Data-Centric Lessons To Improve Speech-Language Pretraining

Summary

The article presents a comprehensive study on improving Speech-Language Models (SpeechLMs) through data-centric approaches. It identifies critical research questions regarding the processing of raw audio data, the construction of synthetic datasets, and the interleaving of text and audio segments for effective training. By conducting controlled ablations, the authors demonstrate that their 3.8B-parameter model, SpeLangy, significantly outperforms larger models, emphasizing the importance of data curation in enhancing model performance. The findings aim to guide future research in the domain of SpeechLMs by highlighting effective data strategies.
