This BBC Four documentary, titled 'How The Edwardians Spoke' and presented by voice coach Joan Washington (accompanied throughout by a British Sign Language interpreter in the lower right frame), explores a fascinating historical discovery: hundreds of original shellac gramophone recordings of British WWI prisoners of war, recorded between 1915 and 1918 in German prison camps by researchers Alois Brandl and Wilhelm Doegen. Joan travels to the Lautarchiv at Humboldt University in Berlin, where sound expert Jürgen Mahrenholz demonstrates how they preserve these fragile discs. Around 11:24, Mahrenholz uses a tuning fork sounding an 'A' to manually adjust the pitch and turntable playback speed of a 1916 shellac record before playing folk songs and spoken passages. The documentary follows Joan as she visits the descendants of these POWs across Britain—in Cheshire, Wiltshire, and Aberdeen—playing the century-old recordings to family members who are hearing their ancestors' voices for the very first time. Along the way, the program also showcases rare archival audio of notable figures, including suffragette Christabel Pankhurst giving a 1908 speech on women's suffrage at 52:09 and Antarctic explorer Ernest Shackleton recounting his expedition at 53:35. It is extraordinary to hear working-class Edwardian voices captured with such clarity, particularly when contrasted against the silent black-and-white film footage we typically associate with the Great War. The emotional reactions of the living relatives as they listen to their grandfathers and uncles reading the parable of the Prodigal Son or singing traditional songs like 'Loch Lomond' give the historical research a deeply personal heart. It serves as an eye-opening look at how dramatically regional accents, vowel sounds, and local dialects across the British Isles have shifted and softened over the past century.
