Questions about billing and usage
How is usage counted?
By characters of text sent for speech. Spaces count, SSML tags do not.
What happens when I reach my limit?
We email you at 80% and 100%. Requests keep working for a short grace period so nothing breaks mid-sentence.
Can I change plans at any time?
Yes. Upgrades apply immediately. Downgrades apply at the start of your next billing period.
Do unused characters roll over?
On paid plans, up to one month of unused characters rolls over to the next period.
