  • Patent number: 7299174
    Abstract: To implement scalable coding, a base layer coding section encodes an input signal to obtain base layer coded information, which is decoded by a base layer decoding section to obtain a base layer decoded signal and long term prediction information (pitch lag). An adding section inverts the polarity of the base layer decoded signal to add to the input signal, and obtains a residual signal. An enhancement layer coding section encodes a long term prediction coefficient calculated using the long term prediction information and the residual signal to obtain enhancement layer coded information. Also using the long term prediction information, an enhancement layer decoding section decodes the enhancement layer coded information to obtain an enhancement layer decoded signal. An adding section adds the base layer decoded signal and enhancement layer decoded signal to obtain a speech/sound signal.

  • Patent number: 7266491
    Abstract: A method of, and system for, generating a sentence from a semantic representation maps the semantic representation to an unordered set of syntactic nodes. Simplified generation grammar rules and statistical goodness measure values from a corresponding analysis grammar are then used to create a tree structure to order the syntactic nodes. The sentence is then generated from the tree structure. The generation grammar is a simplified (context free) version of a corresponding full (context sensitive) analysis grammar. In the generation grammar, conditions on each rule are ignored except those directly related to the semantic representation. The statistical goodness measure values, which are calculated through an analysis training phase in which a corpus of example sentences is processed using the full analysis grammar, are used to guide the generation choice to prefer substructures most commonly found in a particular syntactic/semantic context during analysis.

  • Patent number: 7194411
    Abstract: Web pages and other text documents displayed on a computer are reformatted to allow a a user who has difficulty reading to navigate between and among such documents and to have such documents, or portions of them, read aloud by the computer using a text-to-speech engine in their original or translated form while preserving the original layout of the document. A “point-and-read” paradigm allows a user to cause the text to be read solely by moving a pointing device over graphical icons or text without requiring the user to click on anything in the document. Hyperlink navigation and other program functions are accomplished in a similar manner.
