Abstract: A voice conversion apparatus includes: an input unit that inputs designation of a conversion destination voice; an extraction unit that analyzes a voice signal of a conversion source voice and extracts time series data including a phoneme and a pitch; an adjustment unit that matches a height of the pitch to a height of the designated conversion destination voice; and a generation unit that inputs the phoneme and the pitch to a deep learning model that learns voice data of many people and is capable of synthesizing a designated person's voice in time-series order, and generates a voice signal obtained by synthesizing the designated conversion destination voice.
