Abstract
A system and method of keyword spotting using two neural networks is disclosed. The system is in sleep mode most of the time, and wakes up periodically. Upon waking, a limited duration of audio is examined. This may be performed using an auxiliary neural network. If any audio activity is detected in this duration, the system fully wakes and examines a longer duration of audio for keywords. The keyword spotting is also performed by the main neural network, which may be a convolutional neural network (CNN).
