Very  -- (WW) The word translated as "very" is the Hebrew word that means "truly" or "certainly," but it sounds like the Greek word with the same meaning. In Greek, the word also means "to reap." This is not the word meaning "very."

truly , --  The word translated as "truly" is the Hebrew word that means "truly" or "certainly," but it sounds like the Greek word with the same meaning. In Greek, the word also means "to reap."

I -- This is from the first-person, singular form of the verb.

tell -- The word translated as "I tell" is the most common word that means "to say," and "to speak,"  but when used with an objective noun or pronoun, the sense is "say of" or "speak of."  When two accusative objects are used, the sense is  "say of him this," or "call him this." The form Jesus uses to describe his own speaking can be either indicative, "I say/tell" or subjunctive, "I should/could say/tell."  It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself." Christ usually uses this word to refer to his own speaking or teaching.

you, -- The "you" here is the second-person, plural pronoun in the form of an object.

missing "that"  -- (MW) The untranslated word "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore."

a -- There is no indefinite article in Greek, but when a word doesn't have a definite article, the indefinite article can be added in English translation.

time   - The word translated as "hour" means a period of time equal to the one-twelfth part of the daylight, like an "hour."

is -- This helping verb indicates the present tense of the verb.

coming, -- The word translated as "come" primarily means "to start out" but Christ usually uses it to mean "come" but not always. It indicates movement, especially its beginning, without indicating a direction toward or away from anything, so it works either as "start," "come," or "go," but it is more like our phrase "being underway." Our English word "show up" captures both the "start" and "come" ideas. See this article for more.

and -- The Greek word translated as "and" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it is can be translated as "not only...but also." After words implying sameness "as."

now -- The Greek word translated as "now" means "now," "at the present moment,""presently," and "as it is."

come , -- (WW) The verb "come" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics. With the genitive object, the sense is "belongs to." It can also be translated as "exists," which works better here.

when - "When" is from an adverb/conjunction that means "when," "as when," "at the time when," and "sometimes."

the -- The word translated as "the" is the Greek definite article, without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more.

It has the same sense as the English not only of listening but of understanding.  It is the most common verb that Christ uses meaning "to hear." It also means "to listen" and "to understand," but amusingly, it also means "to be silent."

the -- The word translated as "the" is the Greek definite article, without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

voice -- (WF) The noun translated as "voice"  means "sound", "speech", "voice",  "cry" [of animals], "sounds" [of inanimate objects], and "report."

Its sense may be "the child of the man." This form is genitive, that is, possessive as well. It could apply to the "voice" or "speech"  but when the verb "hear" has two genitives, the sense is "hear of the speech from the Son."

of -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession.

It has the same sense as the English not only of listening but of understanding.  It is the most common verb that Christ uses meaning "to hear."

live. -- The verb means "live," "to be alive,” “to be full of life," "to be strong," and "to be fresh." So it is life in the sense of having a vital life, strong and growing. Perhaps in English, “thrive” would be more precise.
