Challenge

Despite her deep expertise and growing visibility, Rosa faced two major bottlenecks:

• Time scarcity: With a full-time role in healthcare, she had little bandwidth to sit down and write.

• Message bottleneck: Ideas were flowing, but turning them into structured, shareable content felt overwhelming. Traditional writing felt unnatural. And previous tools like voice memos lacked structure, making it hard to organize or repurpose insights.

“I wouldn’t consider writing a book, if we hadn’t had this efficiency in place.”

Solution: Carbon Voice 

Rosa partnered with Simi Burn using Carbon Voice and used a simple but powerful process:

• Voice-first workflow: Rosa recorded 20-minute voice notes during her commute—time she’d normally spend listening to podcasts.

• Smart summarization: Carbon Voice turned her raw voice notes into clear, organized summaries—automatically categorized by theme or chapter.

• Collaborative refinement: She could easily add new thoughts to specific chapters and share them with her collaborator Simi, by simply speaking them aloud and letting the system organize it.

The results? What started as spontaneous voice reflections became the foundation for a book and a structured podcast pipeline.

Results

✅ 4 hours of audio became a complete book manuscript

✅ Saved time by leveraging unused commute hours

✅ Avoided writer’s block and perfection paralysis

✅ Streamlined podcast ideation and expert interviews

✅ Communicated more clearly with collaborators using voice tone + AI summaries

“I just wouldn’t do it otherwise. Carbon Voice didn’t cut into my workday—it made my voice actionable.”

Reflection: “Carbon Voice became the bridge between my voice and my vision. I finally had a scalable way to share my story and amplify others—without needing to write a single sentence from scratch.”
