HYBRID VEHICLE AND METHOD OF SUPPORTING AUDIO INPUT/OUTPUT FOR THE SAME

The present disclosure relates to a hybrid electric vehicle in which powertrain noise may be controlled to improve the voice command recognition performance of the vehicle control system and also improve the driver’s experience with the audio guidance system, and a method for supporting audio input/output function for the same. A method of supporting audio input/output for a hybrid electric vehicle may include: determining a first condition for audio input/output function and a second condition for inside noise level; and performing a noise reduction control by inducing an engine-off state based on a current drive mode and further based on the first and the second conditions being satisfied.
