The present disclosure discloses a man-machine dialogue mode switching method, which is applicable to an electronic device. The method includes receiving a current user sentence spoken by a current user; determining whether a dialogue field to which the current user sentence belongs is a preset dialogue field; if yes, switching the current dialogue mode to a full-duplex dialogue mode; and if not, switching the current dialogue mode to a half-duplex dialogue mode. In the present disclosure, the dialogue mode is switched by determining whether the dialogue field to which the current user sentence belongs is the preset dialogue field, and the dialogue mode can be automatically switched and adjusted according to the difference of the dialogue fields, such that the man-machine dialogue is always in the most suitable dialogue mode and can be realized smoothly.

There is disclosed a communication device. The communications device includes an audio head unit for generating audio from an audio source, at least one speaker connected to the audio head unit for audibly generating audio provided by the audio head unit, and an intercom system, linked to the audio head unit, for receiving intercom audio for broadcast over one or more a wired or wireless intercom headset, and broadcasting the intercom audio for receipt by the one or more wired or wireless headset.
