The invention discloses a simultaneous interpretation booth used for translating Sichuan accent and Italian based on a GSP algorithm. The simultaneous interpretation booth comprises 1) a simultaneousinterpretation booth main body portion, 2) a simultaneous interpretation booth cable, an audio input microphone and an audio output earphone, 3) a Sichuan accent audio big data information database stored in cloud, 4) Italian speech big data information database stored in the cloud, 5) a Chinese grammar and pronunciation rule database stored in the cloud, 6) an Italian grammar and pronunciation rule database stored in the cloud, and 7) a GSP algorithm artificial intelligence module carried in a cloud calculation center. The simultaneous interpretation booth is used for providing the artificialintelligent simultaneous translation for large international conferences, the Sichuan accent of a Chinese user and the Italian can be identified and translation accuracy is high. The translation is more stable than human translation, and translation errors generated because translation personnel is fatigue along with the extension of meeting time are avoided.
