    7. Focus AI Concept:

      8. 👉🏿 Explain that Text-to-Speech (TTS) is an AI technology that analyzes written text and converts it into spoken audio.

      👉🏿 Discuss how AI models are trained on large amounts of human speech data to generate natural-sounding voices with different accents, languages, and speaking styles.

      👉🏿 Encourage students to compare AI-generated speech with human speech and evaluate the strengths, limitations, and real-world applications of TTS systems.
