摘要:

学习的语音表示可以大大提高有限标记数据的任务性能。然而,由于它们的大小和复杂性,学习表示在移动环境中的实用性有限,其中运行时性能可能是一个重要的瓶颈。在这项工作中,我们提出了一类轻量级的非语义语音嵌入模型,有效地运行在移动设备上最近提出的TRILL语音嵌入的基础上。我们结合新的架构修改与现有的加速技术,以创建嵌入模型,是足够快的实时运行在一个移动终端上,并表现出最小的性能下降的基准上的非语义语音任务。其中一个模型(FRILL)在Pixel 1智能手机上的速度快32倍,尺寸是TRILL的40%,准确度平均仅降低2%。据我们所知,FRILL是专为移动设备设计的最高质量的非语义嵌入。此外,我们证明,这些表示是有用的移动健康任务,如非语音人类声音检测和蒙面语音检测。我们的模型和代码是公开的。

英文摘要:

Learned speech representations can drastically improve performance on tasks with limited labeled data. However, due to their size and complexity, learned representations have limited utility in mobile settings where run-time performance can be a significant bottleneck. In this work, we propose a class of lightweight non-semantic speech embedding models that run efficiently on mobile devices based on the recently proposed TRILL speech embedding. We combine novel architectural modifications with existing speed-up techniques to create embedding models that are fast enough to run in real-time on a mobile device and exhibit minimal performance degradation on a benchmark of non-semantic speech tasks. One such model (FRILL) is 32x faster on a Pixel 1 smartphone and 40% the size of TRILL, with an average decrease in accuracy of only 2%. To our knowledge, FRILL is the highest-quality non-semantic embedding designed for use on mobile devices. Furthermore, we demonstrate that these representations are useful for mobile health tasks such as non-speech human sounds detection and face-masked speech detection. Our models and code are publicly available.
