Embodiment Construction

[0014] The present invention will further introduce the embodiments of the present invention in conjunction with the accompanying drawings.

[0015] 1. The navigation system voice prompts the user to use the microphone for voice input, so that it is easy to distinguish between effective input voice and external environmental sound.

[0016] 2. Read in the external input voice, and use the adaptive filter designed with the minimum mean square error as the criterion to filter and remove the environmental noise.

[0017] 3. The adaptive speech recognition method is realized as follows:

[0018] (1) According to the characteristics of the navigation system, a related vocabulary database is established. The database includes the control command vocabulary of the navigation system and the fuzzy related vocabulary of the control command vocabulary. The fuzzy related vocabulary stores the vocabulary that controls the navigation execution. Synonyms and vocabulary with similar pronunci...

Abstract

A voice interaction control guide system and a method of the voice interaction control guide system are a guide function using a voice interaction way to achieve the guide system. A current guide system generally adopts a mouse, a keyboard, a touch interaction of combination of an image and a written language and the like as an interaction way. The above interaction way can not satisfy the needs of different levels of people and different groups of people, such as the blind and children who are illiterate. The voice interaction control guide system carries out corresponding guide functions according to a voice command. A self-adaption voice recognition method and a heuristic prompt method are adopted by the voice interaction control guide system. The voice interaction control guide system stores related words commonly used for guiding in a background database according to property of the guide system, and therefore the system can search in a corresponding database when a user sends a voice command, and matching speed is improved. If corresponding matching words and sentences are not searched, the system responds and asks whether corresponding operation is needed to be done by the adoption of voice, and then the user just answers 'yes' or 'no', the system enters the next guide, and a humanized guide function is achieved.

Description

technical field [0001] The invention relates to the fields of speech recognition, speech interaction, navigation technology, digital media and the like. Disclosed is an implementation method based on voice interactive control navigation, adopts Microsoft voice recognition engine, and adopts the method of adaptive filter filtering and adaptive recognition based on the minimum mean square error to improve voice recognition rate and real-time performance. Background technique [0002] With the continuous maturity and popularization of digital media and network technology, the application of digital navigation system is more extensive, such as the display of smart city experience hall, the virtual display of smart home, the display of scenic spots in smart tourism, the guidance system of public buildings, etc. , all with navigation capabilities. [0003] At present, the interaction methods of most navigation systems generally use mouse, keyboard interaction, touch interaction c...
