Hello James,
We replied to your ticket on this issue, but I'm also posting the response here in case it is helpful to anyone else.
I synthesized "Ich sollte weggehen" in both the Katrin and the Matthias voices on our demo page. The only substantial difference I found was that the final unit in "sollte" //z ao1 l. t ah0// is pronounced in a more elongated manner.
Could you verify that the pronunciation you expect would be as follows?
(q ih1 c)(z ao1 l. t ah0)(v eh1 k. g e1. en0)
Please refer to

If the only problem is the elongation of the /ah0/, thank you for bringing this to our attention, and it will be fixed in a future release.
If there is more to this issue, please let me know.
Thanks,
The Cepstral Support Team
