• Abstract: Speech representation learning plays a vital role in speech processing. Among them, self-supervised learning (SSL) has become an important research direction. It has been shown that an SSL pretraining model can achieve excellent performance in various downstream tasks of speech processing. On the other hand, supervised multi-task learning (MTL) is another representation learning paradigm, which has been proven effective in computer vision (CV) and natural language processing (NLP). However, there is no systematic research on the general representation learning model trained by supervised MTL in speech processing. In this paper, we show that MTL finetuning can further improve SSL pretraining. We analyze the generalizability of supervised MTL finetuning to examine if the speech representation learned by MTL finetuning can generalize to unseen new tasks.

  Large language models (LLMs) exploit in-context learning (ICL) to solve tasks with only a few demonstrations. We characterize two ways through which ICL leverages demonstrations. We show that models can achieve non-trivial performance with only TR, and TR does not further improve with larger models or more demonstrations.
