His innovative approach has led to the development of a unique patent that enhances the understanding of speech signal quality.

Latest Patents

Morfitt holds a patent titled "Mapping objective voice quality metrics to a MOS domain for field measurements." This patent describes a processing unit and method capable of estimating the quality of a speech signal transmitted through a wireless network. The processing unit utilizes a logistic function to map a score output from an objective voice quality method, specifically the PESQ algorithm, into a mean opinion score (MOS). The logistic function is defined as: y=1+4/(1+exp(−1.7244*x+5.0187)), where x represents the score from the PESQ algorithm, ranging from -0.5 to 4.5, and y is the mapped MOS score, which ranges from 1 to 5. A score of y=5 indicates excellent quality, while y=1 signifies poor quality.
