Abstract: TrueVoice is a speech enhancement software by Limes Audio AB. It improves the quality of the speech signal by using methods such as acoustic echo cancellation and noise reduction. The real time signal processing of TrueVoice puts some specic requirements on the hardware, which makes some processors more suitable than others to run the code. This thesis looks for good digital signal processor candidates to port the TrueVoice code to. This is done by evaluating memory and number representation aspects in theory and processing power in practice. The conclusion is that Cirrus WM8281 is a good candidate to port TrueVoice to
