Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in more detail.
Main thought of the present invention is by increase speech control module on the basis of existing set-top box, by this module receive and the recording of storage user's voice and with specific channel corresponding stored, when the user sends phonetic control command, by comparing, find out matched data and carry out corresponding operating with the storage data.
As shown in Figure 1, be the internal structure of speech control module, this module comprises high-gain microphone, RC filter network, analog baseband signal processor, digital baseband signal processor, the memory that links to each other successively.
Wherein, the high-gain microphone is called built-in transmitter again, and built-in transmitter is converted into weak electric signal with voice signal, carry out filtering by the RC filter network after, directly insert the analog baseband signal processor.
Analog baseband signal processor inside comprises: audio frequency amplifier, a-d converter, digital filter etc.After analog voice signal is imported into, be sent to audio amplifier circuit earlier, after amplifying, deliver to a-d converter, analog signal conversion is become digital voice signal, digital voice signal can be delivered to the interface with the digital baseband signal processor behind sampling rate converter unit and digital high-pass filter.
The digital baseband signal processor, double controller and the digital signal processor done of digital baseband signal processor.The digital baseband signal processor is responsible for voice digital signal is carried out with concrete operational order corresponding one by one, and under voice typing pattern, it deposits digital audio and video signals in memory; Under the voice control model, the data that keep in advance in voice signal and the memory are compared coupling, transmit operation instruction.
Memory is used for storing pre-set phonetic order.
As shown in Figure 2, be the inventive method user speech typing flow chart.
When the user presses the typing button, set-top box is in voice typing pattern.If this moment, television channel just in time switched to one in central authorities, point out " please import channel selection order voice " on the video screen this moment, the user we can say " one " or " one in central authorities ", after user's voice is imported by microphone, after the analog baseband signal processor processing, under the control signal that the digital baseband signal processor sends, deliver to the digital baseband signal processor, processor is by certain speech characteristic parameter extractive technique, the characteristic parameter extraction of voice is come out, store in the memory and go in " one in central authorities " corresponding address.After the phonetic order typing is finished, turn off the typing button.The speech characteristic parameter extractive technique is a prior art, and linear prediction (LP) analytical technology is present widely used Technique of Feature Extraction, and many successful application systems all adopt the cepstrum parameter that extracts based on the LP technology.But linear prediction model is the pure mathematics model, does not consider the processing feature of human auditory system to voice.Mel parameter and the perception linear prediction cepstrum that extracts based on perception linear prediction (PLP) analysis have been simulated the processing feature of people's ear to voice to a certain extent, have used some achievements in research of human auditory system perception aspect.Experiment showed, and adopt this technology, the performance of speech recognition system improves.
Wherein, the analogsimulation baseband signal processor is as follows to the Signal Processing process: the built-in audio amplifier circuit of analog baseband signal processor amplifies the weak electric signal that receives, and sends to a-d converter; A-d converter is a digital audio and video signals with analog signal conversion, and carries out the sampling rate conversion, the high-pass filtering conversion, thus finish the Signal Processing process.
As shown in Figure 3, open control button, set-top box enters the controlled pattern of voice.If set-top box receives the voice with previous typing coupling, so just carry out operating accordingly with these voice.For example, television channel is in central authorities' 4 covers, and this moment, the user said " one " " central authorities one " (this depend on previous user's typing what is) in other words, and set-top box will automatically switch to one in central authorities.User's voice is input to set-top box by microphone, (processing procedure during with above-mentioned voice typing is consistent after the processing through the analog baseband signal processor, repeat no more), become audio digital signals, after delivering to the digital baseband signal processor, analyze extractive technique by the Mel parameter with based on perception linear prediction (PLP), the characteristic parameter of voice is extracted out, compare successively with the data of storing under the typing pattern, if find the data of coupling, so just, send channel information to channel control circuit according to the channel of the address correspondence at data place.If the voice that receive are not just operated with the not coupling of previous typing.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
