摘要:

近期的端到端语音语言模型(SLMs)通过整合预训练语音模型,拓展了大语言模型(LLMs)的能力。然而,这类SLM通常需要进行大量语音指令微调,以弥合语音与文本模态之间的差距。这需要投入大量标注工作,还存在导致原有语言能力发生灾难性遗忘的风险。本研究提出了一种简单却有效的自动化流程,用于生成语音-文本配对数据,该流程可在保留基于文本的LLM固有语言能力的同时,将语音副语言理解能力精准注入SLM中。我们的模型在无需语音指令微调数据的情况下,展现出处理语音相关任务的通用能力,在Dynamic-SUPERB和AIR-Bench-Chat基准上取得了优异性能。此外,该模型具备遵循源自LLM的复杂指令的能力,例如特定输出格式要求与思维链推理。我们的方法不仅提升了SLM的通用性与有效性,还降低了对大规模标注数据集的依赖,为构建更高效、性能更强的语音理解系统铺平了道路。

英文摘要:

Recent end-to-end speech language models (SLMs) have expanded upon the capabilities of large language models (LLMs) by incorporating pre-trained speech models. However, these SLMs often undergo extensive speech instruction-tuning to bridge the gap between speech and text modalities. This requires significant annotation efforts and risks catastrophic forgetting of the original language capabilities. In this work, we present a simple yet effective automatic process for creating speech-text pair data that carefully injects speech paralinguistic understanding abilities into SLMs while preserving the inherent language capabilities of the text-based LLM. Our model demonstrates general capabilities for speech-related tasks without the need for speech instruction-tuning data, achieving impressive performance on Dynamic-SUPERB and AIR-Bench-Chat benchmarks. Furthermore, our model exhibits the ability to follow complex instructions derived from LLMs, such as specific output formatting and chain-of-thought reasoning. Our approach not only enhances the versatility and effectiveness of SLMs but also reduces reliance on extensive annotated datasets, paving the way for more efficient and capable speech understanding systems.
