[DECtalk] Best way to record sound from a DECtalk Express

[Jayson Smith]

Hi,

Most of what you said is true. However, using a sampling rate above 
11025 won't get you any actual better quality speech. It sounds like it, 
but it's just aliasing. As far as I know, all DECtalk versions generate 
speech at 11025.
