Abstract
The use of speech-triggered wake-up interfaces has
grown significantly in the last few years for use in ubiquitous
and mobile devices. Since these interfaces must always be active,
power consumption is one of their primary design metrics.
This article presents a complete mixed-signal system-on-chip,
capable of directly interfacing to an analog microphone and
performing keyword spotting (KWS) and speaker verification
(SV), without any need for further external accesses. Through
the use of: 1) an in
