Omnilingual SONAR: Cross-Lingual and Cross-Modal Sentence Embeddings Bridging Massively Multilingual Text and Speech

Omnilingual SONAR Team, João Maria Janeiro, Pere-Lluís Huguet Cabot +17

Cross-lingual sentence encoders typically cover only a few hundred languages and often trade downstream quality for stronger alignment, limiting their adoption. We introduce OmniSO…

Omnilingual MT: Machine Translation for 1,600 Languages

Omnilingual MT Team, Belen Alastruey, Niyati Bafna +29

High-quality machine translation (MT) can scale to hundreds of languages, setting a high bar for multilingual systems. However, compared to the world's 7,000 languages, current sys…

Interference Matrix: Quantifying Cross-Lingual Interference in Transformer Encoders

Belen Alastruey, João Maria Janeiro, Alexandre Allauzen +3

In this paper, we present a comprehensive study of language interference in encoder-only Transformer models across 83 languages. We construct an interference matrix by training and…

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

Marta R. Costa-jussà, Bokai Yu, Pierre Andrews +7

We introduce the first highly multilingual speech and American Sign Language (ASL) comprehension dataset by extending BELEBELE. Our dataset covers 74 spoken languages at the inters…

Unveiling the Role of Pretraining in Direct Speech Translation

Belen Alastruey, Gerard I. Gállego, Marta R. Costa-jussà

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, h…

Linguini: A benchmark for language-agnostic linguistic reasoning

Eduardo Sánchez, Belen Alastruey, Christophe Ropers +3

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 grou…

Towards Real-World Streaming Speech Translation for Code-Switched Speech

Belen Alastruey, Matthias Sperber, Christian Gollan +3

Code-switching (CS), i.e. mixing different languages in a single sentence, is a common phenomenon in communication and can be challenging in many Natural Language Processing (NLP)…

SpeechAlign: a Framework for Speech Translation Alignment Evaluation

Belen Alastruey, Aleix Sant, Gerard I. Gállego +2

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…

The Gender-GAP Pipeline: A Gender-Aware Polyglot Pipeline for Gender Characterisation in 55 Languages

Benjamin Muller, Belen Alastruey, Prangthip Hansanti +7

Gender biases in language generation systems are challenging to mitigate. One possible source for these biases is gender representation disparities in the training and evaluation d…

Multi-View Frequency-Attention Alternative to CNN Frontends for Automatic Speech Recognition

Belen Alastruey, Lukas Drude, Jahn Heymann +1

Convolutional frontends are a typical choice for Transformer-based automatic speech recognition to preprocess the spectrogram, reduce its sequence length, and combine local informa…

Multiformer: A Head-Configurable Transformer-Based Model for Direct Speech Translation

Gerard Sant, Gerard I. Gállego, Belen Alastruey +1

Transformer-based models have been achieving state-of-the-art results in several fields of Natural Language Processing. However, its direct application to speech tasks is not trivi…

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

Javier Ferrando, Gerard I. Gállego, Belen Alastruey +2

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). How…

On the Locality of Attention in Direct Speech Translation

Belen Alastruey, Javier Ferrando, Gerard I. Gállego +1

Transformers have achieved state-of-the-art results across multiple NLP tasks. However, the self-attention mechanism complexity scales quadratically with the sequence length, creat…

Efficient Transformer for Direct Speech Translation

Belen Alastruey, Gerard I. Gállego, Marta R. Costa-jussà

The advent of Transformer-based models has surpassed the barriers of text. When working with speech, we must face a problem: the sequence length of an audio input is not suitable f…
