Embodiment 1

[0048] Such as figure 1 As shown, a method for assisting voice command recognition based on location information includes the following steps:

[0049] 3.1.1 Preprocessing results of the voice interaction content of personnel mainly carry out semantic recognition based on voice information to obtain semantic information;

[0050] For example, if a person sends out a voice command message of "close the car window", the voice message does not exclude that it has been pre-processed, such as noise reduction, amplification, etc. Semantic recognition is carried out according to the voice information, and semantic information is obtained. The semantic recognition method can be obtained by utilizing the existing semantic recognition method, and will not be repeated here.

[0051] Determine the location information of the personnel 3.1.2, the location information of the personnel will be given through the external system.

[0052] Such as figure 2 As shown in the figure, set the p...

Embodiment 2

[0078] Because of the accuracy problem, when a microphone array cannot accurately identify the position, one or more microphone arrays can be added to assist in identifying the position, and the position is finally determined according to the matching coefficient of different microphone arrays. for example Figure 5 Shown is a classic 2+2+3 commercial vehicle layout and microphone array 2 is added in addition to microphone array 1, which may be limited by system performance. The vector identified by microphone array 1 and θ in the figure 1 and θ 2 may not be accurately compared, it can assist in the identification of vectors in the microphone array 2 as well as Judgment is made to pinpoint whether the speech sound source is from the right middle position or the right rear position.

[0079] The specific execution steps are as follows:

[0080] According to the relative position of the microphone array and the determined position in the limited space, geometrically determ...

Abstract

The invention discloses a voice instruction identification method based on positional information, comprising the steps that semantic identification is conducted based on voice information, obtainingsemantic information; the position information of people sending out voice can be determined, and the sub-area in the limited space can be determined based on the position information of people, and different sub-areas are provided with different operation scopes and authorities, and interaction intention is obtained through the combination of semantic information, and an operation instruction canbe generated. The invention is advantageous in that the voice interaction information lack of accurate directing can be processed; the determination of the voice interaction intention can be assisted; voice interaction can be effectively and rapidly carried out.

Description

technical field [0001] The invention belongs to the technical field of voice recognition processing, and in particular relates to a method and device for assisting voice command recognition based on position information, using vague sentences to accurately interact with equipment in vehicles. Background technique [0002] With the development of the automobile industry and the maturity of the electronic market, vehicle-mounted intelligent terminals have gradually become important supporting equipment for automobiles. In recent years, economic prosperity has also led to a sharp increase in the number of domestic cars, and people's travel habits have also changed accordingly, and people and cars spend more and more time together. Therefore, the function of the vehicle-mounted intelligent terminal has also changed from a simple driving navigation to a multi-functional direction. [0003] Among the many newly developed functions, the recognition and execution of voice commands ...
