Core Concepts
LeBenchmark 2.0 introduces a standardized framework for assessing and building SSL-equipped French speech technologies, showcasing improved performance and energy considerations.
Abstract
LeBenchmark 2.0 presents an open-source framework for evaluating and developing SSL-equipped French speech technologies. It includes large-scale corpora, pre-trained models, and evaluation tasks. The models outperform previous benchmarks but require more energy for pre-training. LeBenchmark aims to standardize SSL evaluation protocols in the French language.
The content discusses the impact of self-supervised learning (SSL) on various speech processing tasks like ASR, AER, ASV, AST, SLU, SE, SS. It highlights the importance of fair comparisons and standardized evaluation protocols in SSL benchmarking. LeBenchmark 2.0 offers unique perspectives on pre-trained SSL models for speech with a focus on French language-specific tasks.
The article details the datasets used for training SSL models, including diverse speech samples like read, spontaneous, emotional speech from various sources. It also explains the architecture of wav2vec 2.0 models used in pre-training and provides insights into hyperparameters and training environments.
Overall, LeBenchmark 2.0 aims to unify the community around common models, datasets, and evaluation protocols for SSL in the French language.
Stats
Up to 14K hours of heterogeneous speech data used for training.
Models containing from 26 million to one billion learnable parameters shared with the community.
Models trained on 14K hours of French speech outperform multilingual alternatives across benchmarks but require up to four times more energy for pre-training.
