A Professional Audiobook Publishing Agency Connecting Authors to Listeners on Every Major Platform
Spark Leaf Publishing is an audiobook publishing company that helps authors turn finished manuscripts into studio-grade audiobooks, narrated, mastered, and distributed for listeners across the USA and worldwide.
Every audiobook begins with a finished manuscript waiting to be heard.

Our production team follows current ACX and retailer technical standards, so each audiobook moves through platform review with fewer revisions and reaches listeners faster. We also prepare accurate, search-ready metadata, so your title is easier for listeners to find once it goes live.
From your first idea to your first sale, we're with you every step of the way.
Every genre has its own pacing, tone, and listener expectations, and our professional narration services adapt to match them. A business audiobook needs clarity and authority. A thriller needs tension and timing. A children's audiobook needs warmth and rhythm.
As an experienced audiobook publishing company, our team has produced fiction audiobook production and non-fiction audiobook production across the categories listeners search for most, with every production decision made around how that genre is actually consumed.
Let's turn your manuscript into a professionally produced audiobook that listeners can find, trust, and enjoy.
As an audiobook publishing company, we manage your project from manuscript review through narration, editing, mastering, and distribution. Our team handles voice casting, studio recording services, and platform submission so your file meets retailer standards before it goes live.
You can request a free quote or schedule an online consultation. We review your manuscript, discuss narration style and budget, and outline a clear, affordable production timeline before recording begins.
You retain ownership of your audiobook rights. We help you understand platform-specific royalty structures, such as ACX exclusive and non-exclusive distribution terms, so you can choose the option that fits your publishing goals.
Our audiobook production and publishing services require a completed, edited manuscript or eBook file. If your manuscript still needs editing, we recommend finishing that step first so the narration script reflects your final content.
