Abstract: Automatic disorder recognition in speech can be very helpful for the therapist while monitoring therapy progress of the patients with disordered speech. In this article we focus on prolongations. We analyze the signal using Continuous Wavelet Transform with 22 bark scales, we divide the result into vectors (using windowing) and then we pass such vectors into Kohonen network. We have increased the recognition ratio from 54% to 81% by adding a modification into the network learning process as well as into CWT computation algorithm. All the analysis was performed and the results were obtained using the authors’ program – “WaveBlaster”. It is very important that the recognition ratio above 80% was obtained by a fully automatic algorithm (without a teacher). The presented problem is part of our research aimed at creating an automatic prolongation recognition system.
