## Abstract

The information presentation device according to an embodiment includes: an acquisition unit configured to acquire a speech speed and a sound pressure of an utterance at a predetermined interval; a determination unit configured to determine whether at least one of the speech speed or the sound pressure needs to be improved or not; and a presentation content control unit configured to acquire a pseudo heartbeat sound in a case where it is determined that the speech speed needs to be improved, acquire a bubble noise in a case where it is determined that the sound pressure needs to be improved, and output presentation information including at least one of the pseudo heartbeat sound or the bubble noise.

## Claims

### Claim 1

An information presentation device, comprising:
acquisition circuitry configured to acquire a speech speed and a sound pressure of an utterance at a predetermined interval;
determination circuitry configured to determine whether at least one of the speech speed or the sound pressure needs to be improved or not; and
presentation content control circuitry configured to acquire a pseudo heartbeat sound in a case where it is determined that the speech speed needs to be improved, acquire a bubble noise in a case where it is determined that the sound pressure needs to be improved, and output presentation information including at least one of the pseudo heartbeat sound or the bubble noise.

### Claim 2 (depends on 1)

The information presentation device according to claim 1, wherein:
the presentation content control circuitry outputs the pseudo heartbeat sound to a first device and outputs the bubble noise to a second device.

### Claim 3 (depends on 1)

The information presentation device according to claim 1, further comprising:
a first voice output speaker and a second voice output speaker,
wherein the presentation content control circuitry outputs voice information from a listener of the utterance to the first voice output speaker and outputs the presentation information to the second voice output speaker.

### Claim 4 (depends on 1)

The information presentation device according to claim 1, wherein;
the presentation information is information obtained by synthesizing voice information from a listener of the utterance and at least one of the pseudo heartbeat sound or the bubble noise.

### Claim 5 (depends on 1)

The information presentation device according to claim 1, further comprising:
acquisition circuitry configured to acquire a heart rate of a user who is giving the utterance,
wherein the presentation content control circuitry acquires the pseudo heartbeat sound on the basis of the heart rate.

### Claim 6 (depends on 1)

The information presentation device according to claim 1, wherein;
the presentation content control circuitry outputs the presentation information until at least one of the speech speed or the sound pressure falls within a reference range.

### Claim 7

An information presentation method, comprising:
acquiring a speech speed and a sound pressure of an utterance at a predetermined interval;
determining whether at least one of the speech speed or the sound pressure needs to be improved or not;
acquiring a pseudo heartbeat sound in a case where it is determined that the speech speed needs to be improved;
acquiring a bubble noise in a case where it is determined that the sound pressure needs to be improved; and
outputting presentation information including at least one of the pseudo heartbeat sound or the bubble noise.

### Claim 8 (depends on 7)

A non-transitory computer readable medium storing an information presentation program for causing a processor to perform the method of claim 7.
