Book excerpts
Chapter openings and readings, the use our note names.

Rosalind grades C on the published list: B target quality, 10 to 100 minutes of audio, second among the British female voices behind Imogen. Our note gives her chapter introductions and book excerpts. No recipe we kept includes her, so the pairings below are ones to try.

On the record
B-quality audio in the minutes band yields a C, one step above the D that Freya and Nell carry and one below Imogen's B-. The published list grades data, and says so.
Our note is about books: introductions and excerpts, which means measured prose and proper names. The first sample is the closest match, so start there.
Length the engine likes. The published guidance puts the sweet spot at roughly 100 to 200 tokens, a few sentences; very short lines are the weak spot and very long ones can rush.

Both British, one grade apart. Play the first samples side by side.
Blends
None of these is a recipe we kept. Rosalind keeps the British pronunciation; the second voice lends its timbre.
Our note on Edmund is a low British male for documentary voiceover; listen for a lower floor on a chapter opening.
50% Edmund
Imogen is our top-graded British voice; listen for whether 60 percent of her steadies a long excerpt.
60% Imogen
Our note on Delaney is low and throaty; listen for whether half of her warms a reading.
50% Delaney
Rory is our British story pick at the same C; listen for a two-voice story timbre.

Every blend works the same way: the first voice sets the pronunciation and pacing, the second voice lends only its timbre, and you choose the ratio between 10 and 90 percent. See the three steps on the voice library page
