Description
Technical field
The present invention relates to phonetic recognization rate field tests, more particularly to a kind of auto navigation phonetic recognization rate tests work automatically
Tool.
Background technology
At present, speech recognition technology has been enter into industry, household electrical appliances, communication, automotive electronics, medical treatment, home services, consumer electronics
The every field such as product, such as auto navigation, the increase of speech identifying function greatly increases driving safety, but for language
The test of sound discrimination but not systematic method of testing.
At present phonetic recognization rate method of testing is substantially all and adopts manual testing, particularly in the test of auto navigation,
Tester also needs to be carried out under different automobilism speed according to the reading of the word of one word of entry one, and identical entry
Read, because impact of the engine sound to voice is different under friction speed, need separately measurement, so considerably increase
The workload of manual testing.In addition, being easily caused language because the tone of test man, sound decibel are inconsistent in test process
The result of sound discrimination is inconsistent.I.e. during whole test, need to put into substantial amounts of man power and material, but obtain
Test result but be cannot be completely convincing.
The content of the invention
The problem to be solved in the present invention be how to solve the test of current artificial speech work repeatability it is big, thereby increases and it is possible to because
The measured deviation that test man's difference is caused.
In order to solve the above problems, the invention provides a kind of auto navigation phonetic recognization rate Auto-Test System, including
Operation module and phonetic recognization rate automatic testing instrument, described operation module is connected with phonetic recognization rate automatic testing instrument,

Order is transmitted to processing module, additionally it is possible to shown processor feedack；
Described phonetic recognization rate automatic testing instrument is used to send sound to the signal processing from operation module, and collects
From the signal of auto navigation feedback.The entry for needing test is input into by unified input equipment, by speech recognition
Have the unified audio of standard after the process of rate automatic testing instrument carries out the conversion of sound to testing entry, can accomplish testing
Ensure the concordance of tone harmony cent shellfish size in journey during different vocabulary tests, exclude because the problem of test source itself is made
Into the measurement error in measurement process, measurement quality can be preferably improved, in addition testing tool can also do to auto navigation
The judgement for going out is recorded, greatly reduce on the whole existing manual testing waste time and energy and test quality difference the characteristics of, and
It is with low cost.
Phonetic recognization rate automatic testing instrument includes processing module and audio-frequency module, described processing module and operation module
Connection, processing module is connected with auto navigation, and described audio-frequency module is connected with processing module, wherein described processing module is used
In processing from operation module and the information of auto navigation, instruction is sent to audio-frequency module；Described audio-frequency module is used to process
From the signal of processing module, and send sound.Specific phonetic recognization rate automatic testing instrument includes two parts, it is therefore an objective to
In order to preferably divide the work, on the one hand processor passes to audio processing modules and carries out sending out after the responsible information to input is processed
Sound, also on the other hand is responsible for being collected the information that auto navigation feeds back, and operation mould will be fed back to after information processing
Block.
Audio-frequency module includes loudspeaker drive division and loudspeaker, and described loudspeaker drive division is connected with processing module, described loudspeaker
Be connected with loudspeaker drive division.The entry signal that audio-frequency module is sent by receiving processing module, is converted and amplifies Chinese idiom
Message number, drives loudspeaker to carry out the generation of sound.Sound source during analog voice in this way, allows in auto navigation and connects
Quiet down sound, measures judgement.
Processing module is connected with auto navigation by connection.The effect of connection connection is to allow auto navigation to be known
Not afterwards by the information of identification to processing module transmission, allow processing module to judge the result of speech recognition, preserve as survey
Examination data.
Connection type is serial ports or USB.Data transfer can be faster carried out using serial ports, and uses USB interface then
With bigger versatility and portability, two kinds of different connection types can carry out selection under different scenes and use.
Operation module is PC ends or mobile terminal.It is can quickly to carry out word using the benefit at PC ends or mobile terminal
The input of bar, is also convenient in addition direct processing module and is shown after feedback of the information so that operator can be readily understood by surveying
Data during examination
Processing module includes process chip, and described process chip is DSP, ARM or MCU.The above-mentioned chip enumerated is with place
Reason function, and is the common and conventional chip in foot position on the market, the characteristics of with versatility height, good stability, and price
It is relatively reasonable, can be cost-effective.
Audio-frequency module includes audio processing chip, and described audio processing chip is DSP, ARM or FPGA.It is above-mentioned to enumerate
Chip carries Audio Processing function, and is the common and conventional chip in foot position on the market, high with versatility, good stability
The characteristics of, and price is relatively reasonable, and can be cost-effective.
Processing module is provided with data output interface.Data output interface is provided with, can be by the generation in test process
Test data is derived, and facilitates tester to be for further processing data.
The present invention has following beneficial effect：
1. a large amount of repeater's power machinery work are reduced.By using mechanical sounding, the heavy labor of manual testing's voice is solved
It is dynamic.
2. the quality of detection is improve.Because by mechanical sounding, it is ensured that the effect of sounding, reducing because sounding is inaccurate
Or pronounce wrong and affect test result, it is ensured that the unitary variant of test.
3. the efficiency of detection is improve.Because using the character input modes of operation module, and word input can be direct
Input, greatly improves the efficiency of detection.
4. the trouble of artificial data record is reduced.In test process operation module can record automatically auto navigation institute it is defeated
The judgement vocabulary for going out, and judged with the vocabulary of input, and will determine that result automatically records, solve heavy record
Work.
