You did a great job with changing the pacing, tone, and volume to keep it from being monotonous! There were a few moments where the enunciation wasn’t as strong, so try keeping that in mind when you’re doing long reads. Enunciation allows the audience to hear you clearly. Alos, keep in mind the prompt of speaking in a gymnasium without a microphone. When speaking into a large room you will want to project to your audience. You will want to slow down your pace a bit so your words don’t blend in with each other. Projecting also requires engaging your diaphragm to produce nice and supported breaths to allow your voice to travel. Overall, great job and keep on practicing!
