摘要:

端到端模型在自动语音识别(ASR)领域得到了广泛的关注。它们的优点之一是构造简单,直接用神经网络将语音帧序列识别为文本标签序列。根据识别过程中驱动端的不同,端到端的ASR模型可以分为标签同步和帧同步两类,每一类模型都有其独特的行为和特征。在这项工作中,我们做了详细的比较,一个代表性的标签同步模型(Transformer)和软帧同步模型(连续集成和火灾(CIF)为基础的模型)。在三个公共数据集和一个12000小时训练数据的大规模数据集上的实验结果表明,两类模型各有优势,这与它们的同步模式是一致的。

英文摘要:

End-to-end models are gaining wider attention in the field of automatic speech recognition (ASR). One of their advantages is the simplicity of building that directly recognizes the speech frame sequence into the text label sequence by neural networks. According to the driving end in the recognition process, end-to-end ASR models could be categorized into two types: label-synchronous and frame-synchronous, each of which has unique model behaviour and characteristic. In this work, we make a detailed comparison on a representative label-synchronous model (transformer) and a soft frame-synchronous model (continuous integrate-and-fire (CIF) based model). The results on three public dataset and a large-scale dataset with 12000 hours of training data show that the two types of models have respective advantages that are consistent with their synchronous mode.
