The acts that limited the freedom for speech during World War 1 was the Sedition Act of 1798 and the Federal Espionage Act of 1917.

Explanation:

Soon after the United States participated in World War 1 in 1917, many leaders emerged with a message for the public that asked them not to participate in the war. They also criticized the decision of the government to participate in the war on the side of allies.

To prevent people from criticizing the government, the government passed a law called the Federal Espionage Act and arrested the criticizers of the government under the Espionage Act of 1917 and the Sedition Act of 1798.
