Modelling Speech Signals using Formant Frequencies as an Intermediate Representation
This paper concerns Multiple-level Segmental HiddenMarkov Models (M-SHMMs) in which the relationship between symbolic and acoustic representations of speech is regulated by a formant-based intermediate representation. New TIMIT phone recognition results are presented, confirming that the theoretical upper-bound on performance is achieved provided that either the intermediate representation or t...
متن کاملUsing formant frequencies in speech recognition
Formant frequencies have rarely been used as acoustic features for speech recognition, in spite of their phonetic significance. For some speech sounds one or more of the formants may be so badly defined that it is not useful to attempt a frequency measurement. Also, it is often difficult to decide which formant labels to attach to particular spectral peaks. This paper describes a new method of ...
متن کاملSix-Month-Old Infants Prefer Speech with Raised Formant Frequencies
Voices can be characterized by their fundamental frequency as well as by speech timbre characteristics, such as formant frequencies. While infants’ responses to fundamental frequency characteristics are well established, very little is known about how infants respond to changes in formant frequencies. This study tested whether 6-month-old infants prefer listening to speech with raised formant f...
متن کاملImproved modelling of speech dynamics using non-linear formant trajectories for HMM-based speech synthesis
This paper describes the use of non-linear formant trajectories to model speech dynamics. The performance of the non-linear formant dynamics model is evaluated using HMM-based speech synthesis experiments, in which the 12 dimensional parallel formant synthesiser control parameters and their time derivatives are used as the feature vectors in the HMM. Two types of formant synthesiser control par...
متن کاملVowel onset point detection for noisy speech using spectral energy at formant frequencies
In this paper, we propose a method for robust detection of the vowel onset points (VOPs) from noisy speech. The proposed VOP detection method exploits the spectral energy at formant frequencies of the speech segments present in glottal closure region. In this work, formants are extracted by using group delay function, and glottal closure instants are extracted by using zero frequency filter bas...
