  • Publication number: 20090271193
    Abstract: A support device, program and support method for supporting generation of text from speech data. The support device includes a confirmed rate calculator, a candidate obtaining unit and a selector. The confirmed rate calculator calculates a confirmed utterance rate which is an utterance rate of a confirmed part having already-confirmed text in the speech data. The candidate obtaining unit obtains multiple candidate character strings resulting from a speech recognition of an unconfirmed part having unconfirmed text in the speech data. The selector preferentially selects, from among the plurality of candidate character strings, a candidate character string whose utterance time consumed in uttering the candidate character string at the confirmed utterance rate is closest to an utterance time of the unconfirmed part of the speech data.

  • Patent number: 7580159
    Abstract: An image processing apparatus includes a first pattern detecting mechanism, a memory, and a pattern identity determining mechanism. The first pattern detecting mechanism detects a background dot pattern embedded in a background image included in image data of an original image from the image data. The memory stores an anti-copy background dot pattern. The pattern identity determining mechanism compares the detected background dot pattern with the anti-copy background dot pattern stored in the memory and determines that the detected background dot pattern is substantially identical to the anti-copy background dot pattern stored in the memory.
