LOW POWER NEUROMORPHIC VOICE ACTIVATION SYSTEM AND METHOD
First Claim
1. A system for controlling an electronic device through voice control commands, the system comprising:
- a hierarchical arrangement of a first spiking neural network and a second spiking neural network, said first spiking neural network receives output spikes from an artificial cochlea, said first spiking neural network configured to recognize and learn spike patterns, in the output spikes, that indicates presence of a voice activity in the output spikes, and said first spiking neural network activates said second spiking neural network from a low energy halted or off state, if any voice activity is detected, in the output spikes, by said first spiking neural network.

Abstract
The present invention provides a system and method for controlling a device by recognizing voice commands through a spiking neural network. The system comprises a spiking neural adaptive processor receiving an input stream that is being forwarded from a microphone, a decimation filter and then an artificial cochlea. The spiking neural adaptive processor further comprises a first spiking neural network and a second spiking neural network. The first spiking neural network checks for voice activities in output spikes received from artificial cochlea. If any voice activity is detected, it activates the second spiking neural network and passes the output spike of the artificial cochlea to the second spiking neural network that is further configured to recognize spike patterns indicative of specific voice commands. If the first spiking neural network does not detect any voice activity, it halts the second spiking neural network.
