Abstract

This paper describes the implementation of a car handsfree speech enhancement application on a TI TMS320C54x DSP. This fixed-point DSP family is especially suited for wireless applications and it is shown how, by taking full advantage of the DSP architecture and instruction set, advanced wireless speech processing applications can be efficiently implemented on these devices. The performances of the complete speech enhancement application in a car environment are presented, showing that even with a fixed-point arithmetic implementation, high performances close to a floating point implementation can be achieved
