Abstract: An information processing device (1) according to the present disclosure includes a storage unit (3), an acquisition unit (41), a calculation unit (42), and a processing unit (43). The storage unit (3) stores position information of a destination and sound information corresponding to the destination. The acquisition unit (41) acquires position information of a user. The calculation unit (42) calculates a distance from the user to the destination on the basis of the position information of the destination and the position information of the user. According to the distance, the processing unit (43) switches a virtual point sound source and a virtual surround sound source and causes the sound information to be output.

Abstract: [Object] To provide a new guide method in voice guidance that is capable of coping with even inaccuracy in an obtained user orientation. [Solving Means] An information processing apparatus according to the present technology includes a control unit. The control unit predicts a user orientation, performs voice guidance that guides a user to a destination on a route to the destination on the basis of the predicted user orientation, calculates a degree of reliability of the user orientation, and switches a method for guiding the user in the voice guidance on the basis of the degree of reliability.
