Lattice Semiconductor, working in ultra-low power, small form factor, customisable solutions, has announced the availability of human voice detection and command recognition IP for smartphones and other handhelds for the growing Internet of Things (IoT) category of devices. These IPs are implemented in the iCE40 family of mobile FPGAs, enabling manufacturers to improve the user experience of their mobile devices with new voice activation capabilities and by maximising battery life by minimising false wake-up triggers to the processor.
“Accurate and reliable voice detection and command recognition is important for today’s smartphones and other mobile devices, but sound processing with a power hungry processor quickly drains batteries when random sounds are misinterpreted as human speech,” said Joy Wrigley, product line manager, Lattice Semiconductor. “Further, user experience is diminished when devices do not properly capture commands. Lattice’s low power, near-zero latency voice solutions alleviate these issues so manufacturers can improve the reliability of their devices’ voice activated functions while extending battery life.”
The rapidly expanding number of IoT devices is projected to reach 26 billion by 2020 according to the analyst firm Gartner. Lattice’s new solutions are ideal for a growing number of these IoT devices, which must minimise power consumption while maximising sensor reliability and performance. Silicon samples and both voice IP are available immediately by contacting Lattice directly or going to the Latticesemi.com/voice webpage.
