Composite Synthesis

Composite synthesis lets one chapter use more than one engine or voice, stitched into a single, seamless result.

At a glance
  • Mix engines/voices within one chapter.
  • Studio stitches the output together.
  • Formerly called “mixed” synthesis.

When chapters mix engines

Sometimes the best cast spans engines. A narrator on the local engine and a specific character on another, for instance. Composite synthesis handles that within a single chapter.

How composite rendering stitches output

Each segment is rendered by its assigned engine/voice, then combined in order. Because completion is tracked per validated artifact, segments from different engines assemble cleanly into one chapter.

Note: Composite was previously called “mixed” synthesis; you may still see that term in older material.
