Background
The speaker verification technology is a technology for performing feature matching with a sampled voice sample by analyzing voice features of a speaker and performing identity verification according to a matching result. The technique verifies the person speaking by analyzing a unique characteristic of the speech sample, such as the frequency of the utterance. Speaker verification techniques allow a person to control access to restricted areas by speaking voice, accessing identity sensitive data such as: telephone banking, database services, voice mail, etc. The voice sample, called voiceprint, is a sample of voice that is used as a validation criteria, typically a directly recorded user voice.
The speech verification (speech hsc) working group in the current Internet Engineering Task Force (IETF) defines the application network architecture of Speaker verification (Speaker identifier/Speaker Verified, SI/SV). The IETF mentions the Application scenario and proposed architecture of the technology in RFC4313, AS shown in fig. 1, wherein an Application Server (AS) is proposed to control services, a media processing unit is adopted at a lower layer to support media processing functions and media interaction with a client, a speaker verification command from the Application Server is received through an additional SI/SV Server, and a voice sent by a media resource processing entity is received to perform speaker verification, and then a verification result is reported to the AS. Wherein, the SI/SV server performs control signaling interaction related to speaker verification/authentication with AS and media processing unit through a specially defined SPECECHSC protocol.
In a system with separated media control and bearer, a media resource control entity and a media resource processing entity generally interact with an AS to implement a media resource service. If the speaker verification technology needs to be implemented in a system with separation of media control and bearer, according to the network architecture of speaker verification, the SI/SV server needs to be installed in the system with separation of media control and bearer, and the existing protocol structure needs to be changed, which greatly changes the existing network and also causes high cost of network upgrade.

The media resource control entity in this embodiment may be an MGC, and the corresponding media resource processing entity is an MG; the media resource control entity may also be MRFC, and the corresponding media resource processing entity is MRFP.
The following describes a network architecture based on this embodiment by way of an example. AS shown in fig. 4, for a network architecture applied to an IP Multimedia Subsystem (IMS) network in this embodiment, the network architecture includes an AS, an S-CSCF, an MRFC, and an MRFP, where the MRFC receives a speaker verification command from the AS through the S-CSCF, instructs the MRFP to obtain a corresponding voiceprint and a user voice input according to the command, performs verification, and returns verification result information to the S-CSCF. Of course, other entities may be included in the IMS network, but are not shown here since they are not germane to embodiments of the present invention.
The general flow of the specific embodiment of the method for realizing speaker verification provided by the invention is shown in fig. 5, and mainly comprises the following steps:
The media resource control entity and the media resource processing entity may be MGC and MG, or MRFC and MRFP. The following describes the present embodiment in detail by taking an example that the present embodiment is applied to an IMS network architecture, that is, the media resource control entity and the media resource processing entity are MRFC and MRFP. As shown in fig. 6, when the present embodiment is applied to an IMS network architecture, the method specifically includes the following steps:
step 601, after the bearing channel between the MRFC and the MRFP is established, the MRFC receives a speaker verification command from the S-CSCF, and the command comprises voiceprint information of a speaker. The voiceprint information here is the path and name of the voiceprint corresponding to the user. The speaker verification command sent by the S-CSCF to the MRFC is usually from the AS, and in addition, the AS may send the speaker verification command directly to the MRFC.
The MRFC may specifically include a speaker verification and service information interaction module, a control module, and a media control interaction module. The method specifically comprises the following steps: the speaker verification and service information interaction module receives service information from the AS directly or through the S-CSCF, namely a speaker verification command comprising speaker voice ripple information, and transmits the speaker verification command to the control module.
Step 602, the MRFC converts the received speaker verification command into a speaker verification request, and converts the request into an h.248 message format to be sent to the MRFP through the Mp interface between the MRFP and the MRFP.
Specifically, in this step, the control module in the MRFC may generate a speaker verification request according to the received speaker verification command, and transmit the verification request to the media control interaction module, and the media control interaction module converts the verification request into a format supported by the h.248 protocol and transmits the format to the MRFP.
The speaker verification request in this step may adopt a mod.req message in the h.248 protocol, which includes information of the service session endpoint T1, and the value of the signal is speaker verification. In addition, the request may specifically include one or more of the following information:
1) a voiceprint identification; the voiceprint information comprises a path and a name of the voiceprint, wherein the path stored by the voiceprint can be a local server path or a network server path; the voiceprint name adopts a character string, but the voiceprint name is required to have uniqueness under a specified path;
2) a score threshold; the value range is 0-100, and the MRFP is used for confirming whether the speaker verification is successful according to the threshold, and when the matching result score is greater than or equal to the value, the verification is considered to be successful;
3) an initial prompt tone; when the prompt tone played before user authentication is started, the user performs voice input according to the prompt tone;
4) verifying a successful prompt tone; when the matching result score is greater than or equal to the score threshold value, a success prompt tone is played;
5) a verification failure prompt tone; when the matching result score is smaller than the score threshold value, playing a failure prompt tone;
6) maximum number of no input allowed prompts; when the voice of the user is not received, prompting the user to carry out the maximum number of times of voice input through the initial prompt tone;
7) waiting for the maximum time length of a timer for the voice input of a speaker; the parameter is used for indicating the maximum time for waiting for voice input, and if the time is out, processing is carried out according to verification failure;
8) a voice input end detection key; the user can end the voice input by pressing a key, and can be informed of the specific key by an initial prompt tone.
