Abstract
A speech signal modification and concatenation method is provided, in which spoken messages having different voice characteristics can be concatenated without causing a sense of incompatibility, and it is possible to efficiently perform addition or modification of spoken messages. In the speech signal modification and concatenation method, when two speech signals having different voice characteristics are concatenated, the speech signals are concatenated by modifying a parameter indicating a character of speech signals in a manner such that the parameter is gradually changed from a value indicating a feature of one of the speech signals to a value indicating a feature of the other speech signal over a predetermined period. Accordingly, a time-scaled change of a feature amount of spoken sounds can be performed; thus, even if two speech signals of different speakers are concatenated, it is possible to avoid an abrupt change of voice characteristics in the concatenation section, and thus possible to concatenate speech signals without causing a sense of incompatibility to listeners.
