 ## Pricing
 
-- When utilizing the text-to-speech avatar feature, charges will be incurred based on the minutes of video output. However, with the real-time avatar, charges are based on the minutes of avatar activation, irrespective of whether the avatar is actively speaking or remaining silent. To optimize costs for real-time avatar usage, refer to the provided tips in the [sample code](https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/js/browser/avatar#chat-sample) (search "Use Local Video for Idle").
 - Throughout an avatar real-time session or batch content creation, the text-to-speech, speech-to-text, Azure OpenAI, or other Azure services are charged separately.

 Custom neural voice (CNV) endpoint hosting is measured by the actual time (hour). The hosting time (hours) for each endpoint is calculated at 00:00 UTC every day for the previous 24 hours. For example, if the endpoint has been active for 24 hours on day one, it's billed for 24 hours at 00:00 UTC the second day. If the endpoint is newly created or suspended during the day, it's billed for its accumulated running time until 00:00 UTC the second day. If the endpoint isn't currently hosted, it isn't billed. In addition to the daily calculation at 00:00 UTC each day, the billing is also triggered immediately when an endpoint is deleted or suspended. For example, for an endpoint created at 08:00 UTC on December 1, the hosting hour will be calculated to 16 hours at 00:00 UTC on December 2 and 24 hours at 00:00 UTC on December 3. If the user suspends hosting the endpoint at 16:30 UTC on December 3, the duration (16.5 hours) from 00:00 to 16:30 UTC on December 3 will be calculated for billing.
 
+### Personal voice
+
+When you use the personal voice feature, you're billed for both profile storage and synthesis.
+
+*  **Profile storage**: After a personal voice profile is created, it will be billed until it is removed from the system. The billing unit is per voice per day. If voice storage lasts for a period of less than 24 hours, it will be billed as one full day.
+*  **Synthesis**: Billed per character. For details on billable characters, see the above [billable characters](#billable-characters).

+### Text to speech avatar
+
+When using the text-to-speech avatar feature, charges will be incurred based on the length of video output and will be billed per second. However, for the real-time avatar, charges are based on the time when the avatar is active, regardless of whether it is speaking or remaining silent, and will also be billed per second. To optimize costs for real-time avatar usage, refer to the tips provided in the [sample code](https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/js/browser/avatar#chat-sample) (search "Use Local Video for Idle"). Avatar hosting is billed per second per endpoint. You can suspend your endpoint to save costs. If you want to suspend your endpoint, you can delete it directly. To use it again, simply redeploy the endpoint.
