This paper discusses the real-time implementation of the wideband sinusoidal (WS) speech coder using the ADSP-21065L EZ-Kit Litetrade evaluation board. To achieve a real-time implementation, optimization strategies were applied to the speech coding algorithms and data collection and speech output blocks were implemented as interrupt service routines (ISRs). The entire WS speech coder was programmed in assembly. This implementation uses 7.35% of the DSP's processing power and 38.94% of the DSP's program and data memory. Listening test results showed that the output speech has acceptable quality and intelligibility, with WS speech coder configurations obtaining MOS greater than 3.0 and DRT scores of higher than 80%.
