Abstract
A speech input apparatus having a speech input from a user and the method therefor are provided. The speech input apparatus includes a speech template unit providing a plurality of speech templates, an I/O interface outputting and switching the plurality of speech templates to the user to be selected in response to the speech, a speech recognition unit recognizing the speech to provide a result; a database unit storing data; and a search unit searching the database unit for specific data in response to the result.
Claims12
A speech input apparatus having a speech input from a user, comprising:
- a speech template unit providing a plurality of speech templates;
- an I/O interface communicating the said users for the selection among said plurality of speech templates;
- a speech recognition unit recognizing said speech to provide a result;
- a database unit storing data;
- and
- a search unit searching said database unit for specific data in response to said result.
A speech input method comprising steps of:
- (a) providing a plurality of speech templates;
- (b) switching said plurality of speech templates;
- (c) selecting one of said plurality of speech templates as a selected speech template;
- (d) activating one model corresponding to said selected speech template;
- (e) inputting a speech;
- (f) recognizing said speech according to said model, and generating a result;
- (g) providing said result to a search unit;
- and
- (h) searching for a specific data in a database unit in response to said result.
A method for dynamically updating the constraint-model unit that includes lexicon models and language models for a speech input apparatus, wherein said speech input apparatus comprises a database unit and said constraint-model unit, and said database unit contains some content, comprising steps of:
- (a) converting said content into a lexicon model and a language model for recognition;
- (b) updating the indices to said content for database search;
- (c) storing said lexicon model and said language model to said constraint-model unit;
- and
- (d) storing said indices in said database unit.
