Grove Speech Recognizer Kit for Arduino

The Grove Speech Recognizer Kit for Arduino is designed for prototype of Smart Home which includes some basic home elements such as Speech Recognizer, Infrared Emitter. You can learn the functions and applications of Speech Recognizer quickly via this kit, the guideline shows some common demos, let's say you can play music via your speak command 'Play music', or turn on the light according to the corresponding command.

Application

How to turn on the TV

Sometimes, we want to control something by our voice, such as TV, air condition. Those devices are controlled by Infrared Remote controller, so we need to know what the code of each button of infrared remote controller first, and then put the code under our program. Finally your voice could trigger those button codes and you can control those devices like infrared remote controller.

Before create this demo you should prepare some necessary components:

  • Grove - Infrared Receiver

  • Grove - Infrared Emitter

  • Grove - Speech Recognizer

  • Base Shield

  • Arduino UNO

  • Infrared Remote controller

Get code of a infrared remote controller via Grove - Infrared Receiver

Download necessary libraries from github : IRSendRev ,pay attention to the path of your libraries: .../arduino/libraries

  • Now open the example file of "recv" : File --> Sketchbook --> libraries --> IRSendRev --> recv.

  • Upload the program to your Arduino UNO.

  • Plug Base Shield onto the Arduino UNO,and plug the Grove - Receiver onto the D2 port of Base Shield.

Also you can change another port while modifying the definement of pin. </dd></dl>

  • Open the monitor of Arduino UNO.

Press a button of any Infrared Remote Controller, you'll get the detailed information code of the button, see following:

Write down the detailed information of the button you want to press. Following are the information of a button:

Modify the IRSend program

Now we can use the previous information code of a button.

  • Open the example file of "send" : File --> Sketchbook --> libraries --> IRSendRev --> send.

  • Upload the program to your Arduino UNO.

  • Plug Base Shield onto the Arduino UNO,and plug the Grove - Receiver onto the D3 port of Base Shield.

First we need modify the default information of the button:

Modify those information according to the previous one you wrote:

You can observe that:

So you can note or delete those two lines.

Of course you can also define many buttons:

Add Speech Recognizer to your IRSend program

  • It's very simple to use Speech Recognizer alone, please see the wiki of it first.

We can choose what buttons we need according to the table<ref>Table of return value, Grove - Speech Recognizer</ref> of return value of Speech Recognizer. Following is the table of return value:

The following example uses two commands: "Turn of the TV" and "Turn off the TV"

  • After reading, we can embed the program of Speech Recognizer in the IRSend program. See the following completed program:
