"The speech is spoken by Obama" is in the present tense, but it's in the passive voice and a bit cumbersome.
Passive voice is when the subject is placed in the object position (it receives the action of the verb instead of performing it). Passive voice isn't incorrect, but sometimes, active voice is better. "Obama speaks the speech" is active voice but still awkward.
"Obama delivers a speech" is present tense.
"Obama gives a speech" is present tense, as well.
Obama wrote his speech.
Obama's speech for his election.
Be as smart as Obama.

Barack Obama has given many speeches.
One tradition Obama kept was his election day basketball game. Obama prepares both a victory speech and a concession speech for election night. He always has two speeches prepared.
If you are quoting directly from President Obama's speech (from a transcription of it, or from the speech as you saw Mr. Obama himself deliver it on radio or TV), it is a primary source. If you are quoting from other people -- reporters or political scientists or columnists who are talking about the speech or giving their opinions of what Mr. Obama said, those are secondary sources.
