Abstract:
1. A voice signal encoding/decoding method for synchronizing a voice signal to a voice signal processor, comprising following steps: encoding the voice signal; and decoding the voice signal; wherein said step of encoding further comprises following steps: (A1). setting at least one of a plurality of synchronous time parameters P (A2). judging whether a time-point at which said voice signal is about to be encoded is one of said synchronous time parameters P (A3). outputting an output port code if the time-point in step A2 is one of said synchronous time parameters, said output port code being for activation of a task; and outputting a voice signal coded value corresponding to said voice signal processed by a voice signal encoding means at said time-point if said time-point is not one of said synchronous time parameters, storing said output port code and said voice signal coded value as a voice signal data in a memory, wherein said output port code is different from said voice signal coded value; and (A4). repeating steps A2 and A3 until an end time of said voice signal being reached; said step of decoding further comprising following steps: (B1). fetching said voice signal data from said memory; (B2). judging whether the time-point at which the voice signal data corresponds to one of said synchronous time parameters P (B3). outputting said voice signal data as said output port code to an output port to activate a task, if said time-point is one of said synchronous time parameters; and outputting said voice signal data as said voice signal coded value to a voice signal decoding means to provide a voice subsignal corresponding to said time-point if said time-point is not one of said synchronous time parameters; and (B4). repeating steps of B 1, B2 and B3 until step B3 has been completed for a last voice signal data in said memory; wherein said voice subsignal is asynchronous to said synchronous time parameters.
