Vehicle and method for controlling thereof

1. A vehicle, comprising: database configured to store a plurality of sound sources classified by types of emotions: a speaker; and a controller configured to:

output a landmark name based on a route guidance text included in a driving route information calculated by a navigation system;

output a ratio of a first emotion included in the plurality of emotions and a ratio of the second emotion included in the plurality of emotions;

select a first sound source from among the plurality of sound sources classified as the first emotion based on the ratio of the first emotion;

select a second sound source from among the plurality of sound sources classified as the second emotion based on the ratio of the second emotion;

determine a first playback period and a second playback period based on the ratio of the first emotion and the ratio of the second emotion;

output a first sound generated based on the first sound source during the first playback period;

and output a second sound generated based on the second sound source during the second playback period;

wherein the first playback period is determined to be longer than the second playback period when the ratio of the first emotion is higher than the ratio of the second emotion.

2. The vehicle according to claim 1 , wherein the controller is configured to output the landmark name included in the route guidance text using Natural Language Processing (NLP).

3. The vehicle according to claim 1 , wherein the controller is configured to determine the plurality of emotions corresponding to the landmark name using the landmark name as input data of a long short-term memory (LSTM).

4. The vehicle according to claim 1 , wherein the controller is configured to: determine a plurality of first target engine sound orders based on at least one of output torque, speed, and accelerator pedal pressure of the vehicle during the first playback period in which the first sound is output and synthesize the first sound based on the first sound source and the plurality of first target engine sound orders; and determine a plurality of second target engine sound orders based on at least one of output torque, speed, and accelerator pedal pressure of the vehicle during the second playback period in which the second sound is output and synthesize the second sound based on the second sound source and the plurality of second target engine sound orders.

5. The vehicle according to claim 4 , wherein the controller is configured to: select a first target engine sound order of some of the plurality of first target engine sound orders based on the ratio of the first emotion and the ratio of the second emotion, and synthesize the first sound based on the first sound source and the selected partial first target engine sound order, and

select a second target engine sound order of some of the plurality of second target engine sound orders based on the ratio of the first emotion and the ratio of the second emotion, and synthesize the second sound based on the second sound source and the selected partial second target engine sound order.

6. The vehicle according to claim 1 , wherein the controller is configured to determine volume of the first sound and the second sound based on at least one of an output torque, a speed, and an accelerator pedal pressure of the vehicle.

7. The vehicle according to claim 1 , wherein the first emotion and the second emotion are one of happiness, joy, sadness, vigor, fear, anger, or tranquility.

8. A controlling method of a vehicle including a database storing a plurality of sound sources classified by types of emotions, the method comprising:

outputting, by a controller, a landmark name based on a route guidance text included in a driving route information calculated by a navigation system,

determining by the controller, a plurality of emotions corresponding to the landmark name;

outputting, by the controller, a ratio of a first emotion included in the plurality of emotions and a ratio of a second emotion included in the plurality of emotions,

selecting, by the controller, a first sound source from among the plurality of sound sources classified as the first emotion based on the ratio of the first emotion, selecting a second sound source from among the plurality of sound sources classified as the second emotion based on the ratio of the second emotion,

determining, by the controller, a first playback period and a second playback period based on the ratio of the first emotion and the ratio of the second emotion, outputting a first sound generated based on the first sound source during the first playback period, and

outputting, by the controller, a second sound generated based on the second sound source during the second playback period;

wherein the first playback period is determined to be longer than the second playback period when the ratio of the first emotion is higher than the ratio of the second emotion.

9. The method according to claim 8 , wherein outputting the landmark name based on the route guidance text included in the driving route information calculated by the navigation system includes outputting the landmark name included in the route guidance text using Natural Language Processing (NLP).

10. The method according to claim 8 , wherein the determining the plurality of emotions corresponding to the landmark name includes determining the plurality of emotions corresponding to the landmark name using the landmark name as input data of a long short-term memory (LSTM).
