An Extraction Algorithm for Voice Signal Feature Based on Multifractal Analysis
This paper utilizes the multiple fractal theories to define the box dimension and the multiple fractal dimensions, and realizes the feature of voice signal. Then it designs an extraction algorithm for voice signal feature. The result shows, the multifractal method is better than sole fractal method and it may be the characteristic parameter of the voice recognition.
