Problems solved by technology

During the interaction process with the user, the existing vehicle-mounted voice control system can only recognize and execute one command word action at a time, which cannot meet the needs of the user to perform multiple actions at one time. Voice commands are used for matching processing, the matching accuracy is low, and the interactivity is poor

Embodiment 1

[0092] Due to the limited size of the command word database of the existing vehicle-mounted voice control system and inconvenient real-time update, and the fact that the existing vehicle-mounted voice control system cannot simultaneously recognize multiple action commands of the user and cannot recognize negative words in the user's voice command, the present invention proposes A car voice control method, system and device based on cloud and multi-command words. In the present invention, the collection of user voice commands is carried out through the vehicle-mounted terminal. After processing such as voice recognition, the vehicle-mounted terminal sends the generated text information to the cloud, and then obtains multiple command words in the user's voice through semantic analysis. At the same time, it can also Identify the negative words in the prefix and suffix of the command word and standardize the action range of the command word, and then the vehicle terminal executes t...

Abstract

The invention discloses an automobile voice control method, system and device based on a cloud end and a plurality of command words. The method comprises the following steps: carrying out voice recognition on a voice command to obtain a text message after voice recognition; through the cloud end, carrying out semantic analysis on the obtained text message, and carrying out matching to generate structured data comprising one or more command words according to a command word database stored in the cloud end; and executing a corresponding control command according to the generated structured data. The system comprises an interface module, a cloud end processing module and a vehicle-mounted master control module. The device comprises a storage device and a processor. The method can analyze theplurality of command words in the user voice command simultaneously, thereby improving execution efficiency; and since the user voice command is converted into the text message first, and then, the text message is subjected to semantic analysis, compared with a mode of carrying out matching treatment on the user voice command directly, the mode is high in matching accuracy and better in interaction. The method can be widely applied to the voice control field.

Description

technical field [0001] The invention relates to the field of voice control, in particular to a car voice control method, system and device based on cloud and multiple command words. Background technique [0002] With the continuous development of automobile information technology, the vehicle-mounted voice control system has also developed rapidly. It is of great significance to apply the voice control system to the control of electronic appliances inside the vehicle. The on-board voice control system can effectively reduce the driver's complex gestures and other inconvenient driving actions during driving, and through the driver's voice recognition can quickly, accurately and effectively realize the driving task functions required by the driver . The on-board voice control system provides a simple and effective way of interaction between the driver and the vehicle, enabling the driver to easily complete various controls and operations, improving driving safety and driving ...
