Problem: Unable to change the speed of text to speech voice.
ActivePresenter version: ActivePresenter Pro Edition
Version 8.5.7 - 64-bit build. (Released: 2022.05.16)
Notes: The sliders for changing the speed and volume of the text to speech function is greyed out? How can I speed up a voice?

Besides, you can get the support SSML tags from Google Cloud (Speech Synthesis Markup Language (SSML) | Cloud Text-to-Speech Documentation | Google Cloud) and Microsoft Azure (Speech Synthesis Markup Language (SSML) - Speech service - Azure Cognitive Services | Microsoft Docs).
