Is there a control sequence that I could insert into the text that would cause the audio to pause?
ActivePresenter supports SSML 1.0 (https://en.wikipedia.org/wiki/Speech_Synthesis_Markup_Language), so you can use it for advanced control of the voice.
For pausing, you can use the
<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.w3.org/2001/10/synthesis http://www.w3.org/TR/speech-synthesis/synthesis.xsd" xml:lang="en-US"> Take a deep breath <break/> then continue. Press 1 or wait for the tone. <break time="5s"/> I didn't hear you! <break strength="weak"/> Please repeat. </speak>
Please note that if you use SSML then you need to enter the full
<speak> root tag into the Text field when generating audio.
