The invention discloses a multi-device and multi-language synchronous translation device and method based on a block chain and double AIs, and relates to the technical field of intelligent translation and
edge computing, the device comprises a translation
machine terminal, an
edge computing node and a
cloud server which form an end-edge-cloud three-level collaborative architecture, a translator terminal collects voice and lip shape information through a multi-mode sensing module, performs preliminary recognition by means of an edge lightweight AI unit, and realizes safe and rapid networking based on a block chain identity unit and an NFC touch networking unit. The
edge computing node deploys a block chain group management module, a semantic collaborative optimization module and a local cache
retransmission module, and is responsible for multi-
language translation, semantic optimization and reliable distribution. The
cloud server realizes
global model training and term
library management; according to the method, low-
delay and high-accuracy multi-device synchronous interactive translation is realized through device
authentication, voice recognition, edge optimization, multi-language
parallel translation and adaptive transmission, and the translation efficiency and security in a multi-user and multi-language scene are remarkably improved.
