Text-to-speech
I am using text-to-speech function and amazon polly sucessfully with ActivePresenter 9.2.
Today I wanted to change the voice speed using SSML support.
I tried official Amazon Polly example from here
For certain applications, you may find that you'd prefer the voice you like be slowed down, or speeded up. If the speed of the voice is a concern, Amazon Polly provides the ability to modify this using SSML tags. For example, if your organization was...
It tried this code:
In some cases, it might help your audience to slow
the speaking rate slightly to aid in comprehension.
But when I click on generate ActivePresenter returns a popup window telling me that the SSML code is invalid.
So I tried the code directly with Amazon Polly and there it worked fine.
Is there a know problem with SSML and Amazon Polly and ActivePresenter?

Hi Armin,
According to Amazon Polly documentation , only Standard, Neural and Long-form voices support changing the voice speed:
Prosody tag attributes are fully supported by the standard TTS voices. Neural and long-form voices support the volume
and rate
attributes, but don’t support the pitch
attribute.
