ELECHOUSE 声音识别模块 V3 说明书
Voice Recognition Module V3 Speak to Control (Arduino compatible)OverviewELECHOUSE Voice Recognition Module is a compact and easy-control speaking recognition board.This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.What’s new?We already have Voice Recognition module V2. It supports 15 commands in all and only 5 commands at the same time.On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at thesame time.On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.Parameter●Voltage: 4.5-5.5V●Current: <40mA●Digital Interface: 5V TTL level for UART interface and GPIO●Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface●Size: 31mm x 50mm●Recognition accuracy: 99% (under ideal environment)Feature●Support maximum 80 voice commands, with each voice 1500ms (one or two words speaking)●Maximum 7 voice commands effective at same time●Arduino library is supplied●Easy Control: UART/GPIO●User-control General Pin OutputTerminology●VR3 -- Voice Recognition Module V3●Recognizer -- a container where acting voice commands (max 7) were loaded. It is core part ofvoice recognition module. For example, it works like “playing balls”. You have 80 players in your team. But you could not let them all play on the court together. The rule only allows 7 playersplaying on the court. Here the Recognizer is the list which contains names of players working on the court.●Recognizer index -- max 7 voice commands could be supported in the recognizer. Therecognizer has 7 regions for each voice command. One index corresponds to one region: 0~6●Train -- the process of recording your voice commands●Load -- copy trained voice to recognizer●Voice Command Record -- the trained voice command store in flash, number from 0 to 79●Signature -- text comment for record●Group -- help to manage records, each group 7 records. System group and user group aresupported.InstructionHere we will introduce the Arduino Library and VR3 ProtocolFor ArduinoPrepare●Voice Recognition V3 module with microphone●Arduino board (UNO recommended)●Arduino Sensor Shield V07 (optional)●Arduino IDE●Voice Recognition V3 library (Download zip file)Hardware and Software Preparation1.Connect your Voice Recognition V3 Module with Arduino, By Default:2.Download VoiceRecognitionV3 library. (download zip file or use g i t c l o n eh t t p s://g i t h u b.c o m/e l e c h o u s e/V o i c e R e c o g n i t i o n V3.g i t command)3.If using zip file, extract VoiceRecognitionV3.zip to A r d u i n o S k e t c h\l i b r a r i e s folder, or if youuse g i t c l o n e command copy VoiceRecognitionV3 to A r d u i n o S k e t c h\l i b r a r i e s .Train1.Open vr_sample_train (File -> Examples -> VoiceRecognitionV3 -> vr_sample_train)2.Choose right Arduino board(Tool -> Board, UNO recommended), Choose right serial port.3.Click Upload button, wait until Arduino is uploaded.4.Open Serial Monitor. Set baud rate 115200, set send with Newline or Both NL & CR.5.Send command s e t t i n g s(case insensitive) to check Voice Recognition Module settings.Input s e t t i n g s, and hit E n t e r to send.6.Train Voice Recognition Module. Send s i g t r a i n0O n command to train record 0 with signature"On". When Serial Monitor prints "Speak now", you need speak your voice(can be any word, meaningful word recommended, may be 'On' here), and when Serial Monitor prints "Speak again", you need repeat your voice again. If these two voice are matched, Serial Monitor prints "Success", and "record 0" is trained, or if are not matched, repeat speaking until success.What is a signature? Signature is a piece of text description for the voice command. Forexample, if your 7 voice command are “1, 2, 3, 4, 5, 6, 7”, you could train in the following way: s i g t r a i n0o n es i g t r a i n1t w os i g t r a i n2t h r e es i g t r a i n3f o u rs i g t r a i n4f i v es i g t r a i n5s i xs i g t r a i n6s e v e nThe signature could be displayed if its command was called.When training, the two led on the Voice Recognition Module can indicate your training process.After sending the training command, the SYS_LED (yellow) is blinking fast which remind you to get ready. Speak your voice command as soon as the STATUS_LED (red) light lights on. The recording process ends once when the STATUS_LED (red) lights off. Then the SYS_LED is blinking again, get ready for next recording process. When the training process ends successful, SYS_LED and STATUS_LED blink together. If the training fails, SYS_LED and STATUS_LED blink together, but quickly.7.Train another record. Send s i g t r a i n1O f f command to train record 1 with signature "Off".Choose your favorite words to train (it can be any word, meaningful word recommended, may be'Off' here).8.Send l o a d01 command to load voice. And say your word to see if the Voice RecognitionModule can recognize your words.If the voice is recognized, you can see.9.Train finish. Train sample also support several other commands.Control LED SampleHere we show a simple example showing how to control the LED on Arduino board(connecting to pin13)through voice commands.Before this example,you need to train the VR module first in the way as vr_sample_train shows above. Use the following commands:●s i g t r a i n0o n Train the voice command used to light on the LED●s i g t r a i n0o f f Train the voice command used to turn off the LEDThen following the steps:1.Open vr_sample_control_led (File -> Examples -> VoiceRecognitionV3 ->vr_sample_control_led)2.Choose right Arduino board (Tool -> Board, UNO recommended), Choose right serial port.3.Click Upload button, wait until Arduino is uploaded.4.Open Serial Monitor. Set baud rate 115200.5.You will see the indication:Speak the voice commands you train above and check the status of LED on Arduino.vr_sample_multi_cmdThis sample shows how to use multi commands (more than 7 commands). This sample use RECORD 0 (the first voice command) to switch between the 2 command 'groups' (not Voice Recognition Group Function). Group 1 is made of RECORD 0, 1, 2, 3, 4, 5, 6. A nd second group is made up of RECORD 0, 7, 8, 9, 10, 11, 12 .Note: Before start this sample, you need train your Voice Recognition module first, and make sure that all records from 0 to 12 should be trained.vr_sample_check_baud_rateThis sample is used to check the baud rate, when you forgot your custom settings.vr_sample_bridgeThis example allows you to send VR3 protocol commands to VR3 board. For more detail, please refer to Protocol . Note: do not input Frame Head, Frame Length, Frame End, only need input Frame Command and Frame Data. For example, Check Recognizer Command is "AA 02 01 0A" for all, here you only need input 01.Example:1.Enable Arduino Serial monitor "Send with newline", Baud rate 115200.2.Input "01" to "check recognizer".3.input "31" to "clear recognizer"4.input "30 00 02 04" to "load record 0, record 2, record 4"Please refer to libref.pdf to get more information about functions of this library.VR3 ProtocolVR3 protocol contains basic commands to control VR3 boards. For those who use VR3 with other MUC rather than Arduino, VR3 protocol is very helpful.All the commands of VR3 are sent through serial port in HEXADECIMAL FORMAT.Example are supplied with this serial port tool: Access PortTo connect VR3 to PC, this USB-TTL module tool: USB-TTL Module with 5V or 3.3VBase FormatControl| Head (AA) | Length| Command | Data | End (0A) |Length = L(Length + Command + Data)Return| Head (AA) | Length| Command | Data | End (0A) | Length = L(Length + Command + Data)NOTE: Data area is different with different with commands.

测通过 R570~R572、R580的数字音频信号波形，如图1所示，发现R572处波形异常，怀疑此通道有故 障。
用导线跨接主芯片与R572后，故障排除。
此 故障为电源板质量问题引起。
I2C四路信号正常 时，其信号电压均在1.6V左右。
提示：检修TAS5711组成的功放电路时，首 先测⑬、⑭脚总线（SDA、SCL)电压，正常值约为 3.2V,若总线电路有故障，会导致无伴音或声音时 好时坏。
此总线通过电阻R189、R191上拉3.3V 并与调谐器U11㉙、®脚内电路通讯，也与 E E P R O M存储器U101相连。
当总线异常时，须查上述总线电路。
另外，⑭脚是总线地址识别端，经R661接 3.3V正常时为高电平。
⑲脚为待机模式控制端，外接Q11、Q10关机静音和Q48静音控制电路，正常时为高电平，若为低电平，功放不工作。
@脚(复位）外接电平转换电路Q14,正常时该脚为高 电平。
例2: —台47E760A型机，开机后，右声道喇 »八中有交流声。
分析检修:根据故障现象分析,判定功放内部 R音频处理电路或R输出通道异常。
先检查功放芯片①、④脚外接元件C509、L38及C515、C232、C233,发现C233电容虚接，补焊后开机，伴音恢 复正常。
例3:—台42E760A型机，冷机开机花屏，包括开机画面分析检修:根据经验，此故障与图像格式转换及D D R电路有关。
