One of the most common applications of Fairseq among speech processing enthusiasts is wav2vec (and all the variants), a framework that aims to extract new types of input vectors for acoustic models from raw audio, using pre-training and self-supervised learning. The resource should ideally demonstrate something new instead of duplicating an existing resource.
