The Nest Audio smart speaker is controlled by voice, which makes it easy to play audio files, control smart homes or get answers from Google. Thanks to the power of Google Assistant and ongoing feature updates, Nest Audio will optimise itself over time. In addition, the speaker is able to adapt to the acoustics of the surrounding environment and to the genre of music. With regard to data protection, the integrated microphone can also be switched off manually on the device and the history can be deleted by voice command.
