Speech Writing and AI Voice Generation for Wedding Rehearsal

I need assistance in crafting a 2-minute speech from the mother of the groom to the groom, which will be included in a slideshow at the wedding rehearsal. I have a rough draft with disjointed points that need to be transformed into a cohesive speech that tells a story. The speech should include humor specific to the personalities of both the mother of the groom and the groom. Once finalized, I would like to provide a sample of my voice via a recording, and if possible, use AI to match my voice to read the speech. This is an urgent task that needs to be completed within 5 hours.
