Due to the new techniques of analysis and synthesis of speech signals, the musical signal processing has gained particular weight, L-Lysine and therefore, the classical sound analysis techniques are used in processing music signals.In this paper, a general three-level algorithm for discriminating three general types of signals: speech, music, and mixture of both signals is proposed.The proposed classifier is Island Hood based on the well-known zero-crossing rate (ZCR) [1] and short-time energy (STE) [2,3] algorithms, with the positive derivative and voting procedures.
Some theoretical analysis and simulation has been applied to a library of different types of musical and speech signals to show the performance of the proposed algorithm.
