Description

CROSS REFERENCE TO RELATED APPLICATION The present application claims the benefit of and priority to Korean Patent Application No. 10-2024-0153410 filed on Nov. 1, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to an electrified vehicle and a method of controlling the same. The electrified vehicle and the method manage a state of charge (SOC) of a battery for smooth operation of an audio control function. BACKGROUND In recent years, audio control functions have been actively applied to vehicles. The audio control functions include the function of outputting audio guidance and inputting voice commands that involves inputting a destination into a navigation system through a driver's voice. The audio control functions include the function of outputting turn-by-turn guidance through voice when giving directions. In the audio control functions, ambient noise may affect the operation performance due to the nature of the audio control functions, which involves outputting audio and receiving voice commands. For example, if ambient noise interferes while audio guidance is being output, a vehicle user such as a driver may have difficulty recognizing the content of the audio guidance. If ambient noise interferes while the vehicle user is inputting a voice command, the ambient noise may act as an unwanted sound in the command and may prevent the accurate input of the command. Therefore, functions to control ambient noise in various ways may be applied for smooth operation of the audio control functions. For example, in an electrified vehicle such as a hybrid vehicle or an electric vehicle, the execution of the audio control functions may involve control to reduce ambient noise by adjusting an operating point of a power source or a driving mode depending on the power source. However, as a state of charge (SOC) of a battery may act as a constraint on such control to reduce ambient noise, it is necessary to ensure that the SOC of the battery is sufficiently secured prior to an audio control execution so as to enable a smooth execution of ambient noise reduction control during the execution of the audio control function. The matters described above as a background art are provided solely to facilitate a better understanding of the background of the present disclosure and should not be construed as an admission that they constitute a related art already known to those having ordinary skill in the art. SUMMARY OF THE DISCLOSURE An objective of the present disclosure is to provide an electrified vehicle and a method of controlling the same. The electrified vehicle and the method may secure in advance a state of charge (SOC) of a battery before executing noise reduction control for audio control. Technical objectives of the present disclosure are not limited to the technical objectives mentioned above, and other technical objectives not mentioned above should be clearly understood by those having ordinary skill in the art from the following description. According to an embodiment of the present disclosure, an electrified vehicle includes a motor. The electrified vehicle also includes a battery connected to the motor, the battery is configured to supply power to the motor by discharging, and the battery is configured to be charged using a driving force of the motor. The electrified vehicle also includes a controller configured to manage a state of charge (SOC) of the battery based on a predicted execution count of audio control. The audio control includes one or more of an audio guidance output or a voice command input. An embodiment of the present disclosure provides a method of controlling an electrified vehicle including a motor and a battery connected to the motor. The battery is configured to drive the motor by discharging, and the battery is configured to be charged using a driving force of the motor. The method includes managing a state of charge (SOC) of the battery, based on a predicted execution count of audio control. The audio control includes one or more of audio guidance output or voice command input. According to embodiments of the present disclosure as described above, by securing in advance the SOC of the battery before executing noise reduction control for audio control, it becomes possible to prevent a situation in which noise reduction control may not be smoothly executed due to insufficient SOC of the battery. In addition, because noise reduction control during audio control may operate smoothly through the secured SOC of the battery in advance, noise generated in a vehicle is reduced. Thus, the recognition rate of a voice command in the vehicle is enhanced, and it is easier for a driver to recognize voice guidance output from the vehicle. The effects which may be achieved in the present disclosure are not limited to the effects mentioned above, and other effects not mentioned above should be clearly appreciated from the following desc
