Keyword Spotting: Making an On-Device Assistant a Reality

Another option for keyword spotting is the Syntiant NDP101 chip.
While this device also operates at comparable low power (200 microwatts) it is a dedicated audio processor that integrates an audio front end, buffering and feature extraction together with the neural network. Syntiant expects to replace digital MACs with an in-memory analog circuit in the future to further reduce power.
The Akida chip has the added advantages of on-chip learning and versatility. It can also be reconfigured to perform sound or image classification, odor identification or to classify features extracted from data. Another advantage of local processing is that no images or data are exposed on the Internet, significantly reducing privacy risks
Syntiant previously used a Frankenstein (hybrid digital/analog) SNN:

... but they have progressed to all digital:
WO2020028693A1 SENSOR-PROCESSING SYSTEMS INCLUDING NEUROMORPHIC PROCESSING MODULES AND METHODS THEREOF
BrainChip's US2017229117A1 LOW POWER NEUROMORPHIC VOICE ACTIVATION SYSTEM AND METHOD was cited against this Syntiant patent application.
