[Doc]: TTS batch synthesis maximum JSON payload size

[firmart]

• In the Batch synthesis API for text to speech page, it is written

  The maximum JSON payload size that will be accepted is 2 megabytes.

• In the Batch synthesis properties for text to speech page, the description of the inputs property said :

  There are no paragraph limits, but the maximum JSON payload size (including all text inputs and other properties) is 500 kilobytes.

Which one is correct ?

Thanks.
