                  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).
