Stop consonant classification by dynamic formant trajectory
LPC analysis is one of the most powerful techniques in speech analysis. Spectral zeros during consonant or consonant-vowel transition regions introduce difficulties in estimating LPC parameters. In this paper, we propose to estimate formant frequencies from LPC model by MUSIC (Multiple Signal Classification) and ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques). Form...
متن کاملRelation of vocal tract shape, formant transitions, and stop consonant identification.
PURPOSE The present study was designed to investigate the relation of formant transitions to place-of-articulation for stop consonants. A speech production model was used to generate simulated utterances containing voiced stop consonants, and a perceptual experiment was performed to test their identification by listeners. METHOD Based on a model of the vocal tract shape, a theoretical basis f...
متن کاملEffects of consonant environment on vowel formant patterns.
A significant body of evidence has accumulated indicating that vowel identification is influenced by spectral change patterns. For example, a large-scale study of vowel formant patterns showed substantial improvements in category separability when a pattern classifier was trained on multiple samples of the formant pattern rather than a single sample at steady state [J. Hillenbrand et al., J. Ac...
متن کاملConsonant identification in consonant-vowel-consonant syllables in speech-spectrum noise.
Identification functions of 20 initial and 20 final consonants were characterized in 9600 randomly sampled consonant-vowel-consonant (CVC) tokens presented in speech-spectrum noise. Because of differences in the response criteria for different consonants, signal detection measures were used to quantify identifiability. Consonant-specific baseline signal-to-noise ratios (SNRs) were adjusted to p...
متن کاملVariability in noise-masked consonant identification
Speech communication commonly occurs in the presence of noise. Perceptual errors in the perception of noise-masked speech vary as a function of noise type (e.g., white noise, speech-shaped noise, multi-talker babble), listener characteristics (e.g., listeners with hearing loss, non-native listeners), and target stimulus properties (e.g., native language of the talker, casual vs clear speech). T...
