SPEECH PROCESSING METHOD AND DEVICE, STORAGE MEDIUM, AND SPEECH SYSTEM |
摘要 |
<p>A speech processing device comprises a spectrum envelope extracting section (14) for extracting the spectrum envelope of an input speech signal, a spectrum envelope transforming section (15) for transforming the spectrum envelope to generate a transformed spectrum envelope, a spectrum fine structure extracting section (16) for extracting the spectrum fine structure of the input speech signal, a transformed spectrum generating section (17) for generating a transformed spectrum by combining the transformed spectrum envelope and the spectrum fine structure, and a speech generating section (18) for generating an output speech signal by using the transformed spectrum. An interfering sound to prevent the content of a conversation speech from being heard through the output speech signal by a third party is emitted.</p> |
