Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of wireless interspeaker of speech recognition controlled is provided, send " voice command " by the user, realize wireless interspeaker translated channel, wait for standby, send operating functions such as conversation, scanning, monitoring.
Speech recognition wireless interspeaker of the present utility model is to realize like this, it comprises machine case, be arranged on microprocessor 1, high frequency transmitter/receiver circuit unit 3 in the housing, comprise the telephony unit of receiver 7 and loud speaker 5, its difference is, is connected to voice recognition unit 8 between microcontroller 1 and telephony unit.
Wherein, connect command switch 2 on the microcontroller 1.
Wherein, voice recognition unit 8 contains speech chip 9, articulates big volume, external memory 10 on the speech chip.
Wherein, voice recognition chip 9 adopts the embedded speech chip, adopts SD (Speaker-Dependent) mode to work, and will carry out the order training before the user uses first.
The utility model wireless interspeaker has been compared following advantage with existing technology:
1, do not use or only use a fewer keys, simplified the traditional design of intercom, saved components and parts, reduced cost.
2, overcome in the manual difficulty of some place inconvenience, made things convenient for the user.
3, Ge Xinghua speech recognition is convenient to maintain secrecy and safe handling.
Description of drawings
Fig. 1 is the circuit module figure of the utility model speech recognition wireless interspeaker.
Fig. 2 is the voice recognition unit circuit diagram of an exemplary embodiments of the utility model speech recognition wireless interspeaker.
Embodiment
Be described in further detail the utility model below in conjunction with drawings and Examples.
Shown in Figure 1 is the circuit module figure of the utility model speech recognition wireless interspeaker, and the voice recognition unit 8, high frequency that comprise telephony unit, microcontroller 1, are controlled by microcontroller 1 receive transtation mission circuit unit 3; Telephony unit contains receiver 7, loud speaker 5;
Loud speaker 5 receives transtation mission circuit 3 with high frequency through voice amplifier 4, receiver 7 respectively through preamplifier 6 and joins;
Voice recognition unit 8, also link to each other with telephony unit;
Be connected to a command switch 2 on the microcontroller 1.
Voice recognition unit 8 of the present utility model contains an Embedded Speech Recognition System chip 9, articulates big volume, external memory 10 on the speech chip.
This voice recognition chip adopts the special voice recognition chip of high performance-price ratio, and adopts SD (SpeakerDependent) technology, makes product can not be subjected to the influence of territorial dialect and age of user, sex, has guaranteed that product has good identification effect.The user is as long as carry out " order training " before using first after, promptly available tone of speaking usually sends instruction, manipulates.Recognition accuracy reaches more than 98%.This use that just makes this intercom is personalization and practicability more.
Considering the custom that the user uses, in the utility model exemplary embodiments, structurally, kept several conventional keys, is respectively to send key, scanning key, monitoring key.Like this, except using " voice command ", can also (directly use button operation) in a conventional manner and realize " transmission ", " scanning ", " monitoring " function.
The utility model should carry out " voice command " training by the user earlier, so that its personalization before initial the use.That is to say that the user will send to voice unit by the receiver biography with the order of intending using, by the voice unit storage, as template, the usefulness that contrasts during for speech recognition.This process is referred to as " training " process.
Operation principle of the present utility model is such:
Connect command switch 2, then a low level signal is sent to microcontroller 1, and microcontroller 1 receives this signal, then sends order to voice recognition unit 8, waits for that the user sends " voice command ", promptly enters " voice command " state;
After the user sends accordingly " voice command ", should " voice command " via receiver 7, send into voice recognition unit 8, compare to determine with " order " of having stored in the voice recognition unit 8; Voice recognition unit 8 sends a code signal to microcontroller 1 according to the result who judges;
After microcontroller 1 receives this code signal, through decoding, will send the control signal corresponding tremendously high frequency and receive transtation mission circuit 3, the control high frequency receives transtation mission circuit 3 work.
Shown in Figure 2 is the circuit diagram of an exemplary embodiments of the utility model speech recognition wireless interspeaker.This embodiment on the basis of conventional wireless interspeaker, has increased a speech identifying function.It is just the same with the high frequency reception transtation mission circuit of common intercom that its high frequency receives transtation mission circuit, do not do any change.
U1 is a microprocessor chip, adopt BF3248 model chip, it is the main control chip of the utility model speech recognition wireless interspeaker, except finishing high frequency is received the various control operations of transtation mission circuit, also control the work of speech chip U2 by three order wire M0, M1, M2 and five signal line X0, X1, X2, X3, X4.
U2 is a speech chip, adopts YS3460 model embedded chip, and the voice signal that it can directly be sent receiver here carries out preposition amplification earlier, and then carries out sample quantization and data processing, sets up sound template.Because this speech chip has adopted advanced language data process technology, its discrimination improves a lot, and can satisfy general practical requirement fully,
Speech chip U2 generally is to be in the sleep for electricity saving state, in case have signal to pass on MO, M1, the M2 line, promptly is waken up work.
U3 is an external program memory that is articulated in speech chip U2, the working procedure of having stored the U2 chip, speech processing module and " suggestion voice " etc.
U5 is an external data memory that is articulated in speech chip U2, adopts 64kbit SEEPROM24C64, is articulated on the speech chip, mainly when speech chip U2 works, dynamically stores speech data.Sound template when training, and other ephemeral data as user speech.
This embodiment in use, the user turns on the power switch, intercom promptly enters " waiting for standby " state, this moment, the user can select to use " voice command " operation or conventional button operation.If press " scanning key " and " monitoring key " simultaneously, then connect command switch 2, intercom promptly starts speech identifying function, enters the state of " voice command ".
" voice command " that the user sends sends into speech chip U2 through receiver, can be identified (comparing) with the command template that is stored in the voice unit, speech chip U2 will be according to the result of identification, produce one group of respective coding, send it back microprocessor chip U1 through holding wire X0, X1, X2, X3, X4; U1 sends the instruction tremendously high frequency and receives transtation mission circuit according to the signal that returns, and can finish user's corresponding " voice command " work.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection range of the present utility model.
