Problems solved by technology

[0003] However, the current in-vehicle voice system is to use the cloud voice recognition method for voice recognition first. If the cloud voice recognition does not return a result within a certain period of time, the voice to be recognized will be sent to the terminal voice recognition module, which means that the terminal voice recognition module needs to Keep it on all the time, even in the sleep state, it needs to occupy the car resources all the time, which greatly wastes CPU and memory

Embodiment 1

[0045] figure 1 It is a flow chart of a vehicle-mounted voice recognition method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the vehicle-mounted voice recognition system recognizes the voice information input by the user. This method can be implemented by the vehicle-mounted voice recognition device in the embodiment of the present invention. To execute, the device can be implemented in software and / or hardware, such as figure 1 As shown, the method specifically includes the following steps:

[0046]S110, if the cloud successfully receives the voice information input by the user, perform voice recognition on the voice information, and if the recognition fails or the recognition times out, send an enabling instruction to the terminal, so that the terminal receives the voice information input by the user, and Voice recognition is performed on the voice information.

[0047] Specifically, before inputting the voice inf...

Embodiment 2

[0053] figure 2 It is a flowchart of a vehicle-mounted speech recognition method in Embodiment 2 of the present invention. This embodiment is optimized based on the above-mentioned embodiments. In this embodiment, if the cloud successfully receives the voice information input by the user, then Carry out voice recognition on the voice information, if the recognition fails or the recognition times out, then send an open instruction to the terminal, so that the terminal receives the voice information input by the user, and before performing voice recognition on the voice information, it also includes: cloud Periodically send status information to the terminal; if the cloud is in an abnormal state, then send the abnormal status information to the terminal, so that the terminal starts the speech recognition function after receiving the abnormal status information.

[0054] Such as figure 2 As shown, the method of this embodiment specifically includes the following steps:

Abstract

The invention discloses a vehicle-mounted voice recognition method, device and equipment and a storage medium. The method comprises the steps that if a cloud successfully receives voice information input by a user, voice recognition is conducted on the voice information, and if recognition fails or recognition is overtime, a starting instruction is sent to a terminal, so that the terminal receivesthe voice information input by the user, and voice recognition is conducted on the voice information; and if the cloud fails to receive the voice information input by the user, an opening instructionis sent to the terminal, so that the terminal receives the voice information input by the user and performs voice recognition on the voice information. Through the technical scheme of the invention,the voice recognition module can always have only one service in an enabled state, so that the resource occupancy rate of the terminal voice recognition module in the voice system is effectively reduced, and the operation speed of the voice system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular, to a method, device, device and storage medium for vehicle speech recognition. Background technique [0002] With the rise of the field of artificial intelligence, the application of intelligent voice in cars is becoming more and more extensive. At present, voice control in cars has become a basic function of cars. Speech recognition converts speech into corresponding text information, and has become one of the most important modules in speech, and it is also one of the modules that occupy the most resources. At present, there are two ways to implement speech recognition, one is network-based cloud speech recognition, and the other is car-based terminal speech recognition. Cloud speech recognition takes up almost no terminal resources, but it cannot be used when the network is not connected or the network signal is poor. Therefore, at present, most vehi...
