Make the. NET program speak, and the. NET program will speak.
During the development process, it is necessary to enable the program to automatically play the voice. If it is a single recording, it is too troublesome. during the development process, it is found that. NET already comes with this function.Type type = Type. GetTypeFromProgID ("SAPI. SpVoice"); dynam
