BACKGROUND

1. Field

The present invention relates to a laundry treatment apparatus.

2. Background

In general, a laundry treatment apparatus refers to an apparatus capable of washing or drying laundry, or washing and drying the laundry. Herein, the laundry treatment apparatus may perform only a washing or drying function or may perform both washing and drying functions. Recently, a washing machine capable of performing a refresh function that removes creases, odor, static electricity, etc. by means of a steam supplier has been introduced.

A conventional laundry treatment apparatus has been equipped with a control panel disposed on the front surface or top surface of a cabinet to receive manipulation commands from the user. The control panel has been provided with a plurality of input portions for operating the laundry treatment apparatus so that the laundry treatment apparatus may perform a washing or drying course.

The input portion may be provided with a rotary switch, a button, or a touch panel that receives any one of a course or an option performed by the laundry treatment apparatus from the user. The control panel may transmit a command for executing the course or option input to the input portion to a controller to operate the laundry treatment apparatus according to setting of the course or the option.

Recently, a laundry treatment apparatus including a voice recognition unit installed in the input portion has emerged so that the voice recognition unit recognizes voice of the user to replace physical input, such as input through the rotary switch, button, or touch panel, with voice.

As such, the user may control the laundry treatment apparatus without physically touching the laundry treatment apparatus, so that user convenience and space utilization can be maximized.

However, such a voice recognition unit has very sensitively responded to vibrations because the voice recognition unit has been configured to receive vibrations generated from sound waves. Therefore, if vibrations occur in the case in which a drum of the laundry treatment apparatus rotates or water supply or drainage is performed in the laundry treatment apparatus, there has been a problem that the voice recognition unit cannot accurately recognize the voice of the user.

Thus, when the conventional laundry treatment apparatus is in operation, a recognition level of the voice recognition unit has been reduced.

In addition, even when vibrations generated from the exterior are transmitted to the conventional laundry treatment apparatus, the voice recognition unit has had difficulty in correctly recognizing the voice of the user.

Therefore, whenever the user controls the laundry treatment apparatus through voice, the user should have inconveniently confirmed whether the voice recognition unit has correctly recognized the voice of the user.
