Hear six early presidents in their own voices, restored (1908-1922)
Taft in 1908, Roosevelt, Wilson and Taft in 1912, Coolidge and FDR in 1920, Harding in 1921: public domain phonograph speeches, each original next to its restoration.
Before radio, the closest most Americans came to hearing a president was a phonograph record. Between 1908 and 1922 candidates and presidents recorded short speeches for Victor and for the Nation's Forum series, made acoustically, by speaking into a horn, with no microphone. Those discs survive, but the voices sit under a century of hiss, crackle and horn resonance.
We restored them with Diffio AI, our speech restoration tool. This page collects six voices from those years, from William Howard Taft in 1908 to Franklin D. Roosevelt in 1920. Each pair below is the same passage from the same disc, original first, matched for loudness, and each restored excerpt was checked word for word against the original. All of the recordings were published before 1923, so they are in the public domain in the United States.
William Howard Taft, 1908: "Functions of the Next Administration"
Taft recorded a set of campaign speeches for Victor at Hot Springs, Virginia, on August 5, 1908, while he was the Republican nominee. In this one he promises to carry on Theodore Roosevelt's fight against lawbreaking corporations:
"The chief function of the next administration, in my judgment, is distinct from, and a progressive development of, that which has been performed by President Roosevelt. The chief function of the next administration is to complete and perfect the machinery by which these standards may be maintained, by which the lawbreakers may be promptly restrained and punished, but which shall operate with sufficient accuracy and dispatch to interfere with legitimate business as little as possible."

Roosevelt, Wilson and Taft, 1912
In the fall of 1912 all three candidates recorded for Victor. Roosevelt, running as a Progressive, answered the trusts and party bosses: "They dread you, the people." Wilson took apart Roosevelt's plan to regulate monopoly, and Taft, now the sitting president, asked "Who are the people?" All three restorations, with the disc labels and a short video, are on our 1912 election page. Here is Roosevelt:

Calvin Coolidge, 1920: "Law and Order"
Coolidge recorded "Law and Order" for the Nation's Forum series in 1920 as governor of Massachusetts, the year he was elected vice president. It is one of the earliest recordings of his voice:
"Government is not, must not be, a cold, impersonal machine, but a human and more human agency, appealing to the reason, satisfying the heart, full of mercy, assisting the good, resisting the wrong, delivering the weak from any impositions of the powerful. This is not paternalism, it is not a servitude imposed from without, but the freedom of a righteous self-direction from within."

Franklin D. Roosevelt, 1920: "Americanism"
Twelve years before he was elected president, Roosevelt was the Democratic candidate for vice president. According to the FDR Library, his Nation's Forum record, "Americanism," gives excerpts from the speech accepting that nomination at Hyde Park on August 9, 1920. It closes on the First World War:
"The other half is not won yet. The cry of the French at Verdun, 'They shall not pass,' and the cheer of our own men in the Argonne, 'We shall go through,' these were essential glory. Yet they are incomplete. To them we must write the binding finish: it shall not occur again. For America demands that the crime of war shall cease."

Warren G. Harding, 1921: opening the Washington Naval Conference
On November 12, 1921, the day after he buried the Unknown Soldier at Arlington, Harding opened the Washington Conference on the Limitation of Armament. He recorded the address for Victor in May 1922, on the other side of the disc that carries his Hoboken address over the war dead, and directed that the royalties go to the American Red Cross:
"Gentlemen of the Conference, the United States welcomes you with unselfish hands. We harbor no fears. We have no sordid ends to serve. We suspect no enemy. We contemplate or apprehend no conquest. Content with what we have, we seek nothing which is another's. We only wish to do with you that finer, nobler thing which no nation can do alone. We wish to sit with you at the table of international understanding and good will."

The other side, Harding's 1921 address at Hoboken over 5,212 American war dead, has its own page with the full restored disc.
