How billing works
How is Text to Speech billed?
Per second of generated audio, at the per-minute rate of the model you use, excluding VAT.
How is Clarity billed?
Per second of input audio, rounded up, with a one second minimum per request. The rate is €0.0015 per minute, excluding VAT. A request that fails with an error is not billed.
Do the prices include VAT?
No, the prices are net. Next to each price you see the amount including 19% German VAT. Consumers in other EU countries pay their local VAT rate, shown before payment.
What do a million characters cost?
It depends on the model: the comparison above lists the price per million characters for each one, assuming about 825 characters per minute of speech. Billing is always by audio duration.
Do EU hosting or voice cloning cost extra?
No. EU hosting, voice cloning, streaming and word-level timestamps are included with every Text to Speech model. Customers in the EU and EEA get the EU Sovereign Cloud at the same rate.
Are there lower rates for high volumes?
Yes, with committed usage on an Enterprise agreement. Talk to us and bring your expected minutes per month.
Can I try it for free?
Yes. Every new account gets €5 of Text to Speech credit once, enough for at least 70 minutes of audio with any model. No credit card is needed, and the credit does not expire.
