Recurrent neural network system based on Ultra-Low power neuron
Problem Statement

Traditional speech recognition methods often struggle with real-time processing, high computational needs, and poor performance in noisy environments. These limitations highlight the demand for a more accurate approach.

Abstract

An electronic device designed for speech recognition. It uses a special type of neural network called a recurrent spiking neural network (SNN). The network includes BTBT neurons, which process speech signals by converting them into electrical spikes. These neurons and their connections manage the signals, allowing the device to recognize and interpret speech effectively. The system includes components that shape and adjust these signals to improve accuracy. This invention enhances the ability of electronic devices to understand spoken words by mimicking how the brain processes speech.
