Presented at ICASSP 2016, we explore ways to improve speech privacy in multizone soundfield reproductions using intelligibility metrics, all while maintaining high speech quality.
There are a few robust algorithms available to objectively measure the intelligibility of speech. They compare what is heard by a listener to the information that was transmitted by the talker, however, only one of these available algorithms works in reverberant rooms and at the time I was looking for an implementation for MATLAB, I couldn’t find any, zilch. So, I decided to code it from scratch myself and will show you how to do it step by step. Continue reading The Speech Transmission Index (STI) for MATLAB
