Real-World: Voice-activated home devices, voice-driven manufacturing systems, healthcare
assistive robots.
AI TOOLS FOR SPEECH RECOGNITION
Offline Modules: Some microcontrollers or shields can detect limited voice commands
(keyword spotting).
Online/PC-Based: Services like Pictoblox (with speech extensions), or custom solutions using
Python speech libraries. The heavy processing is done off-board, sending recognized text to
the Arduino.
SPEECH BASED HOME AUTOMATION ACTIVITY
To get deep knowledge of Speech Recognition AI, scan the code and try building this small activity.
IMPORTANCE AND APPLICATIONS OF SPEECH RECOGNITION AI
Speech Recognition AI is widely used in:
Smart Assistants (Alexa, Siri, Google Assistant).
Voice-Controlled Home Automation (Turning lights ON/
OFF).
Accessibility (Helping individuals with disabilities control
devices).
INTERFACING SERVO MOTORS WITH ARDUINO
HOW SERVO MOTORS WORK
Definition: Small motors with an internal feedback mechanism that allows precise angular
control (0° to ~180°).
Signal: Requires a PWM-like control pulse on the signal wire to position the servo arm at a
specific angle.
Applications: Robotics arms, RC vehicles, animatronics (like expressive faces).
