Voice Emulation or Voice Reproduction is a technique with which individual voices can be reproduced. The reproduction technology for speech or voices is extremely complex and is based on Deep Learning, artificial neural networks and speech synthesis
. Voice reproduction is so advanced that one can mimic voices of different people. Technically, voice rendering involves analyzing a short sample of a subject's speech in many small sets of programs. The programs can replicate and change the speaker's tone of voice and emotions to express different feelings during voice reproduction. The technology for voice reproduction still needs to be improved in terms of development.
