Abstract: Aspects presented herein may enable a wireless device to dynamically change the frequencies of its pilot tones based on the distance of one or more objects detected, thereby enabling the wireless device to utilize the advantages of both high frequency pilot tone and low frequency pilot tone. In one aspect, a wireless device transmits a first pilot tone at a first frequency. The wireless device detects whether there is an object within a specified distance of the wireless device based on a reflected signal of the first pilot tone. The wireless device transmits a second pilot tone at a second frequency based on at least one object being detected within the specified distance, where the second frequency is higher than the first frequency. The wireless device calculates a first distance of the at least one object with respect to the wireless device based the second pilot tone.

Abstract: A hearing aid device and methods implemented in hearing aid devices activate a radio frequency (RF) transceiver for communicating sounds signals for remote processing on a mobile computing device in response to the device detecting reception of meaningful sound, such as speech. Selectively activating the RF transceiver when sound is meaningful and avoiding powering the RF transceiver when detected sound is of little value to the wearer enables hearing aid to use the mobile computing device to process meaningful sound signals (e.g., speech from another person) while conserving batter power, thereby prolonging its battery life. The hearing aid device and methods may also deactivate the RF transceiver when the hearing aid device does not detect a meaningful sound signal.

Abstract: A processor-implemented method for recognizing a natural language on a mobile device includes receiving an audio input. The method further includes using a neural network to generate local text corresponding to the audio input. The method still further includes generating a local confidence value for accuracy of the local text. The method includes transmitting, to a remote device, data corresponding to the audio input. The method further includes receiving remote text corresponding to the data, along with a remote confidence score for accuracy of the remote text. The method still further includes outputting the local text in response to the local confidence value being higher than the remote confidence score, and outputting the remote text in response to the remote confidence score being higher than the local confidence value.
