用于低资源语音到意图应用的预训练

Pre-training for low resource speech-to-intent applications

KU Leuven(鲁汶大学)

Pu Wang, Hugo Van hamme

摘要:

由于不同用户的语法和词汇偏好不同,设计将用户的口头命令映射到代理的期望任务动作的语音到意图(S2 I)代理可能具有挑战性。作为一种补救措施,我们在本文中讨论了一个用户教S2 I系统。用户自教系统从用户的语音输入中从头开始学习,并进行动作演示,确保它完全匹配用户制定意图的方式和他们的发音习惯。主要问题是由于用户的努力而导致的训练数据稀缺。在这种情况下,现有的最先进的方法是基于非负矩阵分解(NMF)和胶囊网络。在本文中,我们将端到端ASR系统的编码器与先前的基于NMF/胶囊网络的用户自教解码器相结合,并研究预训练方法是否可以减少NMF和胶囊网络的训练数据要求。实验结果表明,预训练的ASR-NMF框架显着优于其他模型,同时,我们讨论了不同类型的命令和控制(C&C)应用程序的预训练的局限性。

英文摘要:

Designing a speech-to-intent (S2I) agent which maps the users' spoken commands to the agents' desired task actions can be challenging due to the diverse grammatical and lexical preference of different users. As a remedy, we discuss a user-taught S2I system in this paper. The user-taught system learns from scratch from the users' spoken input with action demonstration, which ensure it is fully matched to the users' way of formulating intents and their articulation habits. The main issue is the scarce training data due to the user effort involved. Existing state-of-art approaches in this setting are based on non-negative matrix factorization (NMF) and capsule networks. In this paper we combine the encoder of an end-to-end ASR system with the prior NMF/capsule network-based user-taught decoder, and investigate whether pre-training methodology can reduce training data requirements for the NMF and capsule network. Experimental results show the pre-trained ASR-NMF framework significantly outperforms other models, and also, we discuss limitations of pre-training with different types of command-and-control(C&C) applications.
