摘要:

近年来,语音大语言模型(SpeechLLMs)的进展引起了广泛关注。然而,当前方法在遵循语音指令方面表现欠佳。值得注意的是,与直接以文本形式输入相比,模型在处理语音形式输入时智能显著下降。先前工作尝试通过表征对齐和行为对齐等技术来缓解语音与文本表征之间的语义不一致,这些技术需要在后训练阶段精心设计数据对。在本文中,我们提出了一种简单且可扩展的训练方法,称为InSerter,即交错语音-文本表征预训练(Interleaved Speech-Text Representation Pre-training)。InSerter旨在对大规模无监督语音-文本序列进行预训练,其中语音是通过文本转语音转换从大规模文本语料库中随机选取的片段合成而来。因此,模型获得了针对所提供语音片段生成相应文本续写的能力,从而无需进行繁重的数据设计工作。为了系统性地评估语音指令遵循能力,我们引入了SpeechInstructBench,这是首个专门为面向语音的指令遵循任务设计的全面基准。我们提出的InSerter在SpeechInstructBench上取得了SOTA性能,并在多种语音处理任务中展现出优越或具有竞争力的结果。

英文摘要:

Recent advancements in speech large language models (SpeechLLMs) have attracted considerable attention. Nonetheless, current methods exhibit suboptimal performance in adhering to speech instructions. Notably, the intelligence of models significantly diminishes when processing speech-form input as compared to direct text-form input. Prior work has attempted to mitigate this semantic inconsistency between speech and text representations through techniques such as representation and behavior alignment, which involve the meticulous design of data pairs during the post-training phase. In this paper, we introduce a simple and scalable training method called InSerter, which stands for Interleaved Speech-Text Representation Pre-training. InSerter is designed to pre-train large-scale unsupervised speech-text sequences, where the speech is synthesized from randomly selected segments of an extensive text corpus using text-to-speech conversion. Consequently, the model acquires the ability to generate textual continuations corresponding to the provided speech segments, obviating the need for intensive data design endeavors. To systematically evaluate speech instruction-following capabilities, we introduce SpeechInstructBench, the first comprehensive benchmark specifically designed for speech-oriented instruction-following tasks. Our proposed InSerter achieves SOTA performance in SpeechInstructBench and demonstrates superior or competitive results across diverse speech processing tasks.
