The invention discloses an intelligent voice linkage speaking implementation method and system. The system mainly comprises an audio device, a video device, a storage server, a media server, a management server and client-side main hardware equipment. A C/S structure is adopted in software. The method mainly comprises the steps that according to intelligent voice linkage speaking, condition voices are triggered through the video device for automatic speaking; the speaking function can be started through client-side software to carry out site voice speaking with the front-end video device and a voice device. Theoretically, the access of infinite user sides can be supported by a server, and is mainly decided by the bandwidth and computer performance. According to the method and system, the speaking warning and real-time speaking communication between objects (equipment) and people in the unattended operation environment and the real-time work environment can be achieved, efficiency is improved, and safety is guaranteed.
