JFK's lost speech recreated
The company said it took them eight weeks to put the speech together, during which JFK discusses America's standing in the world and the cost of maintaining its security.
The project to create the recording was commissioned by Irish company Rothco and completed in partnership with The Times newspaper.CereProc said that they analysed recordings of hundreds of JFK's speeches and split them into smaller "phonetic units" to reproduce the 55-year-old speech.

Lead voice engineer Chris Pidcock told Radio Scotland's John Beattie programme: "We use machine learning and artificial intelligence techniques just to try and figure out how he moves his pitch and the duration of his sounds through his sentences."That was a big part of the project because we didn't want his intonation to be a boring and standard intonation."We took his existing speeches and material and we cut it up into tiny pieces and stitched it back together into a new speech."JFK had a really unique speaking style and getting his intonation correct was something that we had to spend some time on."The company said the technology would be used in future to help those losing their voices through illness or accident so that they could retain their own individual sound and avoid the robotic tones associated with the late Stephen Hawking.
