About this voice
A bright voice for the first three seconds
Our note places her next to Maya as the brighter of the two. That brightness suits an opening line, a launch or a sale, where the first word has to land.
Promo hook, the recipe we kept, blends her at an even split with Brooke. Write the hook as its own line, add a pause tag before the offer and keep it to a sentence or two.
Length the engine likes. The published guidance puts the sweet spot at roughly 100 to 200 tokens, a few sentences per line.

FAQ
Questions about Sienna
How do Sienna and Maya differ?
Both are American English voices. Our note calls Sienna the brighter of the two, good for hooks and short promos. Maya is warm and even for long reads.
What speed should I use for a TikTok hook?
Start at 1.0 and listen. A tight hook of one or two sentences lands harder than a faster setting, so trim the line before you touch the slider.
Can I use Sienna as a second voice?
Yes. The primary keeps its pronunciation and Sienna lends only her timbre. The widget below lets you try any share from 10 to 90 percent.
Does Sienna return timed captions?
Yes. Every English voice reports word timing during synthesis, so the SRT and VTT files follow the read word by word.
