I find the text-to-speach function very useful. Unfortunately, the quality of the exported files is rather low (8KHz, 32Kbps only) so the narrations sound very compressed and "robotic".
Is there any way to change the settings to obtain a higher quality audio file?
Also, what is the way to force the tool to create longer pauses between sentences to delimitate eg. a paragraph? I've tried adding extra punctuation, multiple break lines, etc. but the pause between sentences is always the same.
Glad you're liking the TTS feature, and I'd love to address your questions around it!
Our team is brainstorming ways we can further enhance this feature and are tracking requests for more various functionalities. I'll document your thoughts and let you know of any changes! For now, we have these approaches to ensure high-quality media in this article.
If you need longer pauses, one idea is to convert the Text-to-Speech and then open the clip in the built-in Audio Editor to insert silence where necessary. For more top tips for using Text-to-Speech (TTS) in Storyline 360, check out this helpful resource!
Although Storyline doesn’t support Neural voices inside of Storyline yet (which are higher quality voices by Amazon Polly which is used by Storyline), I have created an application that can help streamline the process:
