12. A spoken word generation method for speech recognition, executed by a computer, comprising: receiving, by at least one input device, a plurality of input signals, and detecting, by a mode detection module, the plurality of input signals, wherein the plurality of input signals at least includes at least one sound signal; when a specific sound event being detected in the plurality of input signals or at least one control signal being included in the plurality of input signals, outputting a speech training mode and performing, by a speech training module, a training process on the at least one sound signal and outputting a training result; and when no specific sound event being detected in the plurality of input signals and no control signal being included in the plurality of input signals, outputting a speech recognition mode and performing, by a speech recognition module, a speech recognition process on the at least one sound signal and outputting a recognition result, training at least one word model synonymous to at least one preset word by marking left and right boundaries of the specific sound event or the at least one control signal as to indicate the at least one preset word and at least one new word to be added synonymous to the at least one preset word inputted by at least one user and establishing a connection between the at least one word model and the at least one preset word.
18. The method as claimed in claim 12 , wherein the method uses a number of triggers or a triggering scheme of a device to detect whether the at least one control signal is included in the plurality of input signals.
