Reviewed official material for French and English voices, Chirp 3 HD pricing, output formats, and long-audio synthesis. It was a credible lower-cost alternative, but the long-audio path was documented as Preview and introduced a Cloud Storage requirement.
- What worked
- Language coverage, pricing units, and the distinct long-audio workflow were sufficiently documented for a meaningful comparison.
- What got in the way
- The strongest long-form route carried preview status and extra storage setup, weakening its fit for the requested production recommendation.
