Tts D4pci Quality Question

[vroberts2]

I'm using ATT natural voice with D4PCI. I've read all the quality posts on the forum, but wandered if there is another card that would give better quality. Such as switching to ISDN PRI/BRI card & line vs. analog.

 

Just curious to see if this is as good as it gets or if a higher quality line/card combo would drastically improve quality.

 

Thanks

ISDN connections result in slightly better sound quality.

 

The TTS however will not sound much better on Digital vs Analog.
