Short promos
Offers, reminders, and launches in a few sentences, the use our note names.

Piper is graded C- on the published voice list: a B target quality, but under ten minutes of training audio, the smallest band the list marks. Our note gives her short promotional scripts, and she is the smaller part of Tessa, our house blend for promo hooks. No other recipe includes her.

On the record
The list flags the under-ten-minute band with a warning mark, and it pulls the overall grade down to C- despite a B target quality. Four voices we ship sit in that band; Piper is one.
Our note keeps her on short promotional scripts, which fits the guidance that thinly trained voices do best on a few sentences at a time. In Tessa she is one part against two parts of Sienna.
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.

Two parts Sienna and one part Piper is a fixed voice on the roster; try Tessa before blending Piper yourself.
Untested as a second voice outside Tessa; the widget lets you hear her under any primary.
Blends
Tessa is the only kept recipe with Piper, and there she is the second voice. With Piper leading, these are pairings to try.
The reverse of Tessa. Sienna is brighter than Maya by our note and graded A-; listen for whether 70 percent of her lifts Piper's promo read.
70% Sienna
Our note on Delaney is low and throaty; listen for whether half of her gives a promo some edge.
50% Delaney
Walter is our seasonal-announcement pick; listen for announcer weight under a short promo.

Quinn is our product-announcement pick; listen for whether two short-form voices read a notice cleanly together.

FAQ
Training audio. The published list gives her a B target quality but under ten minutes of audio, and small durations lower the overall grade.
Tessa is a fixed house blend, two parts Sienna to one part Piper. Piper alone is the C- voice; Tessa borrows most of its timbre from Sienna.
A few sentences per utterance. The published guidance names very short lines and very long ones as the weak spots.
Yes. Every English voice reports word timing during synthesis, so the SRT cues follow the read.
