Abstract
The invention, which relates to the set-top box field, provides a voice controlling-based set-top box that comprises a set-top box body and a voice identification control unit arranged in the set-top box body. The voice identification control unit includes a pre-processing unit, a voice identification unit and a set-top box main controller unit, wherein the three units are connected in order; the pre-processing unit includes a microphone, a signal amplifier, an anti-alias filter, and an A/D converter, wherein the components are connected in sequence; the voice identification unit consists of a DSP processor, an SDRAM storing an initializing program and a voice comparison module, a Flash unit for placing and storing ephemeral data during system running, and a key unit for arranging and training the voice comparison module; the DSP processor is also connected with a monitoring module circuit capable of monitoring a working state of the DSP processor in real time; and when an exceptional working state occurs at the DSP processor, the monitoring module enables the DSP processor to realize resetting. And the provided set-top box plays a role as a set-top box.
Description
Technical field
The present invention relates to a kind of set-top box, a kind of a kind of voice control STB that can its operating state of term sound control system is provided.
Background technology
Along with progress of science and technology, Digital Television has obtained popularizing, and present set-top box mainly is to adopt manually control, by manual control button input various command, makes that set-top box can carry out that channel is better according to user's requirement, volume adjusting etc.But because set-top box can be from strength to strength, the number of keys on remote controller or the set-top box increases gradually, increased the input of producing, and, for special populations such as blind person, hand are handicapped, maybe can not control set-top box with hand owing to can not see the button on the remote controller, use very inconvenient.
Summary of the invention
The present invention is directed to the deficiencies in the prior art a kind of a kind of voice control STB that can control its operating state by voice is provided.
The present invention is by the following technical solutions for achieving the above object:
A kind of voice control STB, it is characterized in that: comprise the set-top box body, be arranged on the speech recognition controlled unit in the set-top box body, described speech recognition controlled unit comprises pre-process unit, voice recognition unit and the set-top box Main Control Unit that is linked in sequence; Described pre-process unit comprises microphone, signal amplifier, frequency overlapped-resistable filter and the A/D converter that is linked in sequence; The Flash of the ephemeral data when described voice recognition unit comprises dsp processor, stores the SDRAM of initialize routine and voice comparing module, is used for the storage system operation, be used for arranging and the push-button unit of training utterance comparing module; Described dsp processor also is connected with the monitoring module circuit that can monitor the dsp processor operating state in real time, and monitoring module resets dsp processor when unusual when the dsp processor operating state occurs.Described DSP also is connected with for the loud speaker of playing recognition result.
In the such scheme, the A/D converter of described pre-process unit is connected with the dsp processor of voice recognition unit, and the dsp processor of described voice recognition unit is connected with the set-top box Main Control Unit.
In the such scheme, also comprise serial port circuit, described dsp processor is connected with described set-top box Main Control Unit by described serial port circuit and connects.
In the such scheme, described dsp processor adopts dsp processor to adopt the TMS320C6713 model.
In the such scheme, described A/D converter TLC320AD50C model.
In the such scheme, described Flash adopts the SST39VF400A storage chip.
The present invention has following beneficial effect:
Set-top box of the present invention has speech identifying function, changed the interactive model of people and set-top box, people only need open one's mouth, just can open or close program, change working interface, make people's both hands obtain liberation, make everyone can both operate and use set-top box, use easily for blind person and the handicapped people of hand especially.
Description of drawings
Fig. 1 is system block diagram of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing:
The present invention includes the set-top box body and be arranged on the interior speech recognition controlled unit of set-top box body, as shown in Figure 1, be divided into pre-process unit, voice recognition unit, set-top box Main Control Unit on the speech recognition controlled whole unit.
The pre-process unit comprises microphone, frequency overlapped-resistable filter, signal amplifier and the A/D converter that is linked in sequence.Microphone is used for gathering the voice command signal, the voice command signal that collects at first amplifies through signal amplifier, then by giving A/D converter behind the frequency overlapped-resistable filter elimination high-frequency interferencing signal, A/D converter is converted into digital signal with the analog voice command signal that collects, so that follow-up voice recognition unit uses.
Voice recognition unit comprises dsp processor, store the SDRAM of initialize routine and voice comparing module, the Flash of the ephemeral data when being used for the storage system operation, the push-button unit that is used for setting and training utterance comparing module, after dsp processor receives the digital speech command signal of sending here the pre-process unit, voice digital signal is handled, namely identify comparison by operation in the Flash memory initialize routine that arranges in advance and the voice comparing module that realizes storage or training, transmit control signal to follow-up set-top box Main Control Unit according to the recognition result that obtains then, the set-top box Main Control Unit is finished relevant action, switch as channel, the adjusting of volume, loud speaker is play recognition result in operation.
Described dsp processor also is connected with the monitoring module circuit that can monitor the dsp processor operating state in real time, and monitoring module resets dsp processor when unusual when the dsp processor operating state occurs.
