Description
Technical field
The invention belongs to field of speech recognition more particularly to a kind of speech recognition systems for intelligent sound customer service robot
System.
Background technology
With the rapid advances of science and technology, various human-computer interaction products have entered in people’s lives, greatly
Facilitate people’s lives, interactive voice is Human communication and exchanges in information most easily means and most important media,
For a long time, people are intended to look for a kind of interactive mode of new approach the solution mankind and machine, it is desirable to machinery equipment energy
" listening " understands that the voice messaging of the mankind interacts, and identifies its meaning and responds, to make corresponding actions, such interactive mode
It can more be received by user, traditional interactive mode such as original keyboard, button, switch, the voice based on unspecified person is replaced to know
Other technology already becomes an important development direction and research hotspot for human-computer interaction new paragon.The identification of voice signal is related to crowd
Multi-subject knowledge system, since voice signal has the characteristics that contain much information, uncertain, dynamic and successional, in voice
The phase process data volume such as pretreatment, feature extraction of signal is very big, the processing capacity of Processing Algorithm and hardware to software
There are higher requirement, tradition to realize that voice signal identifies using the platform of the high process performances such as PC machine or industrial personal computer, but hard
The excessively high development for having hindered speech recognition technology of software development cost.
Invention content
Present invention seek to address that the above problem, provides a kind of speech recognition system for intelligent sound customer service robot.
A kind of speech recognition system for intelligent sound customer service robot, it is characterised in that know including controller, voice
Other module, memory module, power module and interactive module；Wherein sound identification module is connected with controller；Memory and control
Device processed is connected；Power module is connected with controller；Interactive module is connected with controller；Interactive module includes input electricity
Road, output circuit and indicating circuit.
In order to further improve the using effect of the present invention, the controller adopts TSSOP20 173MIL microcontrollers in order to control
Device.
In order to further improve the using effect of the present invention, the sound identification module adopts ISD1820PY speech recognition cores
Piece.
In order to further improve the using effect of the present invention, the working frequency of the controller is 96MHz.
In order to further improve the using effect of the present invention, SD card interface, input button are provided in the interactive module
And USB interface.
In order to further improve the using effect of the present invention, the memory module is HD816 mobile hard disks.
The present invention commonly uses the mode of electronic component by using some, and more single language is realized using Embedded structure
Sound identifying system, circuit system are simple, cost-effective, it may be convenient to which embedded custom system, building block system build flexible practicality, have
There are the extensive market demand and application prospect.
Specific implementation mode
Including controller, sound identification module, memory module, power module and interactive module；Wherein sound identification module
It is connected with controller；Memory is connected with controller；Power module is connected with controller；Interactive module and controller phase
Connection；Interactive module includes input circuit, output circuit and indicating circuit.
A kind of speech recognition system of the present invention, the controller use TSSOP20 173MIL microcontrollers in order to control
Device, internal high-speed memories possess abundant I/O mouth resources and the peripheral hardware for being linked to two APB buses.Include 12b's
ADC, general 16b timer, further include the buses such as I2C, SPI, USART, USB, CAN or serial communication interface, resource in piece
With expansion interface all very abundants, which is specially to be designed to meet high stability, low-power consumption, real-time, Gao Xing
Valence than embedded product application.The core chip can meet the functional requirement of signer-independent sign language recognition, using mutually powered-down
Road constitutes the minimum system of TSSOP20 173MIL, be also integrated in hardware PCB function draw pin output interface, SD card interface,
USB download debug circuit, user key-press, power circuit etc..The sound identification module uses LD3320 voice recognition chips,
The chip is the special chip of signer-independent sign language recognition, and inside has been integrated with voice recognition processor and some signal modulations
Circuit possesses high performance A/D converter, D/A converter, microphone audio signal input interface, audio decoder output interface
It is only needed with the good lists of keywords to be identified of software editing Deng, user, ISD1820PY maximums can support 150 keywords
Sentence, is not transmitted to these row in chip in the form of character, so that it may to carry out degree of approximation analysis to voice signal to be identified,
Result is exported after identification.The working frequency of the controller is 96MHz.SD card interface, input are provided in the interactive module
Button and USB interface.The system bulk is small and exquisite, built-in module unit can be used as to incorporate in subscriber's line circuit or board, on
After electricity TSSOP20 173MIL internal processes carry out program initialization, SD card file system initialization, ISD1820PY initialization,
It then waits for identification audio to receive, output response message or decoding audio, final to realize building block system functional group after the completion of identification
The repertoire of part.
