Information processing device and information processing method

An information processing apparatus, comprising:

• a processor that:
• obtains audio information on a user learning a first language;
• estimates a voice production condition representing conditions of a jaw and a tongue of the user by analyzing the audio information;
• and
• causes a display to display:
• a plurality of voice production condition images in animated display, in accordance with a time-series change of the estimated voice production condition, and
• a first feature point, a second feature point, and a real-time feature point all superimposed on the plurality of voice production condition images in the animated display, wherein
• the processor identifies the first feature point in accordance with the voice production condition observed when a first sound in the first language is pronounced,
• the processor identifies the second feature point in accordance with the voice production condition observed when a second sound similar to the first sound is pronounced in a second language different from the first language,
• the processor identifies the real-time feature point in accordance with the voice production condition estimated by analyzing the audio information corresponding to a real-time voice production condition of the user, and
• the processor performs display processing that recommends to the user a change from a state where the real-time feature point is in a position corresponding to the second feature point to a state where the real-time feature point is in a position corresponding to the first feature point.
