The Voice-First Writing Workflow

Many writers find that speaking their ideas is faster than typing. Here's a modern workflow:

1. Speak your ideas using Sonicribe (offline transcription)

2. Expand the transcript with Claude or ChatGPT

3. Refine with AI for structure and clarity

4. Edit as a human for final polish

This approach captures your authentic voice (literally) while using AI to expand and refine. The result often feels more natural than pure AI generation.

Tips for Better AI Writing

1. Start with Your Voice

Don't ask AI to write from nothing. Give it your notes, transcripts, or rough thoughts. Tools like Sonicribe can capture your spoken ideas as starting material.

2. Be Specific About Tone

Instead of: "Write a blog post about productivity"

Try: "Write a blog post about productivity for busy executives, conversational tone, actionable tips, 1200 words"

3. Iterate, Don't Accept

First drafts need work. Ask for alternatives, refinements, or different approaches.

4. Provide Examples

Show the AI content you like. "Write in this style" with an example works better than describing the style.

5. Edit as a Human

AI gets you 80% of the way. Your job is the final 20%—the polish that makes it authentically yours.

AI Writing Ethics

Some considerations:

• Disclosure: Consider when AI assistance should be disclosed
• Plagiarism: AI can inadvertently reproduce training data
• Accuracy: Verify facts, especially for technical content
• Authenticity: Maintain your genuine voice and perspective
• SEO: Search engines increasingly detect AI content

The best approach: use AI as a collaborator, not a replacement. Your ideas, your expertise, AI's help with words.
