20100076768 | SPEECH SYNTHESIZING APPARATUS, METHOD, AND PROGRAM - Disclosed is a speech synthesizing apparatus including a segment selection unit that selects a segment suited to a target segment environment from candidate segments, includes a prosody change amount calculation unit that calculates prosody change amount of each candidate segment based on prosody information of candidate segments and the target segment environment, a selection criterion calculation unit that calculates a selection criterion based on the prosody change amount, a candidate selection unit that narrows down selection candidates based on the prosody change amount and the selection criterion, and an optimum segment search unit than searches for an optimum segment from among the narrowed-down candidate segments. | 03-25-2010 |
20100211393 | SPEECH SYNTHESIS DEVICE, SPEECH SYNTHESIS METHOD, AND SPEECH SYNTHESIS PROGRAM - A speech synthesis device is provided with: a central segment selection unit for selecting a central segment from among a plurality of speech segments; a prosody generation unit for generating prosody information based on the central segment; a non-central segment selection unit for selecting a non-central segment, which is a segment outside of a central segment section, based on the central segment and the prosody information; and a waveform generation unit for generating a synthesized speech waveform based on the prosody information, the central segment, and the non-central segment. The speech synthesis device first selects a central segment that forms a basis for prosody generation and generates prosody information based on the central segment so that it is possible to sufficiently reduce both concatenation distortion and sound quality degradation accompanying prosody control in the section of the central segment. | 08-19-2010 |
20100223058 | SPEECH SYNTHESIS DEVICE, SPEECH SYNTHESIS METHOD, AND SPEECH SYNTHESIS PROGRAM - A speech synthesis device includes a pitch pattern generation unit ( | 09-02-2010 |
20100305949 | SPEECH SYNTHESIS DEVICE, SPEECH SYNTHESIS METHOD, AND SPEECH SYNTHESIS PROGRAM - It is possible to provide a speech synthesis device, speech synthesis method, and speech synthesis program which can improve a speech quality and reduce a calculation amount with a preferable balance between them. The speech synthesis device includes: a sub-score calculation unit ( | 12-02-2010 |
20110106538 | SPEECH SYNTHESIS SYSTEM - This speech synthesis system includes a server device and a client device. The client device accepts text information representing text, and transmits a speech element request to the server device. The server device stores speech element information. The server device receives the speech element request transmitted by the client device and, in response to the received speech element request, transmits speech element information to the client device so that the speech element information is received by the client device in a different order from an order of arrangement of speech elements in speech corresponding to the text. The client device executes a speech synthesis process by rearranging the speech element information so that speech elements represented by the received speech element information are arranged in the same order as the order of arrangement of the speech elements in the speech corresponding to the text. | 05-05-2011 |
20110137655 | SPEECH SYNTHESIS SYSTEM - A speech synthesis system includes a server device and a client device. The server device stores speech element information and speech element identification information in association with each other so that, in a case that speech element information representing respective speech elements included in speech uttered by a speech registering user are arranged in the order of arrangement of the speech elements in the speech, at least one of speech element identification information identifying the respective speech element information has different information from information arranged in accordance with a predetermined rule. The client device transmits speech element identification information to the server device based on accepted text information. The client device executes a speech synthesis process based on the speech element information received from the server device. | 06-09-2011 |
20130024192 | ATMOSPHERE EXPRESSION WORD SELECTION SYSTEM, ATMOSPHERE EXPRESSION WORD SELECTION METHOD, AND PROGRAM - Disclosed is an information display system provided with: a signal analyzing unit which analyzes the audio signals obtained from a predetermined location and which generates ambient sound information regarding the sound generated at the predetermined location; and an ambient expression selection unit which selects an ambient expression which expresses the content of what a person is feeling from the sound generated at the predetermined location on the basis of the ambient sound information. | 01-24-2013 |
20130325477 | SPEECH SYNTHESIS SYSTEM, SPEECH SYNTHESIS METHOD AND SPEECH SYNTHESIS PROGRAM - A speech synthesis system includes: a training database storing training data which is set of features extracted from speech waveform data; a feature space division unit which divides a feature space which is a space concerning to the training data into partial spaces; a sparse or dense state detection unit which detects a sparse or dense state to each partial space which is the divided feature space, generates sparse or dense information which is information indicating the sparse or dense state and outputs the sparse or dense information; and a pronunciation information correcting unit which corrects pronunciation information which is used for speech synthesis based on the outputted sparse or dense information. | 12-05-2013 |
20140012584 | PROSODY GENERATOR, SPEECH SYNTHESIZER, PROSODY GENERATING METHOD AND PROSODY GENERATING PROGRAM - There is provided a prosody generator that generates prosody information for implementing highly natural speech synthesis without unnecessarily collecting large quantities of learning data. A data dividing means | 01-09-2014 |
20140136192 | WAVEFORM PROCESSING DEVICE, WAVEFORM PROCESSING METHOD, AND WAVEFORM PROCESSING PROGRAM - There is provided a waveform processing device for changing power of each pitch waveform of a segment in order to acquire a natural synthesis speech. A power calculation means | 05-15-2014 |
20140149116 | SPEECH SYNTHESIS DEVICE, SPEECH SYNTHESIS METHOD, AND SPEECH SYNTHESIS PROGRAM - There are provided a speech synthesis device, a speech synthesis method and a speech synthesis program which can represent a phoneme as a duration shorter than a duration upon modeling according to a statistical method. A speech synthesis device 80 according to the present invention includes a phoneme boundary updating means 81 which, by using a voiced utterance likelihood index which is an index indicating a degree of voiced utterance likelihood of each state which represents a phoneme modeled by a statistical method, updates a phoneme boundary position which is a boundary with other phonemes neighboring to the phoneme. | 05-29-2014 |
