Sažetak
This paper presents one step of speech recognition problem related to local communication system implementation. Practical considerations are limited to the set of Croatian words chosen for a speaker dependent experiment. Speech signal used is under ISDN B-channelk standard. A FFT algorithm is applied for signal preprocessing, together with zero crossing rate and short term energy, to give a relevant parameters of the speech. Artificial neural network then is used to learn the vowels by back-propagation algorithm.
