Embodiment Construction

[0039] figure 1 It is a network architecture for processing media resource services in a WCDMA IMS network. Among them, the application server 1 is used to process various services, such as playing announcements to users, collecting numbers, conferences, and recordings. The service call session control device 2 is used for routing, and correctly forwards the message sent by the application server to the media resource control device 3 , or correctly routes the message sent by the media resource control device 3 to the application server 1 . The media resource control device 3 is used to control the media resources, and according to the requirements of the application server 1, selects the corresponding media resource processing device 4 and controls the processing of the media resources. The media resource processing device 4 is used for media resource processing, and completes the media resource operation processing issued by the application server 1 under the control of the...

Abstract

A method, apparatus and system can accomplish the function of speech recognition; a media resource control device controls a media resource-processing device by H.248 protocol to accomplish the recognition of speech, which was input by the user. The method comprises: the media resource processing device receiving the H.248 message with speech recognition indications and correlation parameters from the media resource control device; and the speech recognition can be processed based on the indications and parameters; and the result of recognition can be sent to the media resource control device. Otherwise, the apparatus and the system, which can accomplish the function of speech recognition, can be provided.

Description

technical field [0001] The invention relates to a method for realizing the speech recognition function, in particular to a method for realizing the speech recognition function using the H.248 protocol as a control protocol. Background technique [0002] The speech recognition function refers to the recognition of the speech input by the user according to the specified grammar, and converts it into text. For example, in an interactive application, the system first plays a prompt to the user: "Do you need water, cola, or juice?". The user can answer by voice. The user's pronunciation can only be the voice including the keywords "water, cola, juice, no need". The system can recognize the user's voice and then provide the user with the selected products. [0003] In fixed or mobile network applications, when user input is required, there are generally two methods: [0004] One method is that the user inputs a DTMF (Dual Tone Multi-Frequency, Dual Tone Multi-Frequency) tone. F...
