ML-SUPERB evaluates self-supervised learning (SSL) models on the tasks of language identification and automatic speech recognition (ASR). This benchmark treats the models as feature extractors and uses a single shallow downstream model, which can be fine-tuned for a downstream task. However, real-world use cases may require different configurations. This paper presents ML-SUPERB~2.0, which is a new benchmark for evaluating pre-trained SSL and supervised speech models across downstream models, fine-tuning setups, and efficient model adaptation approaches. We find performance improvements over the setup of ML-SUPERB. However, performance depends on the downstream model design. Also, we find large performance differences between languages and datasets, suggesting the need for more targeted approaches to improve multilingual ASR performance.

ML-SUPERB~2.0是一个新的基准系统，用于评估预训练的自监督学习和监督语音模型在下游模型、微调设置和高效模型适应方法方面的性能，它发现了ML-SUPERB设置的性能改进，但性能取决于下游模型设计，并且在语言和数据集之间存在大的性能差异，表明需要更有针对性的方法来改进多语言ASR性能。
