Abstract

Razvojem tehnologije, digitalni sustavi su svoju popularnost doživjeli osamdesetih godina te danas imamo razne uređaje za obradbu zvuka koji se mogu primijeniti za obradbu i analizu govora. Uređaj za obradbu govora opisan u ovom radu služi za rehabilitaciju slušnih i govornih poremećaja te se bazira na verbotonalnoj metodi, točnije optimalama. Za obradbu govora koriste se tercno-oktavne filtarske banke koje precizno simuliraju ljudsku percepciju zvuka. Razvijen je sustav koji, preko grafičkog sučelja, omogućuje odabir optimala koji u stvarnom vremenu nudi rješenje rehabilitacije ovakve vrste poremećaja. Navedena su moguća ograničenja u radu, ali isto tako i poboljšanja za daljnji razvoj ovakvog sustava.

Abstract (english)

With development of technology, digital systems had gained increasing popularity in the eighties and today we have a variety of sound processing devices that can be used for speech processing and analysis. The speech processing device described in this paper has their use for speech and hearing disorder rehabilitation and is based on the verbotonal method, more precisely, the optimals. Third-octave filter banks are used for speech processing that accurately simulates human perception of sound. A system has been developed allowing the selection of the optimal, via graphical interface, which provides real-time solution for the rehabilitation of this type of disorder. Possible limitations, but also improvements are listed in the thesis for ongoing development of such system.
