Sound output device for obtaining sound setting information using space information and controlling method thereof

A method of controlling a sound output device, the method comprising:

• based on receiving user identification information, receiving from a server perceived sound information corresponding to the user identification information;
• outputting a first sound;
• based on receiving a signal corresponding to the first sound from a remote control device, obtaining sound setting information corresponding to the sound output device by inputting into a neural network model first device information stored in a memory of the sound output device, the signal corresponding to the first sound, and the perceived sound information;
• setting the sound output device according to the sound setting information, and
• outputting a second sound after the sound output device is set according to the sound setting information,
• wherein the sound setting information is an output of the neural network model, and
• wherein a signal corresponding to the second sound received from the remote control device comprises perceived characteristics which correspond to perceived characteristics according to the perceived sound information.

A sound output system comprising:

• a remote control device comprising a microphone;
• and
• a sound output device comprising:
• at least one memory storing one or more instructions and first device information of the sound output device;
• a communication interface comprising circuitry;
• a speaker;
• and
• one or more processors configured to:
• based on receiving user identification information, receive perceived sound information corresponding to the user identification information from a server through the communication interface;
• control the speaker to output a first sound;
• based on receiving a signal corresponding to the first sound from the remote control device, obtain sound setting information corresponding to the sound output device by inputting into a neural network model the first device information, the signal corresponding to the first sound, and the perceived sound information;
• set the sound output device according to the sound setting information;
• and
• control the speaker to output a second sound after the sound output device is set according to the sound setting information,
• wherein the sound setting information is an output of the neural network model, and
• wherein a signal corresponding to the second sound received from the remote control device comprises perceived characteristics which correspond to perceived characteristics according to the perceived sound information.
