Samsung Introduces Weight-Decomposed Low-Rank Adaptation for Enhanced Speaker Personalization in ASR

[城市,日期] – 在全球领先的语音识别、语音合成、说话人识别和语音语言处理技术会议Interspeech 2024系列活动中,三星展示了其最新的研究成果——使用权重分解低秩自适应技术进行说话人个性化自动语音识别(ASR)。

背景介绍

自动语音识别技术在语音助手系统中的应用越来越广泛,而个性化语音识别技术更是被视为该领域的“圣杯”。在处理有限说话人数据的情况下,如何优化模型成为关键。三星的研究团队提出了使用低秩自适应(LoRA)和权重分解低秩自适应(DoRA)技术,以提升说话人个性化ASR系统的性能。

研究方法

三星的研究团队对现有的级联卷积神经网络(Conformer)转码器模型进行了优化,通过添加少量的说话人特定权重并相应地进行微调,实现了说话人个性化。实验结果表明,在有限数据情况下,该方法的平均相对词错误率降低了20%,证明了其在实际应用中的有效性。

研究成果

该研究采用了两种低秩自适应变体——LoRA和DoRA,对ASR系统中的说话人个性化进行了探索。其中,LoRA方法通过向权重矩阵中添加一小部分参数来实现,而DoRA则通过权重分解技术优化权重矩阵。

实验结果

实验结果显示,使用LoRA和DoRA技术进行说话人个性化后,在有限数据情况下,ASR系统的性能得到了显著提升。这表明该技术有望为ASR系统的实际应用提供更精确的个性化体验。

总结

三星的研究成果为ASR技术的进一步发展提供了新的思路和方法。随着人工智能技术的不断进步,未来语音识别技术将在更多场景中得到应用,为用户带来更加便捷和个性化的体验。
