Abstract

An electronic apparatus of the present invention includes: a speech input section for converting an inputted speech to speech data; a speech recognition section for analyzing the speech data so as to identify a word or sentence in the speech data and calculate a certainty of the identified word or sentence; a response determining section for determining, in accordance with the certainty, whether to ask back to a user; and an asking-back section for asking back to the user, in a case where the certainty is less than a first threshold and not less than a second threshold, the response determining section determining that the electronic apparatus is going to ask back to the user, and in a case where the certainty is less than the second threshold, the response determining section determining that the electronic apparatus is not going to ask back.

Claims

1. An electronic apparatus comprising:

a speech input section for converting an inputted speech to speech data;

a speech recognition section for analyzing the speech data so as to (i) identify a word or sentence included in the speech data and (ii) calculate a certainty of the word or sentence that has been identified;

a response determining section for determining, in accordance with the certainty, whether it is necessary to ask back to a user or not; and

an asking-back section for asking back to the user,

(a) in a case where the certainty is less than a first threshold and not less than a second threshold, the response determining section determining that the electronic apparatus is going to ask back to the user, and (b) in a case where the certainty is less than the second threshold, the response determining section determining that the electronic apparatus is not going to ask back to the user.

2. The electronic apparatus as set forth in claim 1, wherein the response determining section selects, in accordance with the certainty, one of a plurality of patterns in which the asking-back section asks back to the user.

3. The electronic apparatus as set forth in claim 1, further comprising a communication section for transmitting the speech data to an external device and receiving, from the external device, a certainty of a word or sentence included in the speech data.

4. A cleaner comprising:

an electronic apparatus as set forth in claim 1; and

at least one of a self-propelling section with which the electronic apparatus propels itself, an air-blowing section for sucking dust, and a cleaning brush section for brushing and cleaning a floor.

5. The cleaner as set forth in claim 4, wherein the response determining section changes the second threshold while at least one of the self-propelling section, the air-blowing section, the cleaning brush section is being driven.
