VOICE CUSTOMIZATION FOR SYNTHETIC SPEECH GENERATION
This abstract first appeared for US patent application 20250014567 titled 'VOICE CUSTOMIZATION FOR SYNTHETIC SPEECH GENERATION
Original Abstract Submitted
voice customization is an application of voice synthesis that involves synthesizing speech having certain voice characteristics, and/or modifying the voice characteristics of human speech. certain techniques for voice customization may be used in conjunction with compressing speech for storage and/or transmission. for example, speech may be received at a first device and transformed into a latent representation and/or compressed for storage and/or transmission to a second device. the system may use normalizing flows to transform the source audio to a latent representation having a desired variable distribution, and to transform the latent representation back into audio data. a flow model may be conditioned using first speech attributes when transforming the source audio, and an inverse flow model may use second speech attributes when transforming the latent representation back into audio data. the first and/or second speech attributes may be modified to alter voice characteristics of the transmitted speech.
