The Application Of Acoustic Features In The Voice Converion System

With the development of information technology and computer science, the application of computer pervads every aspect of our lives. In modem life, computer and human being already gets more and more closed with each other.The research on "Human-Computer Interaction Techniques" became a hot issue. People don' t remain the satisfaction with typical inputting instrument using: such as key board & mouse. People prefer to get a more convinent and effective way to interact with compucter. Now "Voice Conversion" comes.In this paper we focus on the topic of voice conversion which makes the computer-human interaction more individualized and effective. And actually it will bring convenience to our real life. This technology is meaningful in theory and application and will be widely accepted on its own merits.Voice conversion is a technque for modifying a source speaker's speech to sound as if it was spoken by a target speaker. Voice conversion will serve as an invaluable tool for many applications in speech technology,such as instant reversion to the other side in chat,also can be used for dubbing movies for TV broadcast and can provide various distinctive voice to speech synthesis.It also can be used in intelligence department.Voice conversion mainly convert a source speaker's acoustic features to target speaker's.Tthis paper's emphasis on researching acoustic fwatures in voice conversion system.In this paper,we have achieve purpose:Firstly,we carries on the research comparison to each kind of acoustic features. Secondly,after the STRAIGHT analyse speech,we used dynamic features optimizes to improve the quality of converted speech.
