KR950013195A - TV's Voice Synthesis Recorder - Google Patents

Abstract

The present invention relates to an apparatus for reproducing and synthesizing a voice of a TV, and in the related art, when a voice corresponding to a broadcast signal is output, there is no storage function of voice data, and thus the voice cannot be replayed and replayed. there was.

In view of this point, the present invention synthesizes the voice signal and the output of the external microphone according to the voice synthesis mode setting, and stores the sampled or unsynthesized voice signal synthesized according to the input of the voice reproducing key. It is designed to reproduce the stored voice signal by selection. Accordingly, the present invention not only can perform voice synthesis by mixing the voice of the external microphone input viewer with the broadcast signal according to the selection of the voice synthesis input selection key, but also records the voice and outputs it in time by selecting the voice regeneration key. You can hear the voice of one sentence again and use it for educational purposes.
