A kind of secure voice communication device of portable terminal device
Technical field
The utility model relates to a kind of electronic device field of portable terminal device, relates in particular to a kind of secure voice communication device of portable terminal device.The utility model is used through voice data collection, voiceprint analysis and data, and coming provides functions such as incoming person's identity validation, identification for the user, makes the user in the voice call process of portable terminal device, security arranged more.
Background technology
Portable terminal device uses in a large number at present; The mode that the lawless person utilizes portable terminal device to swindle is to emerge in an endless stream, and swindles the increasing of propaganda strength along with government is counter, and the common people take precautions against for most swindle to some extent; But when everybody receives the phone of being familiar with number; Always can lose vigilance, the incoming person is not people's (perhaps your acquaintance loses portable terminal device) that you are familiar with in fact, thereby has caused unnecessary loss; So we need a kind of portable terminal device that has the Application on Voiceprint Recognition function, guarantee that our voice call is more safe.
Compare with other recognition technology (like fingerprint recognition, palmmprint identification, iris recognition etc.); Vocal print does not have advantages such as can losing or forget, need not remember, be easy to use, therefore protection people's property, avoid theft or other economic crimes aspect having bigger purposes.The user is also high to the acceptance level of Application on Voiceprint Recognition technology, because do not relate to privacy concern, the user does not have any mental handicape.Utilizing vocal print to carry out identification possibly be one of natural and the most most economical method, is highly suitable for and uses this technology on the portable terminal device.
Summary of the invention
In order to solve the insecurity of voice call on the present portable terminal device, the purpose of the utility model has been to provide a kind of secure voice communication device of portable terminal device.
The technical scheme that the utility model is taked is following.
A kind of secure voice communication device of portable terminal device comprises: vocal print storehouse, voice call recording module, live recording module, other voice acquisition module, vocal print data module, and described vocal print storehouse connects the vocal print data module; Voice call recording module, live recording module, other voice acquisition module sample sounds are transferred to the vocal print data module.
The vocal print storehouse is set up, and at first is the sample sound collection, and this can have multiple mode, when the user links up with the other side at ordinary times, can gather the other side's sample sound with portable terminal device, is stored in the portable terminal device; Also can with the other side's telephone relation process in, gather variety of ways such as vocal print sample.Then the sample sound that collects is carried out voiceprint analysis, set up corresponding vocal print storehouse.Next be the application in the voice call process, on-the-spot sound collection, in the process of voice call, enough acoustic informations can be gathered by system, so that can reach and the requirement relatively of vocal print storehouse.The vocal print data analysis, utilize collection in worksite to acoustic information and vocal print storehouse analyze.Result's feedback after the Application on Voiceprint Recognition systematic analysis, is in time pointed out the user through modes such as demonstration on the UI and vibrations.The user Application on Voiceprint Recognition system of can conversing safer carries out speech communication.

The practical implementation method
Below in conjunction with accompanying drawing and instance the utility model is further specified.
As shown in Figure 1, described vocal print storehouse 1 connects vocal print data module 4; Voice call recording module 2, live recording module 3, other voice acquisition module 4 are gathered sample sound and are transferred to vocal print data module 5.The first step in the function of bringing into play the Application on Voiceprint Recognition system; Need to gather the vocal print sample, the user can gather the vocal print sample in several ways, and sample has the requirement of aspects such as quality and time span certainly; The most frequently used is in the process of voice call, carries out the collection of vocal print sample; Be exactly that modes such as live recording are gathered the vocal print sample in addition.The process of exactly the vocal print sample that collects being analyzed then, processing such as filtering noise generate corresponding storehouse to the vocal print sample, bind corresponding address list.
After the vocal print storehouse formed, the Application on Voiceprint Recognition system just can utilize this storehouse to carry out various application, as when voice call begins; The system searching address list confirms whether to exist corresponding voiceprint, under situation about existing; Begin to carry out on-the-spot sound collection; After collecting suitable sound, carry out voiceprint analysis, whether confirm with the vocal print storehouse in the corresponding information coupling.The result who analyzes goes up modes such as prompting, sound, vibrations and feeds back to the user through UI, the user makes the response of oneself again.
