Embodiment Construction

[0025] Embodiments of the present invention will be described with reference to the drawings.

[0026] The relevant utterance content identification device 10 of the present invention is for example a computer such as a mobile phone, such as figure 1 As shown, a CPU 12 , a storage unit 14 , an input unit 15 , and an output unit 19 are included.

[0027] The input unit 15 is a functional unit for inputting external information of the utterance content recognition device 10 to the CPU 12 , and includes a microphone 16 and a camera 18 in the present embodiment. The microphone 16 is, for example, a device capable of collecting sound, such as a directional microphone. The microphone 16 has directivity with respect to the sound collecting direction, and the CPU 12 can control the directivity. Specifically, the CPU 12 can control the directivity of the microphone 16 by controlling its posture. In addition, the microphone 16 converts the collected sound into an electrical signal, a...

Abstract

Speech recognition low in accuracy because the speaking person is not near the sound collector is prevented. A speech content recognizing device (10) is characterized in that a sound collector (16) for collecting sound, an imager(18) for imaging the speaking person speaking to the sound collector (16), a speech recognition function section(132) for recognizing the speech collected, and a recognition / learning judging section (142) for limiting the speech recognition by the speech recognition function section (132) if the captured image does not contain a speaking person image showing at least a part of the speaking person.

Description

technical field [0001] The invention relates to an utterance content recognition device and a utterance content recognition method. Background technique [0002] Voice recognition technology that converts voices into character strings is known. In this voice recognition technology, firstly, a microphone is used to collect the voice of the speaker. Next, the characteristic pattern of the collected sound is extracted. Then, a character string pattern corresponding to the extracted characteristic pattern is output as a recognition result, whereby the voice is replaced with a character string. [0003] In addition, Patent Document 1 describes that such a voice recognition technology is used in combination with a lip recognition technology that performs pattern recognition based on a characteristic pattern of a lip shape of a speaker. [0004] Patent Document 1: Japanese Unexamined Patent Publication No. 6-311220 [0005] However, in the above-mentioned conventional voice rec...
