have -- (WT) This helping verb "have" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here.

spoken - The word translated as "spoken " means "to say" and "to speak." It is one of the two most common words translated "speak," "say" and "tell," but it has more a sense of addressing and proclaiming.

to -- This word "to" comes from the dative case of the following word that requires the addition of a preposition in English. The most common is a "to" for the English indirect object.
