Vehicle mounted terminal oriented man-machine interaction system based on speech recognition

Abstract

The invention provides a vehicle mounted terminal oriented man-machine interaction system based on speech recognition which relates to the safe driving technology field. A speech input module is connected with a speech recognition module; the speech recognition module is connected with an adapter module; the adapter module is connected with a speech feedback module; the speech feedback module is connected with the vehicle mounted terminal; the speech input module is used to obtain audio information from the external which includes effective speech instructions and invalid audio information; the speech recognition module is used to decode the audio signal and transforms it into text information that can be read by the system to recognize speech through a server or the speech engine at a local end; the adapter module is used to extract the contents in the text information and transforms them into commands and decodes the commands related to the application function at the speech terminal and the unrelated non-commands; the speech feedback module is used to provide different interaction feedback to the outputted result of the adapter module; according to the invention, a more natural and people-oriented man-machine interaction mode is provided for a vehicle mounted terminal regardless of a network or not.

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a vehicle-mounted terminal human-computer interaction system with a voice recognition function. Background technique [0002] With the rapid development of China's automobile industry and the increasing number of automobiles, automobile consumers have put forward higher requirements for automobile performance. The trend of intelligence, networking, and electronics has become the theme of the current automobile industry.
