Voice broadcast method and device applied to car networking

Abstract

The invention provides a voice broadcast method and a voice broadcast device applied to car networking. The method comprises the following steps: receiving a voice broadcast instruction; according tothe broadcast content in the instruction, judging that whether the broadcast content exists in the local cache or not; if the broadcast content exists in the local cache, directly broadcasting the corresponding content in the cache; if the broadcast content does not exist in the cache, further judging that whether the car networking use scene is the fixed feedback type scene, the specific local scene or the cloud scene; and according to the different car networking use scenes, carrying out broadcasting by using the different voice synthesis modes correspondingly, and caching the correspondingbroadcasting data. With the method and the device, the problem that in the prior art, broadcasting with the different voice synthesis modes under the different scenes in combination with the car networking use scenes can not be realized is solved, meanwhile, the voice naturalness is promoted, and the power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, in particular to a method and device for voice broadcasting applied to the Internet of Vehicles. Background technique [0002] At present, in the field of Internet of Vehicles technology, there are mainly offline synthesis methods and online synthesis methods for broadcast voice synthesis technologies. The main advantage of the offline speech synthesis method is that it does not require network support, and the speech to be broadcast can be synthesized directly on the device side; the main disadvantages are: 1) the supported group of words is limited in pronunciation; 2) it relies on local annotations and terminal calculators / storage resources Capacity limitation; 3) The algorithm model is built based on a single bit rate, and the sound quality is difficult to guarantee; 4) The algorithm needs to consume more resources on the device side, and voice broadcast may freeze. The main...
