    Abstract: This disclosure generally pertains to volume control of audio output by a device. A piecewise curve may be used to implement volume control using two or more curves segments. The piecewise curve may be implemented by a signal converter. The curve segments may be selected to provide volume control that provides incremental changes in amplification at mid-level to high level volumes, while providing anticipated amplification at lower volumes which satisfy users' expectations. In some instances, different piecewise curves may be selected for different types of audio so that these different types of audio are provided to users at an expected volume and/or in a meaningful way. When multiple audio outputs occur at a same time, the piecewise curves associated with some of the audio outputs may be dynamically adjusted or updated based on the presence of the other ones of the multiple audio outputs and/or ambient noise.

    Abstract: A system may include first and second speech-processing systems. The first speech-processing system may process received audio data and determine that a command represented therein is associated with a second speech-processing system. The first speech-processing system may send command data to the second speech-processing system and receive response data in return. The first speech-processing system may then process the response data to determine second response data that includes an indication of the second speech-processing system and cause output of audio corresponding to the second response data.
