Abstract: A system and method for improving speech conversion efficiency of Articulatory disorder, The method comprises the following steps: First generate a set of text to be recording (not considered in user difference and model difference). It will cover specific phonemes of language and tone distribution relationship. Then the user can train the voice conversion model (or other voice processing model) based on the voice recorded by the user. At the same time, the generated text will also be changed by the characteristics of the currently adopted model (For example: by changing the time-frequency resolution relationship of sentences in the text). Then generate more representative texts so that users can read more helpful training corpus to improve the processing efficiency of the system.

Abstract: A fixing bracket for holding an expansion card in a computer without screws includes first and second fixing frames and an elastic member connected to the first and second fixing frames. The two fixing frames define a receiving space for the expansion card. The first fixing frame can be moved relative to the second fixing frame, or the second fixing frame can be moved relative to the first fixing frame, by applying an external force to deform the elastic member. When the external force is released, the elastic member restores and clamps the expansion card in place until disassembly by the same process.
