Who Uses Musely Text to Speech for Audiobooks
First Audiobook Production
Musely let me create the audiobook version of my debut novel without any recording equipment. The voice stayed consistent from Chapter 1 through Chapter 22, and I published on ACX within two weeks. Total cost: zero dollars.
Catalog Audiobook Conversion
We converted 35 backlist titles to audiobooks with Musely in eight weeks. At $4,000 per title for human narrators, this saved us $140,000. Revenue from the audiobook editions exceeded our quarterly projection by 89%.
Textbook Audio Companions
I created audio versions of my 400-page textbook using Musely. Students with visual impairments and those who prefer audio learning now have equal access. The calm emotion mode fits academic content perfectly.
Audiobook Production at Scale
Our startup produces audiobooks for indie authors. Musely handles narration and we handle distribution. We onboarded 47 authors in our first quarter because Musely dropped production costs by 91%.
Translated Work Audio Versions
After translating novels into English, I use Musely to immediately create audiobook versions. The expressive narrator voices capture the tone of translated prose, and publishers appreciate getting both formats simultaneously.
Library Audio Collection Expansion
Musely helps our library create audio versions of public domain titles. We expanded our digital audio collection by 120 titles in three months, dramatically improving accessibility for our community.
