One hundred and forty six voices
Young is the larger of the two age groups, covering 63 percent of the catalog and spanning every accent and all twelve recommended languages. Unlike most attributes on these pages, age is a genuine tagged field rather than an inference, so this list is filtered rather than judged.
Where younger voices fit
Social media and gaming are the usual contexts. Four voices carry the social media tag and fourteen the character tag, and there is meaningful overlap with the young group. For gaming specifically, WebSocket streaming allows dialogue to be generated during play rather than pre-rendered.
Age is not adjustable
There is no age parameter, so a voice cannot be made to sound younger after generation. This is a casting decision. Given the size of the group, the practical approach is to narrow by accent and language first, then audition within what remains.
A caveat on tagging
The underlying data used several spellings for this attribute, including young, Young and young adult, which have been normalised into one value here. If you query the API directly rather than using this catalog, expect to handle that variation yourself.

Young Voices
Mature Voices
Eighty six voices are tagged mature, and twenty also carry the narrative tag. That overlap is the usual starting point for audiobooks and documentary work, where consistency shows over hours rather than seconds.
Energetic Voices
Speed is the reliable lever here, not casting. Settings between 1.2 and 1.4 lift almost any voice in the catalog, though longer sentences start to blur past roughly 1.5.
Cheerful Voices
Only six voices in the catalog show cheerful or positive markers, the thinnest tone signal available. Speed slightly above 1.0 lifts almost any voice, which is the more dependable route.
Female Voices
One hundred and one female voices, spanning six accent groups and all twelve recommended languages. At that scale accent and language usually constrain casting more than gender does.

Short form rewards pace, and speed adjusts up to 2.0. Scripts change after the edit, so generating line by line means retiming a section costs one line rather than the whole track.

Pre-rendering every branch means shipping every branch. WebSocket streaming lets dialogue generate during play instead, so a conversation tree costs what players actually hear rather than what they might.
