Researchers have investigated the redundancy within decoder layers of Speech Large Language Models (SpeechLLMs), which typically comprise over 90% of the model's parameters. Their study across various model sizes revealed that a significant portion of these decoder layers can be pruned without substantially impacting Automatic Speech Recognition (ASR) performance. Findings indicate that even 7-8B parameter models can retain good ASR capabilities with only 60% of their decoder layers intact, a trend observed across different scales and tasks, including speech translation.
