I suspect that any real-style SAPI 5 voice you will have a delay. There is a whole lot of processing going on. If you are moving through standard folder lists, etc. I recommend Eloquence as your default voice and use SAPI 5 only for Say All Voice. Then you can use SAPI 5 by pressing Ins-Down Arrow, or switch to Eloquence with Alt-Ins-Down Arrow for reading large documents. SAPI 5 is just too slow when doing normal Windows operations.

I use sapi 5 as my default synthesizer. I use either Samantha, or a t n t crystal Whay lag a few seconds but for the most part they are ok. but I want to by some of the kepstral voices. but I need to know if that are like this example, when you have toe toter and message voice on and jaws says folder list view, to move throw the items use the aero keys. between those sentences, is there a huge delay? with the okapella heather voice that my coleeg uses, there is a big delay. I am wondering if that delay is noticeable with sepstral. Thanks I want to know before I spend more money. Alex.
