Abstract

A speech conversational system in a vehicle comprises a speech input unit, a speech conversion unit, a storage unit, an order identification unit, an application control unit and an application processing unit. The speech input unit is used for receiving a speech. The speech conversion unit is used for identifying the speech and converting the speech into phonetic feature information. The storage unit is used for storing scenario order texts corresponding to all vehicle-mounted application scenarios, and operational order texts corresponding to application operation under all the scenarios. The order identification unit is used for searching the scenario order text and the operational order text which are respectively matched with the phonetic feature information converted by the speech conversion unit from the storage unit, and forming a corresponding scenario starting order and a corresponding application operation order when searching out the matched scenario order text and the matched operational order text. The application control unit is used for analyzing the scenario starting order to start the corresponding application processing unit, and analyzing the application operation order to form application operation parameters which are supplied to the corresponding application processing unit. The application processing unit conducts the application operation corresponding to the application operation parameters after being started. The speech conversational system in the vehicle simplifies user operation and improves running safety of the vehicle.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to an in-vehicle voice dialogue system. Background technique [0002] Along with economic development and social progress, automobiles have gradually become popular consumer goods. The consumer group of automobiles is constantly expanding, and consumers have higher and higher requirements for automobiles. In recent years, in addition to economy and power, the driving experience during driving has also become the focus of consumers. The technical development of vehicle equipment is also getting deeper and deeper. [0003] At present, most cars are equipped with in-vehicle devices with functions such as playing music, listening to radio, reading e-books, and the like. These in-vehicle devices provide users with a variety of entertainment and application experience during driving. With the development of liquid crystal touch technology, the control panel of vehicle e...
