PAL Script - Hourly Time Signal (The Pips) With Spoken Time

This PAL Script will play the pips at the top of the hour followed by the spoken hour, e.g. "It is precisely 8 o'clock."  You should download the time signal track at the bottom of this document, add it to SAM Broadcaster in its own 'TimeSignal' playlist or category and run the script.  The PAL Script is also available to download from the bottom of this page.

 Note: This script used Google Translate to generate the audio however, Google have changed the way their system works which means there will be no audio.  This script remains available as a guide to implementing this type of feature and in case anyone finds a comparable service to replace Google Translate.
