摘要:

在过去十年的自动语音识别(ASR)研究中,与没有深度学习的建模相比,深度学习的引入使单词错误率大幅降低了50%以上。在这种转变之后,引入了许多全神经ASR架构。这些所谓的端到端(E2E)模型提供高度集成的、完全神经的ASR模型,这些模型强烈依赖于一般的机器学习知识,从数据中更一致地学习,同时较少依赖于ASR领域特定的经验。深度学习的成功和热情采用伴随着更通用的模型架构,导致E2E模型现在成为突出的ASR方法。本调查的目标是提供一个分类的E2E ASR模型和相应的改进,并讨论其属性和经典的隐马尔可夫模型(HMM)的ASR架构的关系。本工作涵盖了E2E ASR的所有相关方面:建模、培训、解码和外部语言模型集成,并讨论了性能和部署机会,以及对未来潜在发展的展望。

英文摘要:

In the last decade of automatic speech recognition (ASR) research, the introduction of deep learning brought considerable reductions in word error rate of more than 50% relative, compared to modeling without deep learning. In the wake of this transition, a number of all-neural ASR architectures were introduced. These so-called end-to-end (E2E) models provide highly integrated, completely neural ASR models, which rely strongly on general machine learning knowledge, learn more consistently from data, while depending less on ASR domain-specific experience. The success and enthusiastic adoption of deep learning accompanied by more generic model architectures lead to E2E models now becoming the prominent ASR approach. The goal of this survey is to provide a taxonomy of E2E ASR models and corresponding improvements, and to discuss their properties and their relation to the classical hidden Markov model (HMM) based ASR architecture. All relevant aspects of E2E ASR are covered in this work: modeling, training, decoding, and external language model integration, accompanied by discussions of performance and deployment opportunities, as well as an outlook into potential future developments.
