Remarks

This class handles text normalization and grapheme-to-phoneme (G2P) conversion to prepare text for acoustic model input.

For Beginners: Before TTS can synthesize speech, we need to convert written text into phonemes (speech sounds). This involves:

• Normalizing text (expanding abbreviations, numbers)
• Converting graphemes (letters) to phonemes (sounds)

For example: "Dr. Smith, 123 Main St." becomes phonemes like "D AH K T ER S M IH TH..."
