[0027] The voice interactive robot according to the first embodiment will be described below.

[0028] figure 1 is a schematic diagram showing the appearance of the voice interactive robot according to the first embodiment. Voice interaction robot 100 is used for home use, and is provided with image acquisition device 101 and 102 (such as CCD camera), sound input device 103 and 104 (such as microphone), distance sensor 105, remote control signal transmitter / receiver 109, indicator 106, and movable parts 107 and 108 (such as robot arms).

[0029] Voice input devices 103 and 104 are arranged on the head of the voice interactive robot 100 and convert a user's voice (voice) into an analog signal. The converted analog signal is amplified by a microphone amplifier having a gain adjustment function, converted into a digital signal by an A / D converter (not shown), and processed by a processor (not shown) as sound data.

[0030] The distance sensor 105 is a device for measuring a di...

[0133] A voice interactive robot according to a second embodiment will be described below.

[0134] Figure 11 is a functional block diagram of the voice interactive robot according to the second embodiment.

[0135] The voice interactive robot 100 according to the second embodiment also has a function of recognizing users, and is characterized by switching the used DB for each recognized user.

[0136] Such as Figure 11 As shown, the voice interactive robot 100 is provided with an image input module 310 and a user identification module 311 .

[0137] The image input module 310 includes the image pickup devices 101 , 102 . An image of the user 210 in front of the voice interactive robot 100 is captured by the image pickup device 101 and output as input image data.

[0138] The user identification module 311 identifies the user 201 through the image input by the image input module 310 . The user recognition module 311 may use a direct method of recognizing a user by perfo...

Abstract

A voice recognition apparatus includes: a voice recognition module that performs a voice recognition for an audio signal during a voice period; a distance measurement module that measures a current distance between the user and an voice input module; a calculation module that calculates a recommended distance range, in which being estimated that an S/N ratio exceeds a first threshold, based on the voice characteristic; and a display module that displays the recommended distance range and the current distance.

Description

[0001] Cross References to Related Applications [0002] This application is related to subject matter contained in Japanese Patent Application Application No. 2008-035126 filed on Feb. 15, 2008, the entire contents of which are hereby incorporated by reference. technical field [0003] The present application relates to a voice recognition device, and a method for performing voice recognition. Background technique [0004] Generally, there is known a robot that performs voice interaction with a user, which is called a voice interactive robot. However, the voice interactive robot may not correctly recognize the voice uttered by the user due to noise output from various devices in an actual environment such as a home or an office in some cases. In order to improve the sound recognition rate in an environment where noise is generated by home appliances or user's actions, it is preferable for the user to input sound into the microphone with an appropriate intensity.
