FADE - A Simulation Framework for Auditory Discrimination Experiments

FADE is a simulation framework for auditory discrimination experiments. It is aimed to simulate, and hence predict the outcome of different experiments, from basic tone-in-noise detection experiments to the Matrix sentence test in fluctuating noise conditions, using an automatic speech recognition system with a universal set of parameters. The predictions with FADE are reference-free, which means no empirical data is required to perform predictions. The predictions match considerably well with empirical data [1]. The approach is a generalized version of an approach to predict speech intelligibility [2]. It also works with different languages [4], and was successfully used to predict the speech recognition performance of listeners with impaired hearing [3], and the benefit in speech recognition performance due to binaural noise reduction algorithms [5].
