Neural ODE with Temporal Convolution and Time Delay Neural Networks for Small-Footprint Keyword Spotting

1 Aug 2020arXiv:2008.00209archive 2025-07-28

Hiroshi Fuketa, Yukinori Morita

In this paper, we propose neural network models based on the neural ordinary differential equation (NODE) for small-footprint keyword spotting (KWS). We present techniques to apply NODE to KWS that make it possible to adopt Batch Normalization to NODE-based network and to reduce the number of computations during inference. Finally, we show that the number of model parameters of the proposed model is smaller by 68% than that of the conventional KWS model.
