Problems solved by technology

Since the user's voice needs to be recognized and analyzed after the entire segment of the user's voice is obtained, the delay in the entire control process is relatively long

example 1

[0220] Example 1, the voice signal sent by the user for the second time (that is, the first voice signal) is "stop". Figure 10 The exemplary voice control process includes the following steps:

[0221] Step 1, the voice control device determines that the text message "stop" has complete semantics;

[0222] Step 2, the voice control device determines that the text message "stop" has a contextual relationship with the text message "open the window".

[0223] Step 3, the voice control device determines that the preset set corresponding to the structured information "control-window.adjust" includes the text information "stop", and determines that the preset instruction corresponding to the text information "stop" is identified as "window stop", according to The preset command flag "window stop" defines the window stop command.

example 2

[0224] Example 2, the voice signal sent by the user for the second time (that is, the first voice signal) is "just tune here", refer to Figure 11 The exemplary voice control process includes the following steps:

[0225] Step 1, the voice control device determines that the text information "just" does not have complete semantics;

[0226] Step 2, the voice control device determines that the text message "just call" does not have complete semantics;

[0227] Step 3, the voice control device determines that the text message "Just tune in" does not have complete semantics;

[0228] Step 4, the voice control device determines that the text message "just tune here" has complete semantics;

[0229] Step 5, the voice control device determines that the text message "just tune here" has a contextual relationship with "open the window".

[0230] In step 6, the voice control device determines that the preset set corresponding to the structured information "control-window.adjust" does...

example 3

[0234] Example 3, the voice signal sent by the user for the second time (that is, the first voice signal) is "play music", refer to Figure 12 The exemplary voice control process includes the following steps:

[0235] Step 1, the voice control device determines that the text message "broadcast" does not have complete semantics;

[0236] Step 2, the voice control device determines that the text message "play" does not have complete semantics;

[0237] Step 3, the voice control device determines that the text information "playing sound" does not have complete semantics;

[0238] Step 4, the voice control device determines that the text message "play music" has complete semantics;

[0239] In step 5, the voice control device determines that the text information "play music" and "open the car window" do not have a contextual relationship.

[0240] The voice control device performs semantic analysis, dialogue management, etc. according to "playing music", and updates the convers...

Abstract

The invention discloses a voice control method and device, which are used for solving the problem of long time delay in an existing voice control process. The method comprises the following steps: determining first text information with complete semantics according to a first voice signal; according to the first text information and second text information, controlling target equipment to be switched in the specified running states, wherein the second text information is obtained before the first text information, the second text information is used for controlling the target equipment to enter a first running state in the specified running states, and the second text information and the first text information have a contextual relationship.

Description

technical field [0001] The present application relates to the field of automatic driving, in particular to a voice control method and device. Background technique [0002] Voice interaction products have widely entered people's daily life, such as smart phones, smart home equipment, smart vehicle equipment and other products have voice interaction functions. Especially in the vehicle environment, voice interaction can free hands, and has the characteristics of fast command control and safe driving. [0003] During driving, due to changes in the driving environment, the user can usually perform voice interaction with the vehicle-mounted voice control device to adjust the opening of vehicle-mounted devices such as windows and sunroofs. [0004] However, in the current voice interaction process, the voice control device needs to confirm that the user has finished sending the voice signal, and then perform voice recognition and semantic analysis based on the entire acquired use...
