arXiv:2606.17255v1 Announce Type: new Abstract: This work describes the participation of the MLLP-VRAIN research group in the shared task of the IWSLT 2026 Simultaneous Speech Translation track. Our submission utilizes the recently released Parakeet and Qwen 3.5 models to create a robust, cascaded solution for long-form SimulST through the use of adaptive "black-box" policies. We explore relaxations of these policies to achieve better quality-latency trade-offs. Compared to last year, we participate on all language directions. In addition to this, for the En$\rightarrow${De, It, Zh} directions
The IWSLT 2026 challenge provides a platform for advancements in simultaneous speech translation, reflecting ongoing R&D in real-time AI communication. The use of specific, recently released models points to current trends in large language model application.
Advancements in simultaneous speech translation are critical for overcoming language barriers in multinational operations, humanitarian efforts, and global commerce, reducing friction in real-time communication.
The ability to achieve better quality-latency trade-offs in long-form simultaneous speech translation through adaptive policies indicates a step towards more practical and deployable solutions.
