If you want to operate PSK or AFSK RTTY,  you  can have the screen reader on 
one card and  the digital software  on the other.    Using only 1 card you 
have to be careful that  the screen reader voice doesn't go out over the 
digital  output.    With 1 sound card, you can limit  how much the screen 
reader speaks to avoid this problem or use something like Digitalk for PSK 
which is self voicing.   I run RTTY in FSK mode which doesn't use the 
soundcard for TX and so no problem.
