Embodiment 1

[0122] In this embodiment, an electronic device all-in-one computer is taken as an example. At present, many all-in-one computers have voice recognition functions, for example, electronic devices are controlled by voice. Realize the purpose of automatically opening or closing the electronic device, and can also realize the purpose of automatically opening or closing the browser by making a voice "open / close the browser". And when an input operation is required, you only need to say the content to be searched, and the electronic device can receive and perform the recognition operation, and respond to the webpage. If the user sends out the voice "English learning", the browser will open the relevant information about English learning. web pages etc.

[0123] A camera and a microphone are installed on the motherboard of the all-in-one computer. When the voice recognition function of the electronic device is turned on, the camera will first locate the user through face recognition...

Embodiment 2

[0136] Please refer to image 3 , in this embodiment of the application, the image acquisition unit of the electronic device includes a first camera 301 and a second camera 302, and the sound acquisition unit of the electronic device also includes a first microphone 303 and a second microphone 304, wherein the first camera 301 , the second camera 302, the first microphone 303 and the second microphone 304 are respectively connected to the data processing unit 305, and the data processing unit 305 is used for processing the image data acquired by the image acquisition unit and the sound information acquired by the sound acquisition unit.

[0137] In the specific implementation process, the electronic device obtains the first image data of the sound output object (which may be a specific user or an unspecific user) through the first camera, and determines the first angle between the sound output object and the first camera value, and obtain the second image data of the sound out...

specific Embodiment approach

[0144] (1) When the sound acquisition unit has only one microphone, the center position between the first camera 301 and the second camera 302 can be taken as the reference position of the image acquisition unit, and the sound can be obtained by combining the values ​​of θ1, θ2, a, b, and c Outputting the distance value and angle value between the object and the reference position, that is, the first reference distance value and the first reference angle value. When the distance between the sound collection unit and the image collection unit is less than or equal to a preset distance (such as 50cm), the first reference distance value and the first reference angle value can be directly obtained as reference values ​​for speech recognition processing. When the distance between the sound collection unit and the image collection unit is greater than the preset distance, the position data of the sound collection unit can be obtained first, and further, the distance value and the ang...

Abstract

The invention discloses a data processing method and an electronic device, so as to solve the technical problem that in the case of large environmental noise in the prior art, a voice recognition system is hard to achieve a high recognition rate. The method comprises steps: target image data, acquired and obtained by an image acquisition unit, of a sound output object are acquired; on the basis of the target image data, a first reference distance value and a first reference angle value between the sound output object and a first position of the image acquisition unit are acquired; when a sound acquisition unit is located at a second position different from the first position, recognition processing is carried out on sound information of the environment of the sound output object acquired and obtained by the sound acquisition unit at least on the basis of the first reference distance value and the first reference angle value so as to acquire a voice recognition result.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a data processing method and electronic equipment. Background technique [0002] With the rapid development of electronic technology, speech recognition technology has also been rapidly developed and widely used. The purpose of speech recognition is to convert the vocabulary content in human speech into readable input for electronic devices, such as keys, binary codes or characters. sequence. Applications of voice recognition technology include voice dialing, voice navigation, indoor equipment control, voice document retrieval, simple dictation data entry, etc. [0003] Speech recognition methods are mainly pattern matching methods, including two stages of training and recognition. Whether it is training or recognition, the input speech must be preprocessed and feature extracted. The specific work done in the training stage is to input the training speech several...
