I would like to ask the native speakers how to say a sentence like this : " The performance of this method is considered to be optimal" .   Since the word 'considered' is the past participle, it is necessary to pronunciate an extra sound 'd' at the end of the word 'consider'.  But it is difficult to pronunciate 'tu' after the 'd' sound.  how do you say this sentence?  Does the sound 'd' need to be pronunciated ?   Another question is that : a sentence like this " I try to find out today's newspaper". How do you say the phrase 'find out' ?  Is this phrase(find out) pronunciated as like ' fain - dout '  or 'fain-out' ?  Does the sound 'd' need to be pronunciated ?   The last question: a sentence like this : I like dogs and cats.  Here the sound 'd' at the end of the word 'and' need to pronunciated ?  I find that many people seem to pronunciate 'and' as like 'an'.  The sound 'd' is  skipped.
