摘要： Headphone providing fully natural interface are described. According to one aspect of such headphones, the headphones comprises a microphone configured for capturing an ambient sound, a speaker configured for playing audio signals, a command interface configured for receiving one or more external control commands, and a control unit having an ambient sound monitoring function. The control unit captures the ambient sound through the microphone, and automatically causes the headphones to enter an interactive mode when a preset interested sound is detected to appear in the ambient sound. The control unit controls the headphones to output an interactive reminder in the interactive mode, and the interactive reminder comprises one or more of visual reminders, a tactile reminder and an auditory reminder. Thus, interaction between the user and the ambience can be realized in a fully natural interface manner according to user preferences.

摘要： Techniques for controlling a personalized Bluetooth device (e.g., headset) and a voice interaction control method thereof are described. According to one aspect of the present invention, the Bluetooth device is caused to maintain a voice contact list. Each item in the voice contact list corresponds to a phone number associated with a set of audio data (e.g., a voice or a predefined audio). Instead of dialing a phone number on a calling device (e.g., a cellular phone) being paired with the Bluetooth device, a user can speak to the Bluetooth device that is caused to search a corresponding phone number in the voice contact list. The number is then sent to the calling device to make a call.
