The invention discloses a voice transmission method based on channel associated signaling. The method comprises the following steps that: 1) a voice transmitting end transmits a voice start signaling to a voice receiving end when initiating voice call, and then, takes the voice superframe as the basic unit to execute voice transmission, wherein the voice superframe is composed of multiple voice burst frames; 2) a voice frame synchronization word FS1 and a channel associated signaling field (CCF) are inserted into an effective load region of each voice burst frame, wherein the CCF comprises a channel associated signaling unit; and 3) multiple channel associated signaling units form one voice channel associated signaling, one voice channel associated signaling is transmitted when each voice superframe is transmitted, so as to realize a special function needed for the voice transmission process, and after the voice is transmitted overall, the voice transmitting end transmits one voice ending signaling to the voice receiving end so as to end the voice transmission. According to the method provided by the invention, multiple channel associated signaling units form one voice channel associated signaling, and the functions, such as access delaying and forced releasing, can be finished.
