Refer to Fig. 1, the flow chart of the method for switching languages preferred embodiment that Fig. 1 is TV channel provided by the invention, as shown in the figure, the method for switching languages of described TV channel comprises the following steps:
Step S100, reception user's voice messaging, is recorded as corresponding voice signal;
Step S200, described voice signal is sent to voice high in the clouds, by voice high in the clouds, carries out speech recognition, and the recognition result of speech recognition is returned to television set;
Step S300, according to described recognition result, mate, search the channel key encoded radio that described recognition result is corresponding, and control television set and switch to corresponding channel;
Step S400, record the television audio signals of the scheduled time length of described channel;
Step S500, extract the vocal print signal of described television audio signals;
Step S600, described vocal print signal is sent to the real-time voice bank of TV station, by the real-time voice bank of TV station, carries out Application on Voiceprint Recognition coupling, and the channel text message corresponding to matching result of Application on Voiceprint Recognition coupling returned to television set;
Step S700, the channel channel corresponding with matching result corresponding to described recognition result compared, whether consistent according to the channel that channel corresponding to described recognition result is corresponding with matching result, determine whether upgrading TV channel text list.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
In step S100, receive user's voice messaging, be recorded as corresponding voice signal.Specifically, can by the MIC of television set, receive user's voice messaging, the voice command that has comprised switching channels in user's voice messaging, for example switches to certain so-and-so channel, regulates the orders such as volume and briliancy.In general, microphone can be arranged on television set, but when practical application, for fear of people from television set away from, the MIC identification that causes arranging on television set is inaccurate, microphone can be arranged on remote controller.Preferably, when the acoustic control press key of pressing on remote controller, television set enters acoustic control automatically switching channels function, receives user's voice command by the microphone on remote controller.That is to say after pressing acoustic control press key, by the microphone on remote controller, receive the phonetic order signal of recording user, then send voice signal to television set.
In step S200, described voice signal is sent to voice high in the clouds, by voice high in the clouds, carry out speech recognition, and the recognition result of speech recognition is returned to television set.Specifically, television set receives the voice signal that remote controller sends, and it is uploaded to voice high in the clouds by network identifies speech recognition, and the channel text message recognizing is back to television set by network.Described voice high in the clouds is voice cloud platform, and the user's that can upload television set voice signal carries out speech recognition, then the voice TEXT content of text of identification is passed back to television set by network.For example, the voice command signal in user's voice messaging is identified, and form corresponding text message and feed back to television set, for example, volume is adjusted to 50, switches to ' Shenzhen amusement ' television channel etc., do not do too much description herein.
In step S300, according to described recognition result, mate, search the channel key encoded radio that described recognition result is corresponding, and control television set and switch to corresponding channel.Specifically, television set, after receiving the recognition result that speech recognition high in the clouds issues, mates according to the content of text of the recognition result of voice cloud identification, searches its corresponding channel key encoded radio, then Set Top Box is controlled, carried out corresponding channel switching.That is to say, television set is after receiving speech recognition text message out, according to the TV channel text list arranging, in described TV channel text list, different channel key encoded radio corresponding to TV channel text message, it is tabled look-up and searches corresponding channel key code value, then send code value controller top box and be switched to corresponding channel, thereby complete voice automatic channel switching controls.Described recognition result is corresponding channel text message, and for example channel text message is " CCTV1 ", and searching TV channel text list, can to obtain corresponding code value be 1.Then can control television set by a plurality of modes and switch to channel corresponding to button No. 1, for example pass through Set Top Box.
In order to verify the correctness of voice automatically switching channels, the present invention further comprises following steps.In step S400, record the television audio signals of the scheduled time length of described channel.Specifically, after voice automatic channel has switched, television set obtains the television audio signals of the TV programme that one section of active user watching, and that is to say, after acoustic control channel has switched, television set can automatic recording a period of time length be the television audio signals of T.
In step S500, extract the vocal print signal of described television audio signals.Specifically, the audio signal of recording is processed, extracted vocal print signal, by predefined algorithm, extract corresponding vocal print characteristic signal exactly.
