Unlocking Speech-Text Compositional Powers: Instruction-Following Speech Language Models without Instruction Tuning

arXiv:2607.02214v1 Announce Type: new Abstract: Instruction tuning for speech language models (SLMs) is substantially more challenging than for text-based large language models (LLMs), as it requires learning a new modality and a wide range of speech-specific instructions in addition to those supported by text LLMs. Existing SLM training approaches largely replicate the text LLM training paradigm by synthesizing large-scale speech pre-training and instruction-tuning datasets. However, this strategy is difficult to scale, since speech sequences are significantly longer than text sequences. In t

Why this matters
Why now

The paper unveils a novel approach to training instruction-following Speech Language Models (SLMs) without the need for extensive instruction tuning, addressing current scalability challenges.

Why it’s important

This research provides a more efficient pathway for developing advanced SLMs, potentially accelerating the deployment of sophisticated voice-controlled AI agents and ubiquitous AI assistants.

What changes

Current speech language model training reliance on large-scale, difficult-to-scale instruction-tuning datasets is challenged by a new methodology, potentially simplifying future SLM development.
