Forum:Pre-recorded Dalek voices for Mission to the Unknown

I have heard that the Dalek voices by Peter Hawkins and David Graham were pre-recorded prior to the studio recording session for Mission to the Unknown on Friday 6 August 1965.

Why was this, and is this the first and only time in the series' history that the Dalek voice artistes were not present in the studio for the actual recording?
