there is no real way to make the screen reader wait, or to know when it is done speaking. hat GMA games does is a function called speech delay. Since everyone uses their screen reader at a different speed you can't give it a fixed value. GMA has a speech delay calculator that sends a string of text to the screen reader. Once the text is done, the user presses enter, and the speech delay is calculated. It's not perfect ,but it's a lot better than nothing. ANd I'm not sure about how it calculates how long strings are so it can give the reader more or less delay. Perhaps it does a word count and figures out how many words per second it reads and then uses a proportion for each sentence sent. Try it out.
