• Abstract summary: Simultaneous Speech-to-text Translation (SimulST) systems translate source speech in tandem with the speaker using partial input. Recent works have tried to leverage the text translation task to improve the performance of Speech Translation (ST) in the offline domain. Motivated by these improvements, we propose to add Decision Attentive Regularization (DAR) to Monotonic Multihead Attention (MMA) based SimulST systems.

• Abstract: Simultaneous Speech-to-text Translation (SimulST) systems translate source speech in tandem with the speaker using partial input. Recent works have tried to leverage the text translation task to improve the performance of Speech Translation (ST) in the offline domain. Motivated by these improvements, we propose to add Decision Attentive Regularization (DAR) to Monotonic Multihead Attention (MMA) based SimulST systems. DAR improves the read/write decisions for speech using the Simultaneous text Translation (SimulMT) task. We also extend several techniques from the offline domain to the SimulST task. Our proposed system achieves significant performance improvements for the MuST-C English-German (EnDe) SimulST task, where we provide an average BLUE score improvement of around 4.57 points or 34.17% across different latencies. Further, the latency-quality tradeoffs establish that the proposed model achieves better results compared to the baseline.

  Simultaneous speech translation (SimulST) produces translations incrementally while processing partial speech input. Existing LLM-based SimulST approaches incur significant computational overhead due to repeated encoding of bidirectional speech encoder. We introduce Efficient and Adaptive Simultaneous Speech Translation (EASiST) with fully unidirectional architecture.

  This paper investigates how large language models (LLMs) can improve the performance of speech translation by introducing a joint refinement process. Through the joint refinement of speech translation (ST) and automatic speech recognition (ASR) transcription via LLMs, the performance of the ST model is significantly improved. Experimental results on the MuST-C and CoVoST 2 datasets, which include seven translation tasks, demonstrate the effectiveness of the proposed approach.

  We investigate the consistency between different tasks, considering different times and modules. We find that the textual encoder primarily facilitates cross-modal conversion, but the presence of noise in speech impedes the consistency between text and speech representations. We propose an improved multi-task learning (IMTL) approach for the ST task, which bridges the modal gap by mitigating the difference in length and representation.
