Have you ever recorded your part on a mobile phone and delivered a presentation?

Have you ever recorded your part on a mobile phone and delivered a presentation? So, this time I had to present to 100 people virtually and due to stuttering issues. I recorded the whole presentation on my phone and when my turn came, I played the video on full volume making sure the sound is delivered crisp and clear. I always try to deliver presentations virtually and not in person. Have you guys ever tried this before? In my case, I don't stutter that much. There are phases when I stutter only during presentations, nowhere other in life.
