Abstract
The utility model provides a controllable voice control system composed of a microphone, an operational amplifier, an anti-aliasing filter, an analog to digital (A/D) converter, a digital signal processing control core and a microprogrammed control unit (MCU). The microphone is used for inputting audio signals; the operational amplifier is used for amplifying the audio signals input by the microphone; the anti-aliasing filter is used for filtering the audio signals amplified by the operational amplifier; the A/D converter is used for performing analog-to-digital conversion to the filtered signals; the digital signal processing control core is used for processing and recognizing the digital signals output by the A/D converter; and the MCU is used for receiving the processing and recognizing results from the digital signal processing control core, and controlling an executive mechanism to perform corresponding controlling actions according to the relevant recognizing results. The controllable voice control system is capable of processing and operating the complex voice signals quickly by aid of the digital signal processing control core, high in recognition accuracy and simple in structure.
Description
Technical field
The utility model relates to electronics art field, and a kind of controlled speech control system is provided.
Background technology
Along with the continuous development of science and technology, various voice control technologys and device continue to bring out, generally in recent years; The voice control procedure is divided into basically: parts such as voice collecting, speech recognition, voice command generation, the transmission of voice control signal, control action execution, and wherein most critical and difficulty is exactly speech recognition, because the complicacy of voice signal; Speech recognition often need be carried out a large amount of computings; Than higher, the utility model adopts digital signal processing control core can be fast the voice signal of complicacy to be carried out processing operations, and accuracy of identification is high to the travelling speed of hardware and storage capacity requirement; Simple in structure; And the utility model adopt through button be provided with the unit with the typing voice be set to the data masterplate, to different use crowds, improved the discrimination of voice greatly.
The utility model content
The purpose of the utility model is to provide a kind of accuracy of identification high, speech control system simple in structure.
The utility model is for realizing that above-mentioned purpose adopts following technical scheme:
A kind of controlled speech control system; It is characterized in that: comprise the microphone that is used for sound signal input, be used to amplify the sound signal of microphone input operational amplifier, be used for the sound signal after amplifying through operational amplifier carry out the anti-aliasing filter of filtering wave filter, be used for carry out analog-to-digital A/D converter through filtered signal, be used for the digital signal of A/D converter output carry out processing and identification digital signal processing control core, be used for the MCU of receiving digital signals processing controls core processing recognition result, said MCU makes corresponding control action to corresponding recognition result control executing mechanism;
The voice alerting unit that also comprises prompting user operation;
Comprise that also the button that is used to be provided with the typing voice is provided with the unit; Button is provided with the unit controls mode of operation; Under the prompting of voice alerting unit,, the voice of typing are complementary through the action that button is provided with unit setting and topworks through microphone typing user speech;
Also comprise the Flash storer of the voice masterplate data that are used to deposit masterplate data and user's typing and use and the SRAM that deposits ephemeral data that said Flash all is connected with digital signal processing control core with SRAM.
The utlity model has following beneficial effect:
The utility model adopts digital signal processing control core can be fast the voice signal of complicacy to be carried out processing operations; And accuracy of identification is high; Simple in structure; And the utility model adopt through button be provided with the unit with the typing voice be set to the data masterplate, to different use crowds, improved the discrimination of voice greatly.
