Callum, British English male, our documentary-summary pick
Callum is graded D+ on the published voice list: a C target quality, but 1 to 10 hours of training audio, more than any other British male. Our note gives him documentary summaries. No recipe we kept includes him, so the pairings below are ones to try in the widget.

Three samples, three registers
- A documentary-style line; listen for the pace over the long clause.
- Listen for how a summary voice handles a sales line.
- Listen for whether he narrates it plainly.
On the record
A D+ from one to ten hours of audio
The D+ is an unusual record: more audio than Rory or Edmund, but at C quality rather than B. The published list weighs both, which is why an hour or more of weaker audio lands one step above D.
Our note keeps him on documentary summaries, the wrap-up rather than the opening. Edmund's note covers the low documentary read; Callum is the alternative with more, but rougher, data.
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.
