004 (wilson c) has already pointed out that the original sentence "I am tried to listen" has a grammatical mistake. It should be "I tried to listern", or "I am trying to listen".
In the corrected sentence, "tried " or "am trying" is the "verb", but "listen" is not a verb because it is part of "to listen", which is an infinitive.
We can use more than one verb in a sentence. In any case, the above sentence is wrong. Perhaps you wanted to say "I HAVE tried to listen + to something/someone ..."
In this sentence, 'have', 'tried' and 'listen' are all verbs. 'have tried' is the past perfect tense of 'try'. The word 'have' in this case is an auxiliary verb, 'tried' is a verb. Most of the time we cannot use 2 verbs together. In many cases we must put 'to' beween 2 verbs to separate the two actions. Reading a lot of correct English will be of help for sure!
