Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is introduced in further detail:

As shown in Figure 1, the portable terminal of the utility model embodiment one comprises:

Transmitter 10, audio frequency multimedia digital codec 20, individual speech recognition device 30 and processor 40;

Wherein, transmitter 10 is used for receiving speech information;

Audio frequency multimedia digital codec 20 links to each other with transmitter 10, is used for described voice messaging is converted to digital signal;

Individual's speech recognition device 30 links to each other with audio frequency multimedia digital codec 20, is used for described digital signal is carried out person identification and speech recognition;

Further, described individual speech recognition device 30 can comprise:

Memory module 301, storage is used to discern the speech characteristic parameter of personal identification;

Identification module 302 carries out person identification according to described speech characteristic parameter;

Sound identification module 303 after identification module 302 carries out person identification, resolves to described digital signal the control command of operating mobile terminal application function;

Processor 40 links to each other with individual speech recognition device 30, calls mobile terminal application function such as voice call, transmitting-receiving note, multimedia recreation, system's setting, gets online without being tethered to a cable or the like according to described control command;

Memory module 301 has been stored the speech characteristic parameter that is used to discern personal identification in advance, pass through some statements of transmitter 10 typings in advance by the specific user in realization, after converting digital signal to, audio frequency multimedia digital codec 20 extracts the language feature parameter such as the speech frequency of identification personal identification by identification module 302, loudness, be stored to memory module 301 after the situation of frequency change etc., when the user answers by voice control incoming call, identification module 302 carries out identification to voice messaging earlier, identification is carried out speech recognition again by back sound identification module 303, resolves to the control corresponding instruction and does the various application functions that follow-up operation comes the voice operating portable terminal by processor 40.

As shown in Figure 2, what suppose in the mobile terminal stores module 301 storage is the speech characteristic parameter of user A, answer with the incoming call of voice control portable terminal and to be example, after portable terminal is received incoming call, user A assigns " incoming call answering ", phonetic order such as " hang up incoming call ", transmitter 10 receives the voice messaging of user A, be transferred to audio frequency multimedia digital codec 20 and be converted to digital signal, identification module 302 carries out identification according to the speech characteristic parameter of storage in the memory module 301 to digital signal, determine again digital signal to be carried out speech recognition after the user A identity, with the user's voice information Recognition is " incoming call answering ", control command such as " hang up incoming call ", and control command is flowed to processor 40 operate accordingly and realize that voice control incoming call answers.

If another user B assigns phonetic order and controls the incoming call of this portable terminal and answer, obviously identification module 302 can't be discerned the identity of user B, then can't carry out follow-up speech recognition, portable terminal can not made a response to the phonetic order of user B, continue to wait for the user input voice instruction, assign corresponding phonetic order and operate accordingly until user A.

When user A and other users assign phonetic order to portable terminal simultaneously, individual speech recognition device 30 only can identify the identity of user A, and then portable terminal is only made a response to the phonetic order of user A.

Portable terminal is that direct phonetic order to user A carries out identification in the above-described embodiments, when user A answers by voice control incoming call in realization, also can adopt the voice messaging of " special sentence+phonetic order ", the identity of user A is judged in the special sentence special use, identification resolves to phonetic order corresponding control command again by the back portable terminal, special sentence can be " I am user A " or the like, the user can assign such as " I am user A; connecting incoming call " such voice messaging and come connecting incoming call like this, obviously such voice messaging can't connecting incoming call by assigning " I am user A, connecting incoming call " for user B.

Obviously, according to the introduction of the foregoing description, when portable terminal was received new message, user A also can also can finish foundation with similar mode, send new message by controlling the reception new message such as the statement of " opening new message " or " I am user A; open new message ".

In like manner, user A can adopt also that the mode in similar the foregoing description is come other application functions such as phonetic dialing, the music of voice operating portable terminal, taken pictures, function setting etc., repeats no more herein.
