SPEECH RECOGNITION AI                                                                    CHAPTER

                   By the end of this lesson, students will:
                       Understand the fundamentals of Speech Recognition AI and its real-world applications.
                       Learn how to interface servo motors with Arduino to create mechanical expressions.
                       Program and integrate AI-based speech commands to control emoji facial movements.
                       Build a Voice-Controlled Emoji Project that responds in real time to spoken words.




                 So far, you’ve used artificial intelligence to let your Arduino sense facial expressions. But another
                 major channel of human interaction is speech. By integrating speech recognition AI with servo
                 motors, you can create a robot that listens to your words and reacts by moving mechanical
                 features—like an “emoji face” that changes its expression. In this lesson, you’ll learn how to capture
                 voice commands, recognize them using external AI tools, and translate those commands into
                 servo-driven expressions on a playful emoji.




                           FUNDAMENTALS OF SPEECH RECOGNITION AI


                 WHAT IS SPEECH RECOGNITION?
                     Definition: Converting spoken language into text or commands that

                     a machine can interpret.
                     Common Uses: Virtual assistants (Siri, Alexa), automated customer

                     service, voice-to-text apps.



                           WHY USE SPEECH IN ROBOTICS?

                     Hands-Free Control: Perfect for situations where pressing buttons
                     is inconvenient.

                     Intuitive Interaction: People naturally use speech to communicate,
                     making robots feel more accessible.
