This is a technology based age. We are continuously using technologies in every sphere of our life. So, with that consequence, Google has introduced Voice Assistant with Artificial Intelligence (AI). It won’t speak like robots anymore. Rather it would speak in the way a human being does.
Google is exploiting their Text-To-Speech or Tacotron 2 System for this purpose. Takotron system is a sequence-t-sequence feature prediction network which can map the character embeddings in Mel-scale spectrogram. Besides, using a modified wave net model as decoder time-domain wave firms would be brought under a process from spectrogram. And then, AI will be able to speak up like human beings.
