A Robust Method for Blindly Estimating Speech Transmission Index using Convolutional Neural Network with Temporal Amplitude Envelope

We have developed a robust scheme for blindly estimating the speech transmission index (STI) based on a convolutional neural network (CNN) with temporal amplitude envelope as features. When assessing the quality of acoustics in a room where there are people present, STI needs to be estimated without measuring the room impulse response (RIR) or using a modulation transfer function (MTF). This estimation can be problematic because a blind method...
