Abstract:
A smart-home device may include a recording device configured to record sound during a first time interval and a memory device comprising a plurality of stored sound profiles. The smart-home device may also include a processing system configured to receive an environmental input, select a stored sound profile from the plurality of stored sound profiles based on the environmental input, and perform a noise-cancelation routine on the sound recorded during the first time interval. The stored sound profile may be used as an initial background noise profile for the noise-cancelation routine.
Abstract:
A method for customizing speech-recognition dictionaries for different smart-home environments may include generating, at a smart-home device mounted in an enclosure, an acoustic impulse response for the enclosure. The method may also include receiving, by the smart-home device, an audio signal captured in the enclosure. The method may additionally include performing, by the smart-home device, a speech-recognition process on the audio signal using a second speech dictionary generated by convolving the acoustic impulse response with a first speech dictionary.
Abstract:
Embodiments of the present disclosure provide methods and systems for enabling remote alarm hushing with acoustic presence verification. Acoustic presence verification is used to assure that a device attempting to remotely deactivate an alarm is located within a certain distance of an alarming device before allowing the alarm to be hushed. Acoustic presence can be established through emission and monitoring of ultrasonic acoustic signals. The ultrasonic acoustic signals may be transmitted at a frequency that exceeds human hearing such as, for example, between 18 KHz and 22 kHz. Such ultrasonic signals have a relatively short range and are unable to penetrate walls and floors, thus providing an effective tool for ensuring that the device attempting to remotely hush an alarming device is within a line-of-sight of the alarming device.
