'used' in the structure 'used to'
According to dictionaries, the noun 'use' is pronounsed as /ju:s/, the verb 'use' is pronounced as /ju:z/ and I read that 'used' in the structure 'used to' pronounced /ju:st/ but I had learned that 'ed' should be pronouned /d/ after sonants (звонких согласных), so it should sound as 'ju:zd'.
Is the transcription /ju:st/ correct for the structure 'used to'?
Thank you )
