Description

Technical Field

[0001] The present application relates to the technical field of interpretation equipment, and in particular to a digital infrared simultaneous interpretation transmitter host and a simultaneous interpretation system. Background Art

[0002] Simultaneous interpretation is a form of language translation primarily used at international conferences, multilingual meetings, and large-scale events. In this mode of interpretation, an interpreter translates the speaker's speech simultaneously, and the translated content is transmitted to the audience, enabling communication among participants speaking different languages.
