Asking for 20second of pause in text->speech gives only 5s and 10s for this code:
I would expect 20s!

    Hi, according to the documentation, the time value should be set less than 5,000 ms. Hope this helps.

    As you can see in my 2nd comment, 4x5000ms != 20sec but 10,71sec, which makes it useless.
