You did a great job with your enunciation! Everything sounded clear and easily understandable. I did hear a few plosives in there when you said your “p”s, so to avoid that you should make sure you have a pop filter on your microphone. If you already have one and it is still sounding strong, try moving just a few inches back from your microphone to allow the air to slow down before it gets to the microphone. Keep in mind the prompt of being in a gymnasium without a microphone. You will want to project your voice as if you are speaking into a large room. Engage your diaphragm to get strong supported breaths behind your voice. Also, try slowing down a bit to allow your audience to process the information you are giving them, as well as avoid your words blending together too much. Keep up the good work!
