Wearable electronic apparatus and method for controlling thereof

A wearable electronic apparatus worn on user's ears, the wearable electronic apparatus comprising:

• a memory configured to store at least one instruction;
• an inertial measurement unit (IMU) sensor;
• and
• a processor which is, by executing the at least one instruction stored in the memory, configured to
• control the IMU sensor to receive a bone conduction signal corresponding to vibration generated in the user's face while the wearable electronic apparatus is operated in an active noise cancellation (ANC) mode,
• based on analyzing an energy of the bone conduction signal while the wearable electronic apparatus is operated in the ANC mode, identify a dialog situation or a humming situation,
• based on identifying a presence of the dialog situation while the wearable electronic apparatus is operated in the ANC mode, control an operation mode of the wearable electronic apparatus to be a different operation mode from the ANC mode,
• while the wearable electronic apparatus is operated in the different operation mode, identify the dialog situation or the humming situation based on the bone conduction signal,
• based on an absence of the dialog situation being identified for a predetermined time while the wearable electronic apparatus is operated in the different operation mode, control the different operation mode to return to the ANC mode, and
• based on the presence of the dialog situation being identified within the predetermined time while the wearable electronic apparatus is operated in the different operation mode, control the different operation mode to be maintained.

A non-transitory computer-readable storage medium storing at least one instruction which, when executed by a processor of a wearable electronic apparatus, causes the processor to execute a method including:

• receiving, by an inertial measurement unit sensor of the wearable electronic apparatus, a bone conduction signal corresponding to vibration generated in the user's face, while the wearable electronic apparatus is operated in an active noise cancellation (ANC) mode;
• based on analyzing an energy of the bone conduction signal while the wearable electronic apparatus is operated in the ANC mode, identifying a dialog situation or a humming situation;
• based on identifying the dialog situation while the wearable electronic apparatus is operated in the ANC mode, controlling an operation mode of the wearable electronic apparatus to be a different operation mode from the ANC mode;
• while the wearable electronic apparatus is operated in the different operation mode, identifying the dialog situation or the humming situation based on the bone conduction signal;
• based on an absence of the dialog situation being identified for a predetermined time while the wearable electronic apparatus is operated in the different operation mode, controlling the different operation mode to return to the ANC mode;
• and
• based on a presence of the dialog situation being identified within the predetermined time while the wearable electronic apparatus is operated in the different operation mode, controlling the different operation mode to be maintained.
