Abstract: The present disclosure discloses a speech processing method and apparatus, a device and a computer storage medium, and relates to speech and deep learning technologies in the field of artificial intelligence technologies. A specific implementation solution involves: acquiring a vocoder feature obtained for text; correcting a value of an unvoiced and voiced (UV) feature in the vocoder feature according to an energy feature and/or a speech spectrum feature in the vocoder feature; and providing the corrected vocoder feature for a vocoder, so as to obtain synthesized speech.