The speaker verification request includes information generated based on corresponding information preset in the MRFC, except that the voiceprint identifier is from the speaker verification command.
Step 603, after receiving the speaker verification request, MRFP returns mod.resp message including the information of the endpoint T1 to MRFC.
The MRFP may specifically include a media control interaction module, a control module, a speaker verification processing engine, a voiceprint acquisition module, and a speaker voice reception module. In this step, the media control interaction module in the MRFP receives the speaker verification request in the h.248 protocol format, converts the request into information that can be identified by the control module in the MRFP, and transmits the information to the control module; and the control module of the MRFP generates a Mod.resp message as a response according to the received request and sends the Mod.resp message to the MRFC through the media control interaction module of the MRFP.
Step 604, the MRFP performs verification processing, specifically including obtaining a corresponding voiceprint according to a voiceprint path and a voiceprint name in a voiceprint identifier in the speaker verification request, and if a voiceprint is not obtained, returning verification failure information or returning error information to the MRFC through a not. If the voiceprint is obtained, an initial prompt tone is played to the user and the user input is waited for, after the user voice input is received, the MRFP compares the voice input by the user with the obtained voiceprint sample to obtain a verification result score, if the verification result score is more than or equal to a score threshold value, a verification success prompt tone is sent to the user, and in step 605, information of successful verification is returned to the MRFC through not. If the verification result score is less than the score threshold, a verification failure prompt tone is sent to the user, and information of verification failure is returned to the MRFC through a not.
In the step, the control module informs the voiceprint acquisition module to acquire the corresponding voiceprint according to the speaker verification request from the media control interaction module, transmits the acquired voiceprint to the speaker verification processing engine, and controls the speaker voice receiving module to play an initial prompt voice to the user and receive voice input from the user; if the speaker voice receiving module receives the voice input of the user before the maximum time length of the timer waiting for the voice input of the speaker, the voice input is transmitted to the speaker verification processing engine after receiving the voice input end detection key or the preset input time length; if the voice input of the user is not received after the maximum time length of the timer waiting for the voice input of the speaker is reached, informing a speaker verification processing engine to determine that the verification fails; the control module also controls the speaker verification processing engine to perform speaker verification according to the voiceprint received by the speaker verification processing engine and the user voice input, the speaker verification processing engine compares the obtained voiceprint with the received user voice input according to the acoustic characteristics so as to generate a matching result score, the score is compared with a score threshold value in a speaker verification request, if the matching result score is greater than or equal to the score threshold value, verification success is determined, and a prompt tone for successful verification is played to the user through the speaker voice receiving module; otherwise, determining that the verification fails, and playing a prompt tone for the user through the speaker voice receiving module; the speaker verification processing engine sends the verification result of successful verification or failed verification, or other further included information, such as matching result score, duration of voice input by the user, voiceprint identification and other verification result information to the control module, and the control module transmits the information to the media control interaction module. If all the modules involved in the step are modules in the MRFP.
Step 605, the MRFP returns the verification result information to the MRFC, and specifically, the verification result information may be carried by the not. The verification result information at least includes information on whether the verification is successful, and may further include one or more of the following information:
1) the matching value, namely the matching result score, can be 0-100, wherein 100 matches are the best and 0 matches are the worst;
2) inputting the duration of the voice;
3) and (4) carrying out voiceprint identification.
And the media control interaction module in the MRFP converts the received verification result information into a format supported by the H.248 protocol and sends the format to the MRFC.
Step 606, after receiving the verification result information, the MRFC returns a not.
The step specifically includes that a media control interaction module in the MRFC receives the verification result information from the MRFP, performs protocol conversion processing to obtain information that can be identified by a control module in the MRFC, and sends the information to the control module, and after receiving the information, the control module returns a not.resp message in an h.248 protocol format to the MRFP through the media control interaction module to respond.
Step 607, MRFC converts the received verification result information into a message supported by the Mr interface between itself and S-CSCF, and sends it to S-CSCF, which then sends the verification result information to AS. Of course, the MRFC may send the authentication result information directly to the AS without passing through the S-CSCF.
The control module in MRFC transfers the received verification result information from the media control interaction module to the speaker verification and service information interaction module, and the speaker verification and service information interaction module returns the verification result information to AS directly or through S-CSCF according to the verification result information.
It can be seen from the above-mentioned solutions described in the embodiments that, in the present invention, the media resource control entity instructs the media resource processing entity to perform speaker verification processing, and the media resource processing entity receives and verifies the voice input of the speaker according to the instruction of the media resource control entity, and reports the verification result to the media resource control entity, without changing the existing network architecture and protocol structure with separated bearer control, the speaker verification technology is implemented, and the cost of network upgrade is reduced.
In addition, the invention realizes that the media resource control entity in the existing network architecture can support speaker verification processing by providing the media resource control entity comprising the speaker verification and service information interaction module, the control module and the media control interaction module.
And by providing a media resource processing entity comprising a media control interaction module and a speaker verification module, the media resource processing entity in the existing network architecture can support speaker verification processing.
The foregoing is a description of specific embodiments of the invention, and the method of the invention may be modified, as appropriate, during the course of particular implementations to suit the particular needs of particular situations.
