource--filter model of speech production is described for voicedspeech formants. Based ... P Rao,AD Barman - 《Signal Processing》 被引量: 22发表: 2000年 Speechreading enhancement by voice fundamental frequency: the effects of ...
