Simulstream: Open-Source Toolkit for Evaluation and Demonstration of Streaming Speech-to-Text Translation Systems
Marco Gaido, Sara Papi, Mauro Cettolo +2
Streaming Speech-to-Text Translation (StreamST) requires producing translations concurrently with incoming speech under strict latency constraints, demanding models that balance lo…
FBK's Long-form SpeechLLMs for IWSLT 2026 Instruction Following
Zhihang Xie, Marco Gaido, Sara Papi +2
This paper describes our submission to the IWSLT 2026 Instruction Following shared task. SpeechLLMs are developed for both short-form and long-form speech instruction following und…
Cross-Attention is Half Explanation in Speech-to-Text Models
Sara Papi, Dennis Fucci, Marco Gaido +2
Cross-attention is a core mechanism in encoder-decoder architectures, widespread in many fields, including speech-to-text (S2T) processing. Its scores have been repurposed for vari…
Voice, Bias, and Coreference: An Interpretability Study of Gender in Speech Translation
Lina Conti, Dennis Fucci, Marco Gaido +3
Unlike text, speech conveys information about the speaker, such as gender, through acoustic cues like pitch. This gives rise to modality-specific bias concerns. For example, in spe…
How to Evaluate Speech Translation with Source-Aware Neural MT Metrics
Mauro Cettolo, Marco Gaido, Matteo Negri +2
Automatic evaluation of ST systems is typically performed by comparing translation hypotheses with one or more reference translations. While effective to some extent, this approach…
MCIF: Multimodal Crosslingual Instruction-Following Benchmark from Scientific Talks
Sara Papi, Maike Züfle, Maike Züfle +6
Recent advances in large language models have laid the foundation for multimodal LLMs (MLLMs), which unify text, speech, and vision within a single framework. As these models are r…
