چکیده

In recent multimedia system, people consider speed, power, and size very important. People want the process to have very high performance and high quality, while consume only small amount of power. Beside the development on better algorithm, special hardware design techniques can also help in increasing performance. This project mainly focuses on the linear predictive coding algorithm on speech. The algorithm is analyzed and a special purpose DSP processor is implemented. The implementation is done using A|RT Designer by Frontier Design, for which we also have a chance to evaluate the effectiveness of the software in implementing the encoder from a high level perspective. The chip can run at 150KHz and

The Quality of Synthesized Sounds

Linear Predictive Coding (LPC) is a basic method used in speech signal processing. The purpose of this work is to implement a real-time LPC vocoder on a TMS320C6455 DSP board to assess the effect of the number of coefficients on sound quality for human voice, and bird and vehicle sounds. The experimental results show that there exists a threshold at which the sound quality is degraded. The thre...

An Efficient Time Domain Speech Compression Algorithm Based on LPC and Sub-Band Coding Techniques

Speech compression is a mature technology with many applications. Over the past decade, huge advances have been made in the area of speech coding for reduced bit-rate transmission. With perceptual audio coding, the signal is coded efficiently using a psychoacoustic model, as in MPEG standards. In this paper, two well known algorithms, LPC (Linear Predictive Coding) and subband coding are combin...
