1. A method of controlling a wearable audio device having active noise reduction (ANR) capabilities, the method comprising:
detecting a speech signal from a user wearing the wearable audio device, wherein the ANR is set to a first level;
in response to detecting the speech signal, determining whether the speech signal is not related to a purpose other than to speak with another person; and
in response to determining that the speech signal is not related to a purpose other than to speak with another person, automatically setting the ANR to a second level that allows the user to hear sounds external to the wearable audio device more audibly relative to the first level,
wherein determining whether the speech signal is not related to a purpose other than to speak with another person includes determining that the speech signal is not provided during a call that is unmuted.
