What is the common English name for Hirohito's 1945 radio broadcast announcing Japan's surrender?

Hirohito's 1945 radio broadcast announcing Japan's surrender is commonly called the Jewel Voice Broadcast.

The name translates the Japanese term Gyokuon-hōsō, referring respectfully to the emperor's voice. Hirohito recorded the Imperial Rescript on the Termination of the War on August 14, and the recording was transmitted by NHK at noon on August 15, 1945.

The address was deliberately formal and used Classical Japanese, a style many ordinary listeners found difficult to understand. Hirohito spoke indirectly about accepting the Allied declaration rather than plainly saying, in everyday language, that Japan had surrendered. Radio announcers clarified the meaning after the recording ended.

The broadcast was historically significant because it was the first known occasion on which the Japanese emperor's voice was heard by the general public. An attempted military coup sought to prevent the recording from being transmitted, but the recording was hidden and successfully taken to the broadcasting station.
