Virtual object mouth shape driving method and device, and terminal equipment

The embodiments of the invention disclose a virtual object mouth shape driving method and device, terminal equipment and a computer readable storage medium. The method comprises the following steps that a TTS data stream obtained by converting a target text is acquired; according to a mapping relationship between a preset text and a pinyin and a mapping relationship between a preset pinyin and a phoneme, the target text is converted into a phoneme sequence; according to the phoneme sequence and the TTS data stream, an animation playing sequence of the virtual object is constructed; the TTS data stream is analyzed to obtain the energy value at a single moment; and in the process of playing the virtual object according to the animation playing sequence and playing the speech according to theTTS data stream, the energy value is set to the mouth shape animation of the virtual object in real time to control the opening degree of the mouth shape of the virtual object. According to the embodiments of the invention,
