Disclosed are various examples for audio data leak prevention using user and device contexts. In some examples, a voice assistant device can be connected to a remote service that provides enterprise data to be audibly emitted by the voice assistant device. In response to a request for the enterprise data being received from the voice assistant device, an audio signal can be generated that audibly broadcasts the enterprise data. The audio signal can be generated to audibly redact at least a portion of the enterprise data based at least in part on a mode of operation of the voice assistant device. The voice assistant device can be directed to emit the enterprise data through a playback of the audio signal.
