Problems solved by technology

The shortcoming of one of prior art: 1) can be used for speech recognition in the unrestricted scope, and its cost is relatively high
2) The recognition speed of ASR technology is relatively slow. For intelligent voice services, it is generally necessary to recognize the voice within a limited time and perform subsequent dialing and other processing.
Two shortcoming of prior art: 1) this scheme is very high to the requirement of speech quality, when speech quality has certain distortion, the correct rate of speech recognition just has obvious decline
2) According to this scheme, to recognize a voice, it is necessary to extract the voice feature quantity between the start and end points of the voice, that is, to recognize the voice at least until the voice is played to the end point, the efficiency is not high enough

Embodiment approach

[0033] The voice recognition method of the present invention realizes efficient and accurate recognition of voices within a limited range (that is, voices to be recognized are a certain number of voices, not arbitrary voices) through a simple and practical method. combine figure 1 A basic application networking diagram of the shown next generation network (Next Generation Network, hereinafter referred to as NGN), describes an embodiment of the present invention, wherein: SoftSwitch (soft switch) is the intelligence and switching center of the NGN whole network, It controls each access media gateway (Access Gateway, hereinafter referred to as AG) through a media gateway control protocol (such as H.248); Resource Server, hereinafter referred to as MRS) is used to provide users with various media resources. For example, some voice prompts heard by users during use (such as "the line is busy, please dial later") are played by MRS and passed through VoIP (Voiceover IP) sent to the...

Abstract

This invention relates to a method for identifying phones with limited spheres automatically including: A1, setting up the corresponding relation between the phone files and label information in a limited set, plugging the label information in the phone files or replacing the phone information in the file with the label information to be sent by the transmitting end, A2, the receiving end receives the modified phone files, picks up effective label information and searches the corresponding phone information based on the effective label information.

Description

technical field [0001] The invention relates to a method for automatically recognizing voices within a limited range, in particular to a method for automatically recognizing voices within a limited range in a telephone intelligent voice system. Background technique [0002] When testing PSTN (Public Switched Telephone Network) switches, softswitches, access gateways and other related products, it is necessary to test some services that require intelligent voice. For example, when dialing a wrong number by phone, you will hear " Your number is wrong, please check and dial again." After registering a new supplementary service, you will hear voice prompts such as "The new service you applied for has been registered, welcome to use" and so on. For most cards Similar businesses and businesses on duty with computers also use voice prompts extensively to prompt users or guide users in their follow-up operations. During manual testing, these voices are listened to and judged by hum...
