Description
Technical field
The utility model relates to communication technical field, specifically a kind of speech recognition equipment.
Background technology
Can allow machine exchange with the mankind, make machine understand human voice, be our dream for a long time.Along with the development and progress of speech recognition technology, we are constantly striding forward towards this dream.Now the mankind can become literal to store or convert to the order execution of operating machine by converted machine voice.In following 10 years, speech recognition technology will enter every field such as industry, household electrical appliances, communication, automotive electronics, medical treatment, home services, consumption electronic product.
The Embedded Speech Recognition System technology is the part of speech recognition technology, and it refers to not the speech recognition technology of operation on computers.This technology has good development prospect in a lot of fields.Built-in speech recognition system is low with its cost, use characteristics such as flexible such as toy, and aspects such as Industry Control all are widely used.
At present, built-in speech recognition system is divided into voice collecting, speech recognition, three parts of control output more.The speech recognition part is made up of three parts the feature extraction and the aspect ratio of end-point detection, voice again.The action that needs work is judged by the said voice command of identification user by system.Different systems end-point detection, signal characteristic extract and aspect ratio on the method used different with strategy, caused the different of discrimination and service condition.Especially under the more intense environment of noise, discrimination will have very big difference.The judgement that makes the mistake easily under the low situation of discrimination.
Summary of the invention
The utility model is in order to overcome the shortcoming of prior art, proposes a kind of rational in infrastructure, speech recognition equipment that False Rate is low, safe and reliable.
The technical measures that the utility model adopts are:
A kind of speech recognition equipment, comprise microphone, power supply, control circuit board, show output device, it is characterized in that power supply is connected with control circuit board, microphone is connected with control circuit board, show that output device is connected with control circuit board, control circuit board is provided with the voltage modulated module, analog-to-digital conversion module, the recognizer module, main control module and control module, wherein the voltage modulated module is connected with analog-to-digital conversion module, analog-to-digital conversion module is connected with the recognizer module, main control module is connected with control module respectively with the recognizer module, and main control module is connected with analog-to-digital conversion module.
The utility model in use, the interlock circuit of power supply on control circuit board given whole device power supply, carry out the collection of voice signal through microphone, and the voltage modulated module that the signal that collects is sent on the control circuit board carried out rough handling, the output terminal of voltage modulated module is connected with analog-to-digital conversion module, enter the recognizer module after the information via analog to digital conversion, carry out speech recognition, result after the identification is admitted to control module, control module is after master control module controls, to show that output information sends into the demonstration input equipment, thereby reach man-machine communication's purpose, the utility model can reduce False Rate effectively, recognizing voice has rational in infrastructure, easy to use, the significant advantage of grade simple to operate.
