MULTILINGUAL SPEECH SYNTHESIS AND CROSS-LANGUAGE VOICE CLONING
A method (300) includes receiving an input text sequence (114) to be synthesized into speech (150) in a first language and obtaining a speaker embedding (116a), the speaker embedding specifying specific voice characteristics of a target speaker (10) for synthesizing the input text sequence into speech that clones a voice of the target speaker. The target speaker includes a native speaker of a second language different than the first language. The method also includes generating, using a text-to-speech (TTS) model (100), an output audio feature representation (119) of the input text sequence by processing the input text sequence and the speaker embedding. The output audio feature representation includes the voice characteristics of the target speaker specified by the speaker embedding.
