We all do it. We can talk all day to friends, colleagues and family without uttering a singled ‘um’ or ‘erm’. But sit in front of a microphone to record a podcast and they pour out.

So how do professional broadcasters and newsreaders speak without making these unwanted noises? Practice, practice, practice – and a heavy dollop of self discipline.

Sure, we can edit our podcasts to remove these noises; but it can get boring after a while and it is time consuming – so far as I know – there is not an app for that (yet).

The best way to solve this is to train yourself not to make those noises at all.
