Formant estimation for speech recognition
This paper presents a new method for estimating formant frequencies. The formant model is based on a digital resonator. Each resonator represents a segment of the short-time power spectrum. The complete spectrum is modeled by a set of digital resonators connected in parallel. An algorithm based on dynamic programming produces both the model parameters and the segment boundaries that optimally m...
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 کاملIndirect estimation of formant frequencies through mean spectral variance with application to automatic gender recognition
A novel approach for estimation of speaker specific vocal tract properties is presented in this paper. Instead of using the well-known long-term average spectrum (LTAS) of speech, it is shown that the variance of the magnitude of the spectrum in each band is also suitable for estimation of formant frequencies. This representation, called mean spectral variance (MSV), is applied to an automatic ...
متن کاملEvaluation of formant-like features for automatic speech recognition
This study investigates possibilities to find a low-dimensional, formant-related physical representation of speech signals, which is suitable for automatic speech recognition. This aim is motivated by the fact that formants are known to be discriminant features for speech recognition. Combinations of automatically extracted formant-like features and state-of-the-art, noise-robust features have ...
متن کاملMethods for estimation of glottal pulses waveforms exciting voiced speech
Nowadays, the most popular techniques of the speech processing are the recognition of all kinds (the speech, the speaker and the state of speaker recog.) and the text-to-speech synthesis. In both these domains, there are possibilities to use the glottal pulses waveforms. In the recognition techniques we can use them for the vocal cords description and then use it for the classification of speak...
