Does Your Voice Assistant Remember? Analyzing Conversational Context Recall and Utilization in Voice Interaction Models

Year: 2025

Type: conference-paper

Abstract: Recent advancements in multi-turn voice interaction models have improved user-model communication.However, while closed-source models effectively retain and recall past utterances, whether open-source models share this ability remains unexplored.To fill this gap, we systematically evaluate how well open-source interaction models utilize past utterances using ContextDialog, a benchmark we proposed for this purpose.Our findings show that speechbased models have more difficulty than textbased ones, especially when recalling information conveyed in speech, and even with retrieval-augmented generation, models still struggle with questions about past utterances.These insights highlight key limitations in opensource models and suggest ways to improve memory retention and retrieval robustness.
