The schwa sound - individual task

I decided to record the same recording we recorded with Dr. Černá in the beginning of the winter semester. I found interesting to compare the difference between the recording which was recorded 4 months ago and the recording I uploaded today. The main aim was to find all schwas in the text and pronounce every word and sentence correctly. I think there is a big difference between these two recordings. This time, I reduced most of the schwas which really made the pronunciation better. To be honest, 4 months ago I did not really know how to pronounce the schwa sound and that was the problem. Now, I did not say /kapbo:d/ but I said /kʌbəd/ in the word cupboard. I did not say /wud/ but I said /wəd/ as for the weak form of would. The same with could. I did not say /laibrery/ but /ˈlaɪbrəri/ in the word library. The thing is that I really tried to connect all the sentences and avoid saying for example /ænd/ instead of /ənd/, /tu:/ instead of /tə/ etc. concerning the weak forms of these words. As I listened to my recording again, maybe I was too interested in the schwa sound and I forgot to say th sound properly, but it was just in two words I think. I must learn how to concentrate on all the aspects of reading some text like this.
