Pricing
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Description | Cost/month | Overage cost |

Dimensions summary
This listing offers one pricing dimension: the L base plan, sold as Units of credit under a contract. You buy the plan's base credit allotment, and those credits fund your usage of the voice AI models. Credits convert into usage by activity type, so the same credit balance covers different services at different rates. Text-to-speech draws credits per character, while speech-to-text and translation services draw credits per second at their own rates. Your billing is a single committed credit amount rather than separate charges per service.
Top-of-mind questions for buyers
Credits convert by activity type. Text-to-speech draws 1 credit per character, where about 45,000 characters equals one hour of audio. Speech-to-text draws 3 credits per second. Speech-to-text translation draws 4 credits per second. Speech-to-speech translation draws 30 credits per second. Each service consumes your shared credit balance at its own rate.
Speech-to-speech translation consumes credits fastest at 30 credits per second, roughly 100,000 credits per hour. Speech-to-text translation uses 4 credits per second, and speech-to-text uses 3 credits per second. Text-to-speech uses 1 credit per character. All services draw from the same credit balance, so your mix of activities drives depletion.
The pricing table sets a base credit amount for the L plan under a contract. The vendor's public materials list this scenario in their FAQ but do not state the outcome in the crawled content. Contact the vendor to confirm how additional usage beyond your credit balance is handled.
