Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a voice command recognition system (VCR). An example embodiment operates by receiving a voice command directed to controlling a device, the voice command including a wake command and an action command. An amplitude of the wake command is determined. A gain adjustment for the voice command is calculated based on a comparison of the amplitude of the wake command to a target amplitude. An amplitude of the action command is adjusted based on the calculated gain adjustment for the voice command based on the comparison of the amplitude of the wake command to the target amplitude. A device command for controlling the device is identified based on the action command comprising the adjusted amplitude. The device command is provided to the device.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a voice control device including a microphone, a mute control, and a push-to-talk (PTT) control. An example embodiment operates by: entering a mute state from an always-listening state when the device receives a mute control signal; entering a PTT state from the mute state when the device is in the mute state and receives a first PTT control signal; activating the microphone when the device is in the PTT state; and entering the mute state from the PTT state when the device is in the PTT state and receives a second PTT control signal.
