Optimization of Speech Recognition using LPC Technic
Vipulsangram K. Kadam · IOSR Journal of Engineering · 2012
Here you implement a speech compression technique known as Linear Prediction Coding(LPC) using DSP System Toolbox from Mat lab functionality available at the MATLAB command line.In this system we uses the Levinson-Durbin and Time-Varying Lattice Filter blocks for low-bandwidth transmission of speech using linear predictive coding.At present, VBEC automatic determination only considers the optimum topology for training data, and does not consider the effects of the decoding condition on the optimality (e.g., mixture and state pruning process and the search parameter dependence in decoding) for the optimum model topology.We need further study on the superiority from a practical point of view.In future work, I would like to extend the model determination taking the decoding process into consideration, for example, by reflecting the effect of the decoding strategy of the mixture or state pruning process in the objective function of our optimized tool for speech recognition.We have further focus on how to optimize the optimum area as shown in following fig1.considering the decoding process.This can be achive by LPC Technic as shown below.[10
