Description

Electronic device with voice guidance function and voice guidance method using the electronic device

One embodiment of the present disclosure relates to an electronic device having a voice guidance function for the state of the electronic device and a voice guidance method by the electronic device.

As electronic devices become smarter, the number of electronic devices that notify the status of the electronic device using a user-friendly voice guidance signal instead of a simple sound is increasing. For example, when the refrigerator door is left open for more than a certain period of time, a refrigerator is being released that outputs a voice guidance signal saying "the door is open" instead of the alarm sound indicating the door is open.

However, in order to add a voice guidance function to an electronic device, the main board and memory of each electronic device must be changed. For example, in order to output a voice guidance signal such as “the door is open” from different electronic devices such as a refrigerator and an electric rice cooker, the main board and memory of each refrigerator and electric rice cooker must be changed.

Therefore, even when adding a simple voice guidance function, the main board and memory of the electronic device must be changed, making it difficult to add the voice guidance function to each electronic device. Even if the voice guidance function of the electronic device is broken, the main board and memory of the electronic device must be replaced, which may result in expensive repair costs.

Additionally, in order to reduce the distorted sound of the voice guidance signal caused by the cover that protects the electronic device, the electronic device must have a hole dedicated to the speaker on the cover. However, the lifespan of the speaker may be shortened due to dust and moisture entering the speaker dedicated hole located in the electronic device.

An electronic device according to an embodiment of the present disclosure may include a voice guidance output unit and at least one processor. The voice guidance output unit may include a speaker that outputs a voice guidance signal. At least one processor may control the operation of the electronic device. At least one processor includes a voice guidance output unit to output a modified voice guidance signal that reflects the distortion sound generated by the cover that protects the electronic device in the basic voice guidance signal, based on status information of the electronic device according to the operation of the electronic device. You can control it. At least one processor may be configured to cancel the distorted sound as the modified voice guidance signal passes through the cover and output the basic voice guidance signal to the outside of the electronic device.

A voice guidance method using an electronic device including a voice guidance output unit including a speaker for outputting a voice guidance signal and at least one processor according to an embodiment of the present disclosure includes operating the electronic device by the at least one processor. It may include a step of controlling. The voice guidance method according to an embodiment of the present disclosure is based on status information of the electronic device according to the operation of the electronic device by at least one processor, and uses a basic voice guidance signal as a distorted sound generated by a cover that protects the electronic device. It may include controlling the voice guidance output unit so that the modified voice guidance signal reflected in is output. The voice guidance method according to an embodiment of the present disclosure may be configured so that the modified voice guidance signal passes through the cover, the distorted sound is canceled out, and the basic voice guidance signal is output to the outside of the electronic device.
