Acoustic-aware Non-autoregressive Spell Correction with Mask Sample Decoding

Ruchao Fan, Guoli Ye, Yashesh Gaur +1

Masked language model (MLM) has been widely used for understanding tasks, e.g. BERT. Recently, MLM has also been used for generation tasks. The most popular one in speech is using…

Towards Better Meta-Initialization with Task Augmentation for Kindergarten-aged Speech Recognition

Yunzheng Zhu, Ruchao Fan, Abeer Alwan

Children's automatic speech recognition (ASR) is always difficult due to, in part, the data scarcity problem, especially for kindergarten-aged kids. When data are scarce, the model…
