Hi, I am Mae. I am 8. I am making for science fair. I want to make a toy that LED lights up whenever the word "cluck" comes up from a sound box that is also attached to the Arduino. I don't know if this is possible. and I dont know how to start. please help. thank you.
How is the "sound box" wired to the Arduino? Posting a hand-drawn diagram is nice, but a written description would be valuable.
Have you experimented with a simple program that just turns an LED on and off?
Share with us the program (sketch) you are using now.

Is "cluck" the only sound that will come from your sound box? If so, then it may be easier to just use a microphone sensor to check for sound level.

Hi a7 , thank you for your reples. I saw this on youtube. I haven try it and need to ask my mom to get it:
My mom said to ask someone and make sure it is good idea first.
Hi paul, thank you. I don't want cluck to be the only sound. I want to record a message like "I am a chicken. Hear me cluck" and sound comes on when cluck. I want to put it in a duck toy and evil light comes out from the eyes.

That Youtbe project does playback not sound recognition.

Although, I have to caution that replicating what someone has already done isn't really unique.

Do you think you can program to tell the difference between "cluck", "duck", "muck" and any other "uck" sound?

You can see we are not clear on what your project is attempting to do.
A. Do you want to play a sound and light an LED when your project hears a cluck sound? If so, what is making this cluck? And how were you thinking of making the Arduino hear? (no build in ears, haha!)
OR
B. Do you want your sound module to replay a cluck sound (and any other speech) and light an LED, in reaction to something? If so, what is that something that would cause your project to "cluck I am a duck" and light up an LED, both attached to your Arduino?
A is hard, B is not too hard. So we need to know what you are up to.

You are a very ambitious and obviously clever 8 year old. Welcome the forum.
Do you have any previous experience with Arduino's, programming, or building things?
Part of your project is deciding what is realistic for you to do, how much help you will need or have available, and how much you want to spend. Remember its your science not your Mom's. 
I think there are three aspects to the project you described.
-
Configuring the duck toy with the light for evil eyes and perhaps the speaker in its chest.
-
recording the message for play back with the ISD 1820 as shown in the video you linked.
-
triggering the playback and evil eyes from the duck.
Using voice recognition to trigger the message and light from the duck is going to be the most difficult part of the project. Some of the voice recognition modules require training to a specific voice and won't work for passing strangers.
I suggest that you think more about your project, and perhaps come up with some other method you might want to use. For example you could have the duck respond to a clap, or if you pat its head, or if you walk close by.
One idea might be for the duck to be friendly saying please shake my wing, and when you did that it gave the evil eyes and some nasty playback.
thank you, ieee488. thank you for the link. this is really helpful. i will need some help making this. I think now I am just copying and learning. it's fine if i am not original. i am just 8.
paul: I don't know.
a7: my mom and i look at it. she said maybe a pre record one like you put inside a stuff animal. i record the sentence and push a button to play?
cattledog: thank you. you have a cool name. i love animals. i have build some stuff like battery wind turbine in a class. i am not good at coding. haha, my mom does not know any coding. i didn't know things can get that hard. i tought its simple. i will think more.
i tought its simple. i will think more.
One way to keep it simple is to work in small steps where you can always stop the science project at an intermediate stage which has some interest, and explain in detail how you are going to complete it. A partial project with a good path forward is better than a complex mess which doesn't work at all.
For example
-
Work on a toy duck with evil eyes. Perhaps have the eyes blink a Morse code message, or use the kind of led which can blink in 3 colors. You could explain about Morse code, and provide a code sheet and ask the other kids to decode the ducks message. Perhaps a push button could get the eyes blinking.
If you have to stop here, explain how you will make the duck speak and respond to a passerby. -
Add the speaker and play back message to the evil duck and have it started by a simple push button. If you have to stop here explain how you plan make the duck respond to a passerby without the button.
-
Get the duck to respond to a passerby with a voice or touch or being close.
Good luck, and keep us informed of what you do.

hi cattledog: thank you. i just learn how to quote people. haha.
i talk to my mom, she said what i want to do can be like in the futre after i do easier ones. i am choosing to do a heart shape led lights:
i am afraid of the hot metal that glue the wires together. can i do it without hot metal it together?
is there a way for the heart shape lights to light up after i play a sound box? i want to push a button on a sound box, it will play my voice saying "i don't like you." and have heart shape lights blink?
thank you.
OK, so you have an relatively easier project.
The “hot metal glue” is called solder, and connecting things with it is called “soldering”.
I have never done a project without needing to solder something along the way. You can do some experimenting without soldering and there may be kits of components made for doing just that.
But anything like a stuffed duck that clucks and flashes an LED will probably need soldering if it is going operate reliably for any length of time.
I learned to solder when I not that much older than you. Look forward to learning this yourself without fear - with care and common sense and good tools, which needn’t be expensive, there’s nothing at all to fear.
Tthere’s no way to know if you are too young just yet for soldering. I don’t know any 8 years old, but when I was 8 kids were, well, different and none of us would have had any business being anywhere near any of the kind of stuff that is just routine these days.

I think that you will be fine with soldering. At eight years old with good eyes and steady hands you will probably do a better job than many of the oldsters on the forum. Having a soldering iron with temperature control will make the job easier.
The project you are looking out uses some special electronics chips to work the lights, and does not actually use an Arduino. It is a hardware project.
If you want to learn about Arduino and software, you might want to consider using one instead of the hardware to work the lights. You could also use a string of lights called neopixels. You may be able to avoid soldering as well if you use them, but it may be a little more expensive.

Is the "sound box" what you showed us earlier which used the Arduino and the voice recording/playback module, or is it some other device which does not require an Arduino? If you want to use the Arduino for your sound playback, then it would also make sense to have it running the lights.
One of the things you are now learning is that planning a project and thinking it through in detail is an important first step.
My granddaughter was just fine with soldering at 8 (now 9).
The thing is, you need the equipment - a proper temperature controlled iron of at least 30 Watts, not some cheap toy to give you trouble.
