</div>The synthesis via the swift command is much faster than real time<br>
(i.e. the time it takes to play the WAV) and is only restricted by CPU<br>
speed and licenses. You'd need to ask Cepstral the details, but my<br>
simple tests have shown that it only uses one CPU per command though<br>
some of the processing of multiple command is on multiple CPUs. But I<br>
think the licensing mechanism prevents multiple commands running<br>
completely simultaneously on multiple CPUs. I think the "not<br>
licensed" speech is only inserted when you have no license at all -<br>
all that happens if you try to run multiple commands is that they are<br>
just delayed until there is a free license. I don't think quality<br>
will ever be degraded - it's just a question of CPUs and licenses that<br>
will determine your throughput.<br>

</div>Not unless something in Cepstral or FS is going badly wrong!<br>

<br>
</div>Depends on the length of your prompts and number and speed of CPUs and<br>
anticipated simultaneous calls. Try testing the time for a typical<br>
prompt and work it out from there.<br>
