Consumers have become comfortable using voice to interface with higher-end electronic device such as mobile phones and home automation appliances. While convenient, reliable and now commonplace, voice recognition historically is relatively high-power in the 10s of milliamp range requiring mains supply or daily recharging. This paper describes in detail new innovation that enables adding ultra-low voice commands to small, battery-powered medical, fitness and other wearable products. Combing optimized silicon and a light-weight recognizer algorithm, voice commands can now be added requiring just micro-amps that thus enabling continuous operation approaching one year from common batteries. The technical process and engineering trade-offs of adding voice commands to battery-powered wearable products will be presented.
