Embodiment Construction

[0026] Embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0027] figure 1 A block diagram of an embedded voice network search device according to an embodiment of the present invention is shown. Each component in the dotted box is a basic functional block embedded in the mobile communication terminal, and these basic functional blocks form a Voice Web Search (VWS) engine. Usually, the VWS engine receives the user's voice, converts the voice into query text, and starts an Internet search through 3G, WIFI, WAP or GPRS protocols.

[0028] VWS engine includes user interface unit, speech recognition engine, acoustic model (AM), language model (LM), network search unit, content analysis unit, context extraction unit, intelligent display ...

Abstract

The invention provides a voice network search method and device for a mobile communication terminal. The voice network search method includes the following steps: when the user starts the voice network search function, receiving the voice signal input by the user; recognizing the voice signal input by the user on the acoustic level indicated by the pronunciation symbols based on the acoustic model, and recognizing the voice signal based on the language model transcribe speech signals into text data; initiate Internet searches based on recognized text data; record and store search results; display search results; collect various raw text data and normalize raw text data; use and analyze speech signals to tune the acoustic model, and the regularized text data to tune the language model.

Description

technical field [0001] The present invention relates to voice network search technology, more specifically, relates to a voice network search method and device for mobile communication terminals with adaptive acoustic model and language model. Background technique [0002] Internet access and searching on mobile platforms has become very popular in recent years. For the Chinese network search user, it is first necessary to key in the character to be searched in the search window or to write this character on the display screen. Then, a web search is started based on the query keyword, and the obtained search results are displayed on the display screen. [0003] With the development of speech recognition technology, methods for network recognition using speech input have been proposed. However, although the voice network search method can greatly facilitate users, there are still serious deficiencies. [0004] For example, existing speech recognition technology has low rec...
