Method and apparatus for speed kon version of speech

摘要

The speed of an input speech is changed without changing the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data.;A speech speed conversion apparatus includes a unit (321, 10, 7, 5) for inputting speech, a speech speed conversion unit (11) for changing the speed of the input speech, and a unit (6, 8, 9, 325) for supplying the output of the speech speed conversion unit as output speech to listener's ears. The apparatus further includes a speech speed conversion switch (3, 4) so that speech with changed speed of the input speech is delivered in a period in which the conversion switch is turned on, whereas speech without change of the input speech is delivered when the conversion switch is turned off.
