  • Publication number: 20130030805
    Abstract: According to one embodiment, a transcription support system supports transcription work to convert voice data to text. The system includes a first storage unit configured to store therein the voice data; a playback unit configured to play back the voice data; a second storage unit configured to store therein voice indices, each of which associates a character string obtained from a voice recognition process with voice positional information, for which the voice positional information is indicative of a temporal position in the voice data and corresponds to the character string; a text creating unit that creates the text in response to an operation input of a user; and an estimation unit configured to estimate already-transcribed voice positional information indicative of a position at which the creation of the text is completed in the voice data based on the voice indices.

  • Publication number: 20130030806
    Abstract: In an embodiment, a transcription support system includes: a first storage, a playback unit, a second storage, a text generating unit, an estimating unit, and a setting unit. The first storage stores the voice data therein; a playback unit plays back the voice data; and a second storage stores voice indices, each of which associates a character string obtained from a voice recognition process with voice positional information, for which the voice positional information is indicative of a temporal position in the voice data and corresponds to the character string. The text creating unit creates text; the estimating unit estimates already-transcribed voice positional information based on the voice indices; and the setting unit sets a playback starting position that indicates a position at which playback is started in the voice data based on the already-transcribed voice positional information.

  • Publication number: 20130030794
    Abstract: According to one embodiment, a speaker clustering apparatus includes a clustering unit, an extraction unit, and an error detection unit. The clustering unit is configured to extract acoustic features for speakers from an acoustic signal, and to cluster utterances included in the acoustic signal into the speakers by using the acoustic features. The extraction unit is configured to acquire character strings representing contents of the utterances, and to extract linguistic features of the speakers by using the character strings. The error detection unit is configured to decide that, when one of the character strings does not fit with a linguistic feature of a speaker into which an utterance of the one is clustered, the utterance is erroneously clustered by the clustering unit.

  • Patent number: 8275730
    Abstract: States included in a deterministic finite automaton are classified into states having the same input symbols associated with outgoing transitions and the same finality, and a calculates an intersection set between each of the state sets and a set of transition destination states which is obtained by translating each of states included in the state sets, until the number of states included in the intersection set becomes equal to one, while regarding the set of the transition destination states for each of the input symbol included in the intersection set as new state sets, and plural indistinguishable states are merged into one state by tracing a route in a reverse direction to a transition direction, when the number of states has become equal to one.

  • Publication number: 20120046935
    Abstract: According to one embodiment, a finite state transducer determinizing device includes a symbol determination unit, a state merging unit, and a single-value processing unit. The symbol determination unit generates an identification symbol different from an input symbol assigned to each transition of a finite state transducer. The state merging unit extracts one or more states at a transition destination by the same input symbol from among the states of the finite state transducer and generates states having the extracted states as sub-states. The single-value processing unit applies the input symbol assigned to each transition of the finite state transducer or the identification symbol as an input symbol of a transition between the states generated by the state merging unit to perform determinizing.

  • Patent number: 8078449
    Abstract: In a speech translation apparatus, a correspondence storage unit stores therein identifiers of terminals and usage languages used in the terminals associated with each other. A receiving unit receives a source speech from one of the terminals. A translating unit acquires usage languages from the correspondence storage unit, and generates a translated speech by using each of the acquired usage languages as a target language. When the translated speech is generated in any one of the target languages, a determining unit determines whether it has been generated in all the target languages. If the translated speech has been generated in all the target languages, an output unit outputs the translated speech. A sending unit sends the translated speech to each of the terminals.

  • Publication number: 20050259959
    Abstract: A media data memory stores media data including at least one of speech data and image data both playable in time series. A play control display unit displays a plurality of time figures. Each time figure corresponds to a play time of a part of the media data in time series order. A data selection unit selects at least one time figure from the plurality of time figures through the play control display unit. A play control unit moves a play position to a part of the play time corresponding to the at least one time figure in the media data. A play unit plays the media data from the play position moved by the play control unit.
