The idea of using articulatory representations for automatic speech recognition (ASR) continues to attract much attention in the speech community. Representations which are grouped under the label ‘‘articulatory’’ include articulatory parameters derived by means of acoustic-articulatory transformations (inverse filtering), direct physical measurements or classification scores for pseudo-articul...

This paper presents a study of the articulatory properties of French vowels using an acoustic-to-articulatory inversion method. The advantage of such an approach is that all the possible articulatory configurations can be studied independently of any articulatory preferences linked with a given speaker. Furthermore, it bypasses the issue of acquiring a vast amount of articulatory data by medica...

This paper aims to examine the interaction of intonation and lexical tone within the framework of Articulatory Phonology, by investigating the timing relationship between oral articulatory gestures and tone-related/intonation-related F0 dynamics. Specifically, we compared the consonant-vowel-F0 (C-V-T) coordinative patterns at phrase-final position and at phrase-medial position. We found that t...

Learners often struggle with L2 sounds, yet little is known about the role of prior pronunciation knowledge and explicit articulatory training in language acquisition. This study asks if existing pronunciation knowledge can bootstrap word learning, and whether short-term audiovisual articulatory training for tongue position with and without a production component has an effect on lexical retent...

Automatic speech recognition (ASR) is a computerized speech-to-text process, in which speech is usually recorded with acoustical microphones by capturing air pressure changes. This kind of air-transmitted speech signal is prone to two kinds of problems related to noise robustness and applicability. The former means the mixing of speech signal and ambient noise usually deteriorates ASR performan...

PURPOSE This study aimed to compare sound production errors arising due to phonological processing impairment with errors arising due to motor speech impairment. METHOD Two speakers with similar clinical profiles who produced similar consonant cluster simplification errors were examined using a repetition task. We compared both overall accuracy and acoustic details of hundreds of productions ...

PURPOSE To investigate the articulatory awareness of children with normal phonological development according to the variables gender, age and schooling, as well as to analyze their performances in speech perception and production tasks. METHODS Participants were 90 Preschool and Elementary School students, with ages between 5 and 7 years, who were evaluated using the Articulatory Awareness In...

A factor analysis of vocal-tract outlines derived automatically from real-time magnetic resonance image (rtMRI) sequences has been performed. The analysis results in a compact representation of vocaltract shapes, where every utterance is represented by a small set of trajectories corresponding to weights in linear combinations of linguistically interpretable vocal-tract deformations. Vocal-trac...
