## Abstract

An assistance system includes an assistance device configured to assist movement of a care receiver; a microphone provided on the assistance device; a speech analyzer configured to analyze speech of at least one of a caregiver or the care receiver included in sound data acquired by the microphone and acquire information related to an action; an echo analyzer configured to analyze an echo included the sound data and acquire information related to a location; and an action history information generator configured to generate action history information of at least one of the caregiver or the care receiver based on the information related to the action and the information related to the location.

## Claims

### Claim 1

An assistance system comprising:
an assistance device configured to assist movement of a care receiver;
a microphone provided on the assistance device;
a speech analyzer configured to analyze speech of at least one of a caregiver or the care receiver included in sound data acquired by the microphone and acquire information related to an action;
an echo analyzer configured to analyze an echo included the sound data and acquire information related to a location; and
an action history information generator configured to generate action history information of at least one of the caregiver or the care receiver based on the information related to the action and the information related to the location.

### Claim 2 (depends on 1)

The assistance system according to claim 1, wherein
the speech analyzer is configured to acquire the information related to the action by, based on a result of speech recognition processing on the sound data, identifying at least one of the care receiver and the caregiver and identifying an assistance operation for the care receiver.

### Claim 3 (depends on 2)

The assistance system according to claim 2, wherein
the speech analyzer is configured to, by detecting a specified keyword included in the result of the speech recognition processing, identify at least one of the care receiver and the caregiver and identify the assistance operation.

### Claim 4 (depends on 3)

The assistance system according to claim 3, wherein
the speech analyzer is configured to detect the keyword included in the result of the speech recognition processing based on detection word information registered as the keyword in at least one of a name of the care receiver, a name of the caregiver, a name of an item related to the assistance operation, and a name or verb of an operation performed by the care receiver during the assistance operation.

### Claim 5 (depends on 3)

The assistance system according to claim 3, wherein
the speech analyzer is configured to, in a case in which a restriction word included in restriction word information that is registered in advance is detected from the result of the speech recognition processing, restrict identifying of the assistance operation or restrict identifying of at least one of the care receiver and the caregiver for a series of conversations including the restriction word based on a detection result of the keyword.

### Claim 6 (depends on 1)

The assistance system according to claim 1, wherein
the speech analyzer is configured to acquire the information related to the action by identifying at least one of the care receiver and the caregiver based on a voiceprint extracted from the sound data and voiceprint information representing a voiceprint of the caregiver or a voiceprint of the care receiver.

### Claim 7 (depends on 1)

The assistance system according to claim 1, wherein
the echo analyzer is configured to acquire the information related to the location by identifying a room where the microphone recorded the speech based on a reverberation time or a frequency of a specified repeated sound in the sound data.

### Claim 8 (depends on 1)

The assistance system according to claim 1, wherein
the assistance device, in addition to assisting various operations including a standing operation and a sitting operation of the care receiver, records an operation history in log data, and
the care system is further provided with
a log data analyzer configured to acquire the information related to the action by identifying the assistance operation of the care receiver based on the log data.

### Claim 9 (depends on 8)

The assistance system according to claim 8, wherein
the log data analyzer is configured to detect a transfer operation performed in order of the standing operation and the sitting operation so as to transfer the care receiver or a movement between different rooms in the log data, and to identify the assistance operation based on a result of the detection of the transfer operation.

### Claim 10 (depends on 1)

The assistance system according to claim 1, further including
a fixed microphone provided in a room or a corridor in the care facility in which the assistance operation is performed,
wherein
the speech analyzer and the echo analyzer are configured to analyze sound data acquired by the fixed microphone.

### Claim 11 (depends on 1)

The assistance system according to claim 1, further including
a report generator configured to generate an assistance report including contents of assistance operations received by the care receiver based on the action history information generated by the action history information generator.

### Claim 12 (depends on 11)

The assistance system according to claim 11, wherein
the report generator is configured to generate the assistance report for each of multiple of the care receivers, and
the assistance system further includes
a report sending section configured to send the assistance report related to the care receiver to a terminal device possessed by a person concerned with the care receiver.
