The Speech Interactive has been optimized for use over a broadband connection of 256 kbps or greater - we recommend that you use the most up to date browser available.

The Speech Interactive is designed to provide you with a number of different access points to the speech - and to introduce a wealth of 'digital archive' source material to help place the speech in context.

The best way to explore the Speech interactive is to start the player and see what happens! We have provided a few pointers below to get you started.

Start the "player" by clicking on the Play button - you can pause or stop the speech at any point. You can access the source material as the speech is playing in the main viewing area which will scroll from right to left, in synch with the audio.

The speech is organized according to a number of 'themes' each of which is colour-coded and represented visually by the horizontal bars in the viewing area.

All of the source material is classified according to these themes and its appearance reflects how that theme is being developed by Churchill at that particular point in the speech.

The source material is represented through the use of 'Documentary Featurettes' (indicated with a 'D') and 'Information Supplements'. The documentary featurettes provide an in-depth analysis of a particular theme, whereas the information supplements provide supporting contextual snapshots.

So, for example, approximately 12 minutes into the speech Churchill turns his attention to the 'Atomic Bomb', at which point you can read a contextual snapshot about Dr. Oppenheimer, the leader of the team that created the bomb.

A number of other features are designed to help with exploring the speech:

The 'autocue' synchronises the speech transcript with the audio version.

The 'timeline' provides a visual representation of the colour-coded themes as they appear. You can drag the 'puck' along the speech 'timeline' - for example, to get to a part where a specific theme is being elaborated.

The 'Highlights' navigation provides a shortcut to key sections of the speech - the puck will move to that section which will then play automatically. The puck and autocue will return to the beginning of the speech when the highlighted section has finished playing.

The speech audio is approximately 45 minutes long and there are approximately 300 additional sources - or one for every 10 seconds of the speech. Some of these will be added over the next few weeks.
