Abstract: The present invention is provided with: a voice input section that receives a remark (a question) via a voice signal; a reply creation section that creates a voice sequence of a reply (response) to the remark; a pitch analysis section that analyzes the pitch of a first segment (e.g., word ending) of the remark; and a voice generation section (a voice synthesis section, etc.) that generates a reply, in the form of voice, represented by the voice sequence. The voice generation section controls the pitch of the entire reply in such a manner that the pitch of a second segment (e.g., word ending) of the reply assumes a predetermined pitch (e.g., five degrees down) with respect to the pitch of the first segment of the remark. Such arrangements can realize synthesis of replying voice capable of giving a natural feel to the user.

Abstract: In a harmonic adding device, an input/output function part converts a digital sound signal having an input signal level into a digital sound signal having an output signal level determined according to a input/output function and the input signal level. A parameter storage unit stores at least one inflection point. A controller sets the inflection point to the input/output function to enable the input/output function part to add harmonics to the digital sound signal. The input/output function is defined between a positive maximum point and a negative maximum point. The inflection point is set between the positive maximum point and the negative maximum point. The positive maximum point, the inflection point and the negative maximum point are sequentially connected by linear interpolation to formulate the input/output function.
