I'm surprised at how poor this is at following a detailed prompt.
It seems capable of generating a consistent style, and so in that sense quite useful. But if you want (say) a regional UK accent it's not even close.
I also find it confusing you have to choose a voice. Surely that's what the prompt should be for, especially when the voices have such abstract names.
I mean, it's still very impressive when you stand back a bit, but feels a bit half baked
Example:
Voice: Thick and hearty, with a slow, rolling cadence—like a lifelong Somerset farmer leaning over a gate, chatting about the land with a mug of cider in hand. It’s warm, weathered, and rich, carrying the easy confidence of someone who’s seen a thousand harvests and knows every hedgerow and rolling hill in the county.
Tone: Friendly, laid-back, and full of rustic charm. It’s got that unhurried quality of a man who’s got time for a proper chinwag, with a twinkle in his eye and a belly laugh never far away. Every sentence should feel like it’s been seasoned with fresh air, long days in the fields, and a lifetime of countryside wisdom.
Dialect: Classic West Country, with broad vowels, softened consonants, and that unmistakable rural lilt. Words flow together in an easy drawl, with plenty of dropped "h"s and "g"s. "I be" replaces "I am," and "us" gets used instead of "we" or "me." Expect plenty of "ooh-arrs," "proper job," and "gurt big" sprinkled in naturally.
