Abstract :
The stack linguistic decoder described in references (1,3,6) has been modified to operate directly on continuous parameter vectors produced by an acoustic processor, thereby bypassing entirely labeling and segmentation of the speech signal. A recognition experiment has been carried out on a natural speech corpus using five-dimensional vectors composed of the four Dutch vowel factors of Klein, Plomp, and Pols, plus an indicator of short-term changes in overall power. The results are compared to those from an earlier experiment in which a centisecond labeling acoustic processor was used.
