Videos of my Final Research Presentation

While looking through some old USBs I’ve discovered a recording of the final presentation of my Honours Research in late 2014. I had believed this was completely lost, like the video of my BSDCan presentation which was not successfully recorded due to technical issues.

Listening to yourself through a vocal monitor gives a better indication of the pitch and timbre of your voice than just listening to yourself, as the sound reaching your ears from your mouth is affected by resonating through your head, like listening to someone talk through a bone wall covered by a wet blanket. A monitor will therefore be a more accurate reproduction of what you sound like to everyone else than “directly” listening to your own voice.
