Deformed example 1

[0136] In addition, in the above-mentioned embodiment, the example which set the language of "request" as a trigger was shown. However, the information processing device 10 may also prepare a plurality of other triggers (trigger words) as triggers.

[0137] Figure 8A as well as Figure 8B It is an explanatory drawing of the voice recognition of this modification. For example, assume a case where voice recognition is performed on the voice signal 41 "request to turn on the air conditioner and set the temperature to 28° C." by the utterance of the user U. In addition, it is assumed that "request" and "setting" in the voice signal 41 are triggers.

[0138] In this case, the detection unit 12B reads the audio signal 41 from the beginning in chronological order, and executes trigger detection processing (see arrow A20 ). The detection unit 12B detects the trigger “request” when reading the trigger sound interval of the trigger “request” in the audio signal 41 . The voice reco...

Deformed example 2

[0143] In addition, in the case where the estimation of the speaker of the utterance is possible, the information processing device 10 may prepare a combination of a trigger and a speaker in advance. The speaker estimation refers to identifying the person who uttered the voice signal from the voice signal acquired by the voice acquisition unit 12A. By preparing the combination of trigger and speaker in advance by the control unit 12, even when the same trigger word is uttered, it is possible to change the dictionary used for voice recognition (voice recognition dictionary with trigger) in the case of different speakers. 26B, voice recognition dictionary 26C).

[0144] In addition, the information processing device 10 may enable or disable the voice recognition result according to speaker information by separately having a combination of a trigger and a speaker. For example, the control unit 12 may directly output, as a control signal, the recognition result of a speaker corre...

Abstract

An information processing apparatus, an information processing method, and a computer program product are provided. Voice recognition enhancement is achieved. The information processing apparatus 10 includes a detection unit 12B and a voice recognition unit 12C. The detection unit 12B detects a trigger from a voice signal 40, the trigger indicating start of voice recognition. The voice recognitionunit 12C uses a voice recognition dictionary 26B with a trigger corresponding to the detected trigger to perform voice recognition on a subsequent recognition voice section including the triggered trigger voice section.

Description

technical field [0001] Embodiments of the present invention relate to an information processing device, an information processing method, and a recording medium. Background technique [0002] Voice recognition devices that recognize commands from users and operate devices are put into practical use. In such a device, when a trigger indicating start of voice recognition such as utterance based on a specific keyword is detected, subsequent voice recognition is performed. [0003] However, conventionally, in the case of continuous utterances, detection of a trigger and voice recognition of a voice uttered after the trigger may not be possible. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2015-194766 Contents of the invention [0007] The problem to be solved by the present invention relates to an information processing device, an information processing method, and a recording medium capable of improving ...
