Devices and methods are disclosed for trusted listening. In some examples, an apparatus can include an audio receiving device having a microphone configured to capture sound and produce an audio signal, a processing unit configured to add a trusted signature to the audio signal, and an output configured to provide the audio signal. Further, a method of trusted listening can receive a first audio signal representing a real-time sound, generate a trusted signature in an audible format, and produce a second audio signal including the trusted signature.
