摘要:
In a mobile device, a bone conduction or vibration sensor is used to detect the user's speech and the resulting output is used as the source for a low power Voice Trigger (VT) circuit that can activate the Automatic Speech Recognition (ASR) of the host device. This invention is applicable to mobile devices such as wearable computers with head mounted display, mobile phones and wireless headsets and headphones which use speech recognition for the entering of input commands and control. The speech sensor can be a bone conduction microphone used to detect sound vibrations in the skull, or a vibration sensor, used to detect sound pressure vibrations from the user's speech. This VT circuit can be independent of any audio components of the host device and can therefore be designed to consume ultra-low power. Hence, this VT circuit can be active when the host device is in a sleeping state and can be used to wake the host device on detection of speech from the user. This VT circuit will be resistant to outside noise and react solely to the user's voice.

Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.

A digital enhanced cordless telecommunication (DECT) base station, the DECT base station includes a transmitter that is arranged to transmit, at different points of time, downlink transmitted DECT signals to another DECT device that differs from the DECT base station; a receiver that is arranged to receive from the other DECT device downlink reception information indicative of attributes of downlink received DECT signals that were received by the other DECT device as a result of the transmission of the downlink transmitted DECT signal; a processor that is arranged to process the downlink reception information to detect a motion that affects a reception of the downlink received DECT signals by the other device.
