2M-BELEBELE: Highly Multilingual Speech and American Sign Language Comprehension Dataset Download PDF

ACL 2025finding

We introduce the first highly multilingual speech and American Sign Language (ASL) comprehension dataset by extending BELEBELE. Our dataset covers 91 spoken languages at the intersection of BELEBELE and FLEURS, and one sign language (ASL). As a by-product we also extend the Automatic Speech Recognit…

Linguini: A benchmark for language-agnostic linguistic reasoning

NeurIPS 2025poster

We propose a new benchmark to measure a language model's linguistic reasoning skills without relying on pre-existing language-specific knowledge. The test covers 894 questions grouped in 160 problems across 75 (mostly) extremely low-resource languages, extracted from the International Linguistic Oly…

Mixture of Languages: Improved Multilingual Encoders Through Language Grouping

EMNLP 2025

We propose Mixture of Languages (MoL), a new strategy to pretrain largely multilingual encoders. Recent work in this field has relied on training transformer encoders on a large amount of multilingual data, with all parameters shared across all languages, without studying how to optimally balance la

SpeechAlign: A Framework for Speech Translation Alignment Evaluation

COLING 2024main

Speech-to-Speech and Speech-to-Text translation are currently dynamic areas of research. In our commitment to advance these fields, we present SpeechAlign, a framework designed to evaluate the underexplored field of source-target alignment in speech models. The SpeechAlign framework has two core com…

Unveiling the Role of Pretraining in Direct Speech Translation

EMNLP 2024main

Direct speech-to-text translation systems encounter an important drawback in data scarcity. A common solution consists on pretraining the encoder on automatic speech recognition, hence losing efficiency in the training process. In this study, we compare the training dynamics of a system using a pret…

Towards Opening the Black Box of Neural Machine Translation: Source and Target Interpretations of the Transformer

EMNLP 2022main

In Neural Machine Translation (NMT), each token prediction is conditioned on the source sentence and the target prefix (what has been previously translated at a decoding step). However, previous work on interpretability in NMT has mainly focused solely on source sentence tokens’ attributions. Theref…
