Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation of the embodiment of a kind of intelligent voice control set-top box remote controller of the utility model.As shown in Figure 1, present embodiment intelligent voice control set-top box remote controller 1 comprises miaow head 11, sound identification module 12, MCU 13 and infrared transmitting tube 14, wherein:
Miaow head 11, being used for the user's voice command conversion is the signal of telecommunication;
Sound identification module 12 be used for to receive the described signal of telecommunication, with the described signal of telecommunication by spectral conversion obtaining phonetic feature, and the phonetic feature that obtains and default keyword mated, thus with the Optimum Matching keyword that obtains as recognition result;
MCU13 is used for receiving described recognition result, and according to the keyword of MCU register memory storage the corresponding relation of infrared coding is tabulated, and described recognition result is converted to corresponding infrared encoded signal;
Infrared transmitting tube 14 is used for receiving described infrared encoded signal and exporting to set-top box.
Concrete, please in conjunction with Fig. 2, below sound identification module 12 is described in further detail.As shown in Figure 2, the sound identification module 12 of the utility model embodiment comprises spectral conversion unit 121, feature extraction unit 122, voice match unit 123 and lists of keywords 124, wherein:
Lists of keywords 124 stores default keyword, and described default keyword is corresponding one by one to the keyword in the corresponding relation tabulation of infrared coding with the keyword of described MCU register memory storage.
Understandable, the described sound identification module 12 in the present embodiment can adopt the LD3320 voice recognition chip.
Need to prove, the described intelligent voice control set-top box remote controller of present embodiment, when latest keywords being deposited in described MCU register when upgrading described keyword to the tabulation of the corresponding relation of infrared coding, described MCU13 deposits described latest keywords the lists of keywords of described sound identification module in, to upgrade described lists of keywords.
Be understandable that, in an embodiment, each each channel designation in the corresponding channel list can be deposited in the described MCU register as keyword, and the corresponding infrared coding of each keyword, thereby set described keyword to the corresponding relation tabulation of infrared coding.
Be understandable that, when using the intelligent voice control set-top box remote controller of present embodiment, remote controller is to use battery or other supply power mode work, in order to allow the functional modules such as sound identification module 12 can be not in running order always, can be on remote controller a certain specific position the audio-switch button 15 of a special use is set, described audio-switch button is electrically connected with described MCU, the user makes described MCU13 produce to interrupt when pressing described audio-switch button, and then start described sound identification module 12 and described miaow head 11, make the described miaow head 11 can the order of typing user's voice.
Below, in conjunction with Fig. 1 and Fig. 2, the concrete workflow of the intelligent voice control set-top box remote controller 1 of present embodiment is described:
At first, described MCU13 is produced to interrupt, this moment, the light-emitting diode (not shown) flicker on the remote controller also started sound identification module 12, and this moment, the user only need send voice command (namely bark out want see channel designation) facing to miaow head 11.If the user 5 seconds with the interior order word that does not send voice command or send not within the lists of keywords 124 at sound identification module 12 time, described sound identification module 12 is closed (safe and power saving setting) automatically.When if the voice command that the user sends is errorless, for example, the user sends the voice command of " CCTV1 ", this voice command is converted to the signal of telecommunication by the miaow head and passes to sound identification module 12(LD3320) signal input pin, it is phonetic feature by spectral conversion that the spectral conversion unit 121 of sound identification module 12 is received behind the voice command content, sends to described voice match unit 123 after by feature extraction unit 122 phonetic feature being extracted then and mates.In described voice match unit 123, the keyword of presetting in the phonetic feature that receives and the lists of keywords 124 is mated, and with the keyword of Optimum Matching (as, CCTV1) as recognition result.Then the recognition result that obtains is sent to the main control MCU 13 of remote controller, described MCU13 is just according to the corresponding relation that configures in advance (being that the keyword of MCU register memory storage is to the corresponding relation tabulation of infrared coding), described recognition result is converted to corresponding infrared encoded signal, and drive described infrared transmitting tube 14 infrared encoded signal is exported to set-top box, receive the back by set-top box and realize changing fast and accurately platform.
