<p><P>PROBLEM TO BE SOLVED: To provide a speech input mode conversion system which makes it possible to operate an interface of a computer only in voice without operating a mechanical input means such as a keyboard. <P>SOLUTION: The system is equipped with a speech input means 1 for inputting a speech, an arithmetic means 3, and an interface managing means 4. The arithmetic means 3 is equipped with a speaking section detection part 11 continuing a speech recognition part 14, a voicing pause detection part 12, and a basic frequency estimation part 13. A speech shift identification part 15 is connected to those voicing pause detection part 12, basic frequency estimation part 13, and speech recognition part 14. The speaking section detection part 11 detects a speaking section from an inputted speech, the voicing pause detection part 12 detects a voicing pause section from the speaking section detected by the speaking section detection part 11, and the basic frequency estimation part 13 calculates respective basic frequencies of speaking sections. <P>COPYRIGHT: (C)2004,JPO</p> |
