What was the 15 August 1945 Japanese radio broadcast announcing surrender called in English?

The 15 August 1945 Japanese radio broadcast announcing surrender was called the Jewel Voice Broadcast in English.

Its Japanese name, Gyokuon-hōsō, literally refers to a broadcast of the emperor’s voice. It was Emperor Hirohito’s recorded reading of the Imperial Rescript on the Termination of the War. The recording was broadcast at noon Japan Standard Time on 15 August 1945.

The address told Japan’s population that the government had accepted the terms of the Potsdam Declaration. Hirohito used formal, classical Japanese, so many listeners found the recording difficult to understand immediately. It was the first time most Japanese civilians had heard the emperor’s voice.

The broadcast announced Japan’s decision, but it did not itself complete the formal legal surrender. That occurred on 2 September, when Japanese representatives signed the Japanese Instrument of Surrender aboard USS Missouri in Tokyo Bay.
