Automatic volume control for land mobile radio

The present disclosure provides a radio and method for automatically adjusting, in response to ambient noise, the volume setting of a radio. The radio comprises a microphone for receiving ambient audio and generating a microphone signal; a codec for receiving the microphone signal and generating a processor signal representative of the ambient audio; and processor circuitry operable to receive the processor signal, determine an ambient audio level in response to the processor signal, and determine an adjusted radio volume to generate a radio volume control signal, wherein the adjusted radio volume is determined by calculating a difference between a baseline volume level and ambient audio level and adding a current volume level setting, wherein the codec is also operable to receive the radio volume control signal and generate an output signal to adjust the radio volume setting to maintain a net difference between the adjusted radio volume and ambient audio.

Context based volume adaptation by voice assistant devices

A method includes detecting an input that triggers a virtual assistance (VA) on an electronic downdevice (ED) to perform a task that includes outputting audio content through a speaker associated with the ED. The method includes identifying a type of the audio content to be outputted through the speaker. The method includes determining whether a registered user of the ED is present in proximity to the ED. Each registered user is associated with a unique user identifier. The method includes, in response to determining that no registered user is present in proximity to the ED, outputting the audio content via the speaker at a current volume level of the ED. The method includes in response to determining that a registered user is in proximity to the ED, outputting the audio content at a selected, preferred volume level based on pre-determined or pre-established volume preference settings of the registered user.
