The four experiments reported here measure listeners' accuracy and consistency in adjusting a formant frequency of one- or two-formant complex sounds to match the timbre of a target sound. By presenting the target and the adjustable sound on different fundamental frequencies, listeners are prevented from performing the task by comparing the absolute or relative levels of resolved spectral compo...

background and aim: age implantation is one of the effective factors on speech production outcomes in cochlear implanted (ci) children. the purpose of this study is to determine the role of age implantation on formant frequencies and production of three persian vowels including /a/, /u/, /i/ in ci children. methods: sixty nine congenitally deaf children who received ci were divided into three g...

Background: Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success. Previous research has emphasised the importance of vocal tract resonances or formant frequencies of calls as cues to body size in mammals. However, t...

In this master thesis, the formant frequencies of an excellent male Swedish barbershop quartet were examined. The choice of topic was based on several factors that ought to make the tuning of the formant frequencies extremely important in the strive for the characteristic barbershop sound. The quartet was recorded, singing parts of the song 'Paper Moon'. In the recordings, each singer had an in...

This paper presents a new approach for formant tracking using a parameter-free non-linear predictor that maps formant frequencies and bandwidths into the acoustic feature space. The approach relies on decomposing the speech signal into two components: the first component captures the mapping between formants and acoustic observations, while the second component is intended to capture the residu...

This paper examines a method for formant parameter extraction from a labeled single speaker database for use in a formantparameter diphone-concatenation speech synthesis system. This procedure commences with an initial formant analysis of the labelled database, which is then used to obtain formant (F1-F5) probability spaces for each phoneme. These probability spaces guide a more careful speaker...

Neurophysiological changes in the brain associated with major depression disorder can disrupt articulatory precision in speech production. Motivated by this observation, we address the hypothesis that articulatory features, as manifested through formant frequency tracks, can help in automatically classifying depression state. Specifically, we investigate the relative importance of vocal tract f...

This work examines the utility of formant frequencies and their energies in acoustic-to-articulatory inversion. For this purpose, formant frequencies and formant spectral amplitudes are automatically estimated from audio, and are treated as observations for the purpose of estimating electromagnetic articulography (EMA) coil positions. A mixture Gaussian regression model with mel-frequency cepst...

The objective of this study was to assess the difference in voice quality as defined by acoustical analysis using sustained vowel in laryngectomized patients in comparison with normal volunteers. This was designed as a retrospective single center cohort study. An adult tertiary referral unit formed the setting of this study. Fifty patients (40 males) who underwent total laryngectomy and 31 norm...
