Documentary scripts
Explanatory and historical pieces, the use our note names.

Margaret is a house recipe fixed as one voice: two parts Imogen, our British female voice with a steady pace, to one part Edmund, the low British male of our notes. Our note gives her documentary scripts and chapter introductions. She comes ready to use, and her ingredients are there when you want your own balance.

About this voice
Imogen supplies two thirds and the pronunciation, with a note that says British female, steady pace for courseware. Edmund supplies one third, with a note that says low British male, works for documentary voiceover. The result is a British read that moves at an even pace with a low floor under it.
We kept the recipe because we wanted a British documentary read with more floor than Imogen alone. Both ingredients are British English voices. The accent stays consistent from the first line to the last, and long scripts come back as one continuous file.
Length the engine likes. The published guidance puts the sweet spot at roughly 100 to 200 tokens, a few sentences per line.

For a different balance, blend Imogen and Edmund yourself in the generator's advanced settings.
Blends
Margaret comes mixed at two parts to one. For your own balance, lead with Imogen in the generator and set Edmund's share on the slider, starting at 30 percent.
The larger share sets the British pronunciation and pace. Our note says steady pace for courseware, which keeps a long documentary script moving at an even speed.
2 parts
The smaller share lends the low timbre. Our note calls Edmund a low British male that works for documentary voiceover.
1 part
Margaret comes ready as a house blend. To build your own version, start from one of its single voices.
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
