Abstract
The utility model relates to a button-free wireless carrier signal receiving and processing device with voice recognition control, which comprises a radio signal receiving module, a power amplifier and a speaker which are sequentially connected. The device further includes a central processing unit CPU, and a storage and a digital signal processor DSP which are connected with the central processing unit CPU, wherein the central processing unit CPU is connected with the radio signal receiving module, the radio signal receiving module is also connected with the central processing unit CPU via an A/D converter, and the digital signal processor DSP is connected with a voice input device sequentially through an A/D converter and a voice amplitude gain controller. A user can perform operations such as starting on, shutting down, frequency modulation, amplitude modulation and the like on the device through voice recognition control instructions, and the device has simple and convenient operation and can be used by people with certain disabilities.
Description
Technical field
The utility model relates to wireless carrier signal receiving and processing device field, is specifically related to a kind of wireless carrier signal receiving and processing device that does not have the key-press and voice identification control.
Background technology
The wireless carrier signal receiving and processing device product of Xiao Shouing is a feast for the eyes on the market, these devices all are to accept radio signals by the radio receiver signal receiver module, radio signals amplifies to be gone out by loudspeaker plays by power amplifier again, and certain operations such as wireless start, shutdown, frequency modulation, amplitude modulation need the user to control by manual operation.Yet, in society, also existing many handicapped the elderlys or disabled person, they are not easy to finish some activities with hand, are very inconvenient by these devices of manual operation to them fully.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of wireless carrier signal receiving and processing device of the no key-press and voice identification control of using for handicapped people is provided.
The purpose of this utility model is achieved in that a kind of wireless carrier signal receiving and processing device that does not have the key-press and voice identification control, comprise the radio receiver signal receiver module that connects successively, power amplifier and loud speaker, it is characterized in that: the utility model also comprises central processor CPU and the memory and the digital signal processor DSP that connect with this central processor CPU, central processor CPU connects with described radio receiver signal receiver module, described radio receiver signal receiver module also connects with this central processor CPU by A/D converter, and described digital signal processor DSP passes through A/D converter successively, voice amplitude gain controller connects with voice-input device.
Advantage of the present utility model is: be stored in the utility model is handled the instruction of user's speech recognition controlled successively by voice-input device through digital signal processor DSP, central processor CPU after with memory that central processor CPU connects in, when the user uses, as long as say the instruction of corresponding speech recognition controlled just can realize to the utility model start shooting, operations such as shutdown, frequency modulation, amplitude modulation, simple and convenient, can use for handicapped people.
Description of drawings
Fig. 1 is the utility model functional-block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model discloses a kind of wireless carrier signal receiving and processing device that does not have the key-press and voice identification control, comprise the radio receiver signal receiver module that connects successively, power amplifier and loud speaker, the utility model also comprises central processor CPU and the memory and the digital signal processor DSP that connect with this central processor CPU, central processor CPU connects with the radio receiver signal receiver module, the radio receiver signal receiver module also connects with this central processor CPU by A/D converter, and digital signal processor DSP passes through A/D converter successively, voice amplitude gain controller connects with voice-input device.
Memory comprises data storage and program storage in the utility model, program code leaves in the program storage, the back automatic program code read data of central processor CPU that power on are first also finished D/A in the central processor CPU the inside and are changed, and audio frequency is gone out by loudspeaker plays by power amplifier then; The code of various phonetic control commands leaves in the program storage, when the system requirements user and then reads the instruction of various speech recognition controlled, corresponding speech recognition controlled instruction will be taken over the speech recognition controlled instruction code in the original program memory, and the new speech recognition controlled instruction code that is produced by the user just is kept in the data storage; Voice-input device is that the user sends instruction and takes over the platform of control of product power, the voice that voice-input device receives at first enter voice amplitude gain controller and generate the moderate voice signal of amplitude, voice signal is finished analog-to-digital conversion through A/D converter then, the front-end processing that the digital signal that produces enters digital signal processor DSP, according to the principle of acoustic model and the feature written program of language model phonetic control command is discerned processing, thereby final synthetic data flow goes further error correction to produce utilizable control routine by central processor CPU.The user is when using the utility model, and the speech recognition controlled instruction of sending with face produces the same control effect with us with the hand keypad.
Because the utility model is when playing, the voice signal in radio station can enter into central processor CPU by voice-input device, therefore the voice signal in radio station also will enter into central processor CPU through A/D converter and handles, be used for carrying out " noise reduction ", enter voice-input device and cause misoperation of the present utility model in order to avoid loud speaker sends acoustic signals such as " shutdown " with the voice signal in the radio station of voice-input device input.
For the ease of carrying, it is less that volume of the present utility model can be provided with, on its panel without any function button.Product powers on first, it can play products instruction automatically, one section product function control voice command is arranged then, and as long as the user follows every voice command to read aloud 3～5 times and just the speech recognition controlled instruction can be stored in the data storage according to prompting.After installing battery, when wanting to listen, the user, do not say that facing to it " shutdown " is just passable when not wanting to listen as long as say " start " facing to the utility model.Because be the product that specific group uses, so the function that can control is less, the utility model has only the function of " start ", " shutdown ", " frequency modulation " (FM wave band), " amplitude modulation " (medium-wave band), " making progress " (upwards sweeping platform), " downwards " (sweeping platform downwards), " loudly " (volume is transferred loud), " little sound " (volume is turned sound down).
