C ross - modal Clustering in the Acoustic - Articulatory Space

This paper explores cross/modal clustering in the acoustic/articulatory space. A method to improve clustering using information from more than one modality is presented. Formants and the Electromagnetic Articulography meas/ urements are used to study corresponding clus/ ters formed in the two modalities. A measure for estimating the uncertainty in correspon/ dences between one cluster in the acoustic space and several clusters in the articulatory space is suggested.
