1. A method comprising: receiving, by a computing device, audiovisual input comprising audio input and video input associated with a subject; extracting, by the computing device, visual features from the video input; applying, by the computing device, a scattering operation to the extracted visual features to generate a vector of scattering coefficients in a first dimensional space; providing the vector of scattering coefficients as input to a first neural network for visual processing; and generating, by the computing device and using the first neural network, a first prediction regarding a speech status of the subject based on the vector of scattering coefficients.
