Abstract: This invention is an improvement of technology for automatically generating response voice to voice uttered by a speaker (user), and is characterized by controlling a pitch of the response voice in accordance with a pitch of the speaker's utterance. A voice signal of the speaker's utterance (e.g., question) is received, and a pitch (e.g., highest pitch) of a representative portion of the utterance is detected. Voice data of a responsive to the utterance is acquired, and a pitch (e.g., average pitch) based on the acquired response voice data is acquired. A pitch shift amount for shifting the acquired pitch to a target pitch having a particular relationship to the pitch of the representative portion is determined. When response voice is to be synthesized on the basis of the response voice data, the pitch of the response voice to be synthesized is shifted in accordance with the pitch shift amount.

Abstract: A voice synthesizing apparatus includes: a voice inputter (102) configured to input a voice; an obtainer (22) configured to obtain a primary response to the voice inputted by the voice inputter (102); an analyzer (112) configured to analyze whether the primary response includes a repetition target; and a voice synthesizer (24) configured to, in a case where the analyzed primary response is determined to include the repetition target, synthesize a voice from a secondary response that includes the repetition target repeated at least twice to output the voice.

Abstract: A voice interaction method includes acquiring a voice utterance signal representative of an uttered voice, and acquiring a response signal representative of a response voice responsive to a content of the uttered voice identified by voice recognition of the voice utterance signal. The voice interaction method also includes supplying the response signal to a voice player, to have the response voice played by the voice player, and supplying an interjection signal representative of interjection voice to the voice player, to have the interjection voice played by the voice player during a wait period that starts from an end point of the uttered voice and ends at a start of playback of the response voice.

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.
