checking their code and sensor settings. This hands-on experience boosts their understanding of
programming and sensors, while also developing their critical thinking and problem-solving skills!

Applications

You can make computer games that use gestures! Wave your hand to make your character run, and
give a thumbs-up to jump!

Voice Control System

Voice recognition technology is a fascinating part of artificial intelligence (AI) that allows machines
to understand and respond to spoken commands. This technology is used in various devices, from
smartphones to smart speakers. As you explore how voice recognition works, think about how
creativity can enhance its development and functionality!

How Voice Recognition Works

Sound Waves: When you speak, your voice creates sound waves that travel through the air.

Microphone: A device (like a smartphone or smart speaker) has a microphone that picks up these
sound waves and converts them into digital signals.
Processing: The digital signals are then processed by AI algorithms that analyze the sounds to
identify words and phrases.

Response: Once the AI understands your command, it can perform an action, such as playing
music, setting reminders, or answering questions.
