The research inrepparttar field of Natural Language Processing usually assumesrepparttar 150537 existence of a syntactic "Generative Engine" that combines words and word-like elements into syntactic structures, and then sometimes displaces them by "syntactic movement". A Linguistic Parser must "undo" allrepparttar 150538 effects of syntactic movement, which results in a structure whererepparttar 150539 relations betweenrepparttar 150540 words are represented more directly.

In recent years, a new theoretical framework was introduced, in whichrepparttar 150541 syntactic combinatorial system does not stop atrepparttar 150542 level ofrepparttar 150543 words. Instead,repparttar 150544 same "Generative Engine" continues all-the-way-down into morphology. The various parts ofrepparttar 150545 same word correspond torepparttar 150546 different areas ofrepparttar 150547 syntactic tree, and then are brought together by multiple applications of movement.

Within this Constructionalist Framework,repparttar 150548 syntactic is not a tree of words - it is a tree made of sub-lexical elements like roots, prefixes, suffixes, etc. The components of a single verb are spread all overrepparttar 150549 parse tree.

Correspondingly,repparttar 150550 function of a Linguistic Parser is different. The goal ofrepparttar 150551 parsing is to "reconstruct" every such sub-lexical element into its original place inrepparttar 150552 syntactic tree.

By undoingrepparttar 150553 effects of syntactic movement, "Constructionalist Parsing" producesrepparttar 150554 syntactic trees where atomic constituents of every word are distributed through such a "reconstructed" syntactic tree. Every constituent is restored into its appropriate location inrepparttar 150555 tree, whererepparttar 150556 context for its semantic contribution is found in immediately adjacent locations.

Text To Speech - It's Simple

Looking for a natural voice speech engine? Curious about what software can read your e-mails. Here isrepparttar latest TTS (text-to-speach) news.

AT&T Natural Voices

AT&T Natural Voices are available in 16khz or 8khz Versions. The 16khz versions have a richer, fuller sound and are more natural sounding. The 8khz version is slightly less expensive and takes up less disk space, but generally doesn't sound quite as good. A good analogy might be that 16khz voices sound like voices over FM Radio, while 8khz voices sound much more like voices overrepparttar 150171 telephone.


Kate and Paul are US English voices, available in 16khz or 8khz versions, supporting SAPI5 Speech applications including all Products, most newer TTS programs from other companies, as well as TTS functions built into Windows XP. Each voice requires slightly under 300mb of disk space, and is available on CD or via download. They support speed and pitch adjustments, and require a minimum of Pentium II, 400mhz with 128mb RAM.
