Can I use the generated voice commercially?

Yes. All paid Listnr plans (Individual, Solo, and Agency) include commercial rights for the audio you generate, including monetized YouTube videos, ads, audiobooks, and presentations.

What happens when I run out of my monthly quota?

If you run out of credits, you cannot generate new audio until the quota resets at the next billing cycle. You can purchase extra credits in Listnr Studio or upgrade to a higher plan to continue immediately.

What is the difference between monthly and yearly billing?

Yearly billing charges 10 months up front — two months free compared with paying month to month. Monthly billing renews each month at the listed rate.

Can I clone my own voice with Listnr?

Yes. Listnr supports voice cloning for voices you own or have permission to use, helping teams and creators keep narration consistent without rerecording every update.

How does the text-to-speech API work?

The official API uses requests authenticated with an `x-listnr-token` header. You must keep API keys server-side and confirm your account's access and usage limits before generating audio.

What are the differences between the Listnr Studio API and the TTS API?

They are separate interfaces. The TTS API handles audio generation. The Studio API (with its own OpenAPI spec) provides tools for catalog, pricing, and documentation lookup, but not direct video generation.
