COPECO-Speech: Multimodal Post-Editing with Speech and LLMs for Translation Teaching

Jeevanthi Liyanapathirana, Pierrette Bouillon, Jonathan Mutal, Sabrina Girletti, Lise Volkart


Abstract
In this demo, we present COPECO-Speech, a multimodal post-editing workbench designed for translator training with AI-based translation technologies. It extends an existing pedagogical post-editing platform (COPECO) by integrating speech input and Large Language Model (LLM)-assisted editing. The workbench has different post-editing modalities and helps teachers annotate student tasks using either a shared or personalized annotation scheme. The system logs all interactions—including keystrokes, speech input, editing actions and LLM operations—enabling detailed analysis of post-editing processes.
