🔊 Machines That Hear · Day 6

Text to Talk

Yesterday you turned your voice into text. Today, the reverse magic: type anything and the AI says it out loud — in different voices, speeds, and pitches. This is how Siri and Alexa talk, running right on your device.

🔊 Step 1 · Type & Speak

Type it — hear it

Type anything in the box and press Speak. The AI reads it out loud using a voice built into your device. Try your name, a joke, or a secret message!

🎛️ Step 2 · Design the Voice

Change how it sounds

Same words, totally different voice. Drag the sliders and pick a voice, then press Speak again. Make it a tiny chipmunk, a giant monster, a sleepy sloth, or a hyper robot!

speed (slow → fast)

1.0

pitch (deep → squeaky)

✨ Quick characters — tap one, then Speak:

🎛️ Try it: set the pitch super high + speed fast = chipmunk. Low pitch + slow = monster. Same words, new character!
⁉️ Step 3 · Punctuation Power

Commas, periods & question marks matter

The AI doesn't just read letters — punctuation tells it when to pause, stop, and change its tune. Tap each and press Speak to hear the difference!

Whoa: "Let's eat grandma" vs "Let's eat, grandma" — one comma saves grandma! 😄 Punctuation is part of how AI understands and speaks.

Give your AI its own voice

Pick a voice, tune the speed and pitch until it sounds awesome, name your robot, and make it introduce itself!

Uses your current voice, speed & pitch settings from above.
