1
Find Your Voice Recorder
3 minutes — Setup
On a phone or tablet:
Look for an app called "Voice Memos," "Recorder," "Voice Recorder," or similar
It's usually pre-installed (look in your utilities or tools folder)
Open it and test that it works by saying "Testing, one, two, three" and playing it back
Make sure the volume is loud enough to hear clearly
On a computer:
Windows: Search for "Voice Recorder" in the start menu
Mac: Search for "Voice Memos" in Spotlight
Or use a free recording website (your parent can help find one)
Test it before you start! Record and play back: "This is my practice recording" to make sure it's working well.
2
Choose Your Test Sentence
2 minutes — Preparation
Pick ONE sentence you'll say in different moods:
Easy option: "I'm going to school today"
Other good options:
"That was really interesting"
"I had a good day"
"I'm thinking about it"
Or create your own! Just make sure it's:
Neutral (not already happy or sad)
Easy to say clearly
Something you could say in lots of different moods
Not too long (one sentence works best)
3
Record Your Mood Collection
10 minutes — Performance!
You're going to record the SAME sentence in 5 different moods. Echo will learn how YOUR voice changes with emotion!
Before each recording:
Take a deep breath
Really FEEL the mood (think of a specific memory that creates that emotion)
Let it show in your voice naturally—don't fake it!
Acting Tips: If you're having trouble feeling the mood, think of a specific memory that creates that emotion. Happy = your last birthday party, getting a gift you wanted. Tired = waking up too early on a Monday. Nervous = before speaking in front of the class. Grumpy = when someone woke you up from a good nap. Calm = reading your favorite book, petting your dog. Real memories create authentic voice patterns!
Recording 1: HAPPY / EXCITED
Think about something that makes you really happy
Smile while you talk! (Smiling changes your voice even when people can't see you)
Hit record and say your sentence with excitement
Hit stop
Label it: "Mood 1 — Happy"
Recording 2: TIRED / BORED
Think about how you feel at the end of a really long day
Let your energy drop, maybe even yawn first
Record your sentence slowly and tiredly
Label it: "Mood 2 — Tired"
Recording 3: NERVOUS / WORRIED
Think about before a big test or presentation
Let your voice sound a little uncertain, maybe faster
Record your sentence with that worried energy
Label it: "Mood 3 — Nervous"
Recording 4: GRUMPY / FRUSTRATED
Think about how you feel when things aren't going right
Let some frustration into your voice (no yelling—just annoyed)
Record your sentence with that grumpy tone
Label it: "Mood 4 — Grumpy"
Recording 5: CALM / PEACEFUL
Think about a relaxing moment, maybe before bed
Speak gently and calmly, no rush
Record your sentence with that peaceful energy
Label it: "Mood 5 — Calm"

Listen and Analyze
5 minutes — Detective Work
Play back all 5 recordings in order. Notice the differences and write them down:
SPEED CHANGES:
Which moods make you talk faster? (Probably happy or nervous)
Which make you talk slower? (Probably tired or calm)
Where do you pause differently?
PITCH CHANGES:
Does your voice go higher when excited?
Does it go lower when grumpy or tired?
Does it crack or waver when nervous?
ENERGY CHANGES:
Can you HEAR the energy level changing?
Which recordings sound like you have lots of energy?
Which sound like you're running out of battery?
TONE QUALITY:
What makes "grumpy" sound different from "calm" even though both are lower energy?
How does "happy" differ from "nervous" even though both are energetic?
Can you hear emotion beyond just pitch and speed?

Compare and Contrast
3 minutes — Pattern Spotting
Look at your notes. What are YOUR unique voice patterns?
Everyone's voice changes differently with emotion. What's YOUR signature?
Do you get MUCH faster when excited, or just slightly?
Does your pitch change dramatically or subtly?
Do you pause a lot when nervous, or rush through?
What's the BIGGEST difference between your happy voice and sad voice?
6
Test Echo's Understanding
3 minutes — Optional
If you have a voice assistant (Siri, Alexa, Google Assistant):
Try asking it questions in different moods and see if it responds differently:
Ask "How are you?" in a happy voice
Ask "How are you?" in a sad voice
Does Echo's response change?
Or test this way:
Use voice-to-text in different moods
Does your excited voice make more typos?
Does your tired voice get misunderstood more?
Does nervous-fast speech confuse the AI?
Most current voice assistants DON'T change responses based on mood yet—but noticing this helps kids understand what Echo COULD learn to do in the future. What they're discovering is that current AI often ignores emotion, but their training helps them see what's possible.
You've Succeeded When:
You can clearly hear differences in your voice across the 5 moods
You've identified specific patterns in YOUR voice that signal different emotions
You understand that voice carries information beyond just words
You've thought about how AI could learn to recognize YOUR specific emotional patterns
You realize how much you communicate through HOW you speak, not just WHAT you say
You've documented your personal voice patterns for future reference
If Something Goes Wrong
"All my recordings sound the same to me."
You're probably more expressive than you think! Ask a parent or friend to listen to two of your recordings without telling them which emotions they are. Can THEY tell the difference? If yes, then the patterns exist—you just need to identify them more specifically. If no, try MORE extreme emotions (super excited vs. totally exhausted) to create clearer differences. Or record on a better device—phone microphones sometimes don't capture subtle vocal changes well.
"I feel weird recording myself with different emotions."
Totally normal! Most people feel self-conscious at first. Here's the trick: Don't just "perform" the emotions—actually THINK about something that makes you feel that way, THEN record. Real emotions create authentic vocal patterns. If you're faking it, even you won't hear the difference, and neither will Echo. Also, remember this is private—you don't have to share these recordings with anyone!
"My happy voice and my excited voice sound exactly the same."
That's fair—those emotions ARE similar! The difference might be subtle. Happy is often more steady and warm, while excited is more energetic and higher-pitched. Happy is contentment, excited is anticipation. But if they're really similar in YOUR voice, that's fine! That's YOUR pattern. Just note: "My happy and excited voices are similar—both higher and faster than my baseline."
"I can't make my voice sound [emotion]."
Some people have less vocal variation than others, and that's okay! Your patterns might be more subtle—maybe you change speed more than pitch, or pause patterns more than volume. Or maybe your voice stays pretty consistent and you express emotion through other channels (facial expressions, body language, word choice). That's valuable data too! It means Echo would need to learn to read YOUR specific (subtle) cues, not generic emotional patterns.
Talk About It
For Kids
What surprised you most about how your voice changes with emotions?
Did you notice patterns you weren't consciously aware of before?
How much information do you think we communicate through tone vs. actual words?
If Echo could learn to read YOUR voice perfectly, what could that help with?
Do you change your voice intentionally sometimes, or does it just happen automatically?
For Parents
Did your child demonstrate self-awareness about their communication patterns?
How might this awareness help them communicate more effectively with others (not just AI)?
Did they understand that AI needs explicit teaching about things humans do naturally?
Could this exercise help them recognize when others' tone doesn't match their words?
"I'm learning to hear not just your WORDS, but your FEELINGS. But I need you to teach me what YOUR specific voice patterns mean!"
