How can I insert small pauses to make text-to-speech more lifelike? I have started adding commas (in places that shouldn't have them) to force a tiny pause between words, but I want to be able to pause longer between paragraphs. Also, it would help to have a way to subtly raise the intonation of the stressed syllable at strategic points, for emphasis or in questions. I imagine that the second request could be difficult, but not the first (pauses). Any suggestions?
