Signal Processing. This project is focus on the topic of voice conversion, which involves producing the speech compression. The aim of speech compression is to produce a compact representation of speech sounds such that when reconstructed it is perceived to be close to the original. In addition to the implementation of a set of methods, as LPC (Linear Prediction Coding) techniques, encoding good quality speech at a low bit rate and provides extremely accurate estimates of speech parameters. Linear predictive coding (LPC) is defined as a digital method for encoding an analog signal in which a particular value is predicted by a linear function of the past values of the signal. It was first proposed and approved as a method for encoding human speech. The main steps of the complete project include: a method for compressing voice transformation, create a programming in Matlab software and finally translating it into Digital Signal Processing board. |
