Understanding AI Text-to-Speech

How Text-to-Speech Works

1. Text Input: You provide written content to be spoken
2. Voice Selection: Choose from available voice options
3. Processing: AI analyzes text and applies natural speech patterns
4. Audio Generation: Creates final audio file with human-like speech

Key Audio Elements

Writing Text for Optimal Speech

Text Preparation Fundamentals

1. Write for the Ear, Not the Eye

• Use conversational language instead of formal writing
• Choose simple sentence structures for better flow
• Include contractions (don't, can't, won't) for natural speech
• Avoid complex punctuation that doesn't translate to speech

2. Consider Pronunciation

• Spell out abbreviations: "Doctor" instead of "Dr."
• Write numbers as words: "Twenty-five" instead of "25"
• Use phonetic spelling for difficult names or terms
• Avoid acronyms unless they're commonly spoken as words

3. Structure for Speech Flow

• Use shorter paragraphs to create natural breaks
• Include transition words to connect ideas smoothly
• Add emphasis markers where important (bold, italics)
• Plan for natural pauses with punctuation
