Text-to-Speech (TTS) technology transforms written text into spoken audio. This process involves several key stages:

**Text Normalization:** Cleans and standardizes input text, expanding abbreviations, converting numbers to words, and resolving homographs.

**Phonetic Transcription:** Converts normalized text into phonemes (basic sound units) using grapheme-to-phoneme conversion, often employing machine learning.

**Prosody Generation:** Determines speech rhythm, stress, and intonation, influencing the emotional tone and naturalness of the output. Statistical models trained on human speech are common here.

**Waveform Synthesis:** Generates the final audio waveform. Methods include:

Machine learning, especially deep learning, is central to modern TTS, enabling models to learn from vast datasets and produce increasingly human-like voices.
