According to an embodiment, a text-to-speech device includes a receiver to receive an input text containing a peculiar expression; a normalizer to normalize the input text based on a normalization rule in which the peculiar expression, a normal expression of the peculiar expression, and an expression style of the peculiar expression are associated, to generate normalized texts; a selector to perform language processing of each normalized text, and select a normalized text based on result of the language processing; a generator generate a series of phonetic parameters representing phonetic expression of the selected normalized text; a modifier modifies a phonetic parameter in the normalized text corresponding to the peculiar expression in the input text based on a phonetic parameter modification method according to the normalization rule of the peculiar expression; and a output unit to output a phonetic sound synthesized using the series of phonetic parameters including the modified phonetic parameter.

Text-to-speech system, text-to-speech method, and computer program product for synthesis modification based upon peculiar expressions

An information display apparatus includes a display device configured to display a video, a speech detection unit configured to detect a playback state of a playback speech, a closed caption display unit configured to generate character information associated with the playback speech and display it on the display device together with the video, and a closed caption display unit configured to carry out a changing control for changing according to the detected playback state a display state of the character information that is displayed on the display device by the closed caption display unit.

Information display apparatus, information display method and program therefor

A word dictionary including sets of a character string which constitutes a word, a phoneme sequence which constitutes pronunciation of the word and a part of speech of the word is referenced, an entered text is analyzed, the entered text is divided into one or more subtexts, a phoneme sequence and a part of speech sequence are generated for each subtext, the part of speech sequence of the subtext and a list of part of speech sequence are collated to determine whether the phonetic sound of the subtext is to be converted or not, and the phonetic sounds of the phoneme sequence in the subtext whose phonetic sounds are determined to be converted are converted.

Speech processing apparatus and program

A closed caption display controller to control a display mode of a closed caption corresponding to a speech of an audio signal, the controller comprises an analysis unit to analyze the speech on a speech quality, an examination unit configured to examine a speech listening level according to a given rule based on an analysis result of the analysis unit, and a determination unit to determine a display mode according to an examination result of the examination unit.

Closed caption control apparatus and method therefor

A closed caption signal processing apparatus comprises a speech recognition unit to recognize speech contents from the speech signal, a speech timing detecting unit to detect a speech timing of the speech contents, a closed caption contents acquisition unit to acquire closed caption contents from the closed caption signal associated with the speech signal, a presentation timing detecting unit to detect a presentation timing of the closed caption contents, an agreement detecting unit to detect an agreement between the speech contents and the closed caption contents, and a time difference calculating unit to calculate a time difference between the speech timing and the presentation timing that are detected on the speech contents and the closed caption contents that agree with each other, respectively.

Closed caption signal processing apparatus and method

A method of generating a free-form surface model includes the steps of applying linear transformation to a lattice polygon model to generate vertices of a free-form surface model corresponding to respective vertices of the lattice polygon model, and generating control points of cubic Bezier curves that connect the vertices of the free-form surface model, and that correspond to respective edges of the lattice polygon model.
