Does Translation-Enhanced Speech Encoder Pre-training Affect Speech LLMs?

Tomoya Mizumoto, Yusuke Fujita

Connecting a pre-trained speech encoder to a Large Language Model (LLM) is the standard architecture for building Speech LLMs. However, a structural misalignment exists between the…

Evaluating Japanese Dialect Robustness Across Speech and Text-based Large Language Models

Tomoya Mizumoto, Yusuke Fujita, Hao Shi +3

Dialogue systems based on large language models (LLMs) have advanced significantly in recent years. However, dialectal variation remains a major challenge, particularly for systems…

Serialized Output Prompting for Large Language Model-based Multi-Talker Speech Recognition

Hao Shi, Yusuke Fujita, Tomoya Mizumoto +3

Prompts are crucial for task definition and for improving the performance of large language models (LLM)-based systems. However, existing LLM-based multi-talker (MT) automatic spee…

AC/DC: LLM-based Audio Comprehension via Dialogue Continuation

Yusuke Fujita, Tomoya Mizumoto, Atsushi Kojima +2

We propose an instruction-following audio comprehension model that leverages the dialogue continuation ability of large language models (LLMs). Instead of directly generating targe…

OWSM-Biasing: Contextualizing Open Whisper-Style Speech Models for Automatic Speech Recognition with Dynamic Vocabulary

Yui Sudo, Yusuke Fujita, Atsushi Kojima +2

Speech foundation models (SFMs), such as Open Whisper-Style Speech Models (OWSM), are trained on massive datasets to achieve accurate automatic speech recognition. However, even SF…
