by OpenAI
The same six OpenAI voices at higher fidelity — for the final cut.
OpenAI TTS HD renders the same six voices as the Standard model at higher audio fidelity: cleaner sibilants, less artefacting, more consistent pacing. It costs twice as much per character, which on a typical 60-second script is still only a few cents.
Draft on Standard to settle the script and the voice, then re-render on HD for the version that ships in your ad or product page.

No. Every Zalify workspace with usage balance can generate with OpenAI TTS HD in Z1 Canvas. Paid plans include a monthly usage allowance; you can also add balance at any time, and purchased balance never expires.
Yes. The generate button in Z1 Canvas shows an estimate for the exact model, resolution and length you selected — for example "Generate video · est. $0.24" — before you commit.
No. You are only charged for renders the provider actually completes. If a generation errors out, nothing is deducted from your balance.
Every model in Z1 Canvas is priced on the same USD basis, so you can compare directly on the AI models overview. Cheaper tiers are ideal for iterating on a concept; switch to the model or resolution you want for the final render.
