Abstract

Methods and systems are provided for ultra-low-power adaptive, user independent, voice triggering in electronic devices. A voice trigger, which may be configured as ultra-low-power function, may be run in an electronic device, when the electronic device transitions to a power-saving state, and may be used to control the electronic device based on audio inputs. The controlling may comprise capturing an audio input, and processing the audio input to determine when the audio input corresponds to a triggering command, to trigger transitioning of the electronic device from the power-saving state. The processing of audio input, to determine that it corresponds to the triggering command, may be based on use of an adaptively configured state machine. The state machine may be based on a Hidden Markov Model (HMM), and may be configured as a two-dimensional state machine that comprises plurality of lines of incantations, each of which corresponding to the triggering command.
