Excellent read! It felt very genuine and authentic overall. And, good for you on noting that there were a couple of words that were slightly slurred and not clearly spoken. Being able to hear and identify them is a huge thing that will make it easier to catch and correct. It will also save you time if you identify and correct it before submitting files because that way the client won’t have to come back to you for a pick-up later for that.

Now, the only thing missing is the answer to Burger’s question: Who is your audience you were speaking to?

Keep up the great work!

This is solid. Great interpretation. You would be a good fit for an anguished character. Someone who wants to prove something to someone and is frustrated about it. That's what I hear in your voice.
