A Speech Recognition Method Based on LPCC and Fractal Dimension for Mobile Robot

摘要：

In this paper, we propose a speech recognition approach with mixed parameter, which combines the traditional Linear Predictive Cepstral Coefficients (LPCC) and fractal feature as the feature parameter. The LPCC method is linear procedure based on the assumption that speaker features have properties caused by the vocal tract resonances. Fractal dimension is used to quantitatively describe the chaos nonlinearity in speech air flow. Experimental results demonstrate this method is promising in improving speech recognition performance.
