Abstract
Abstract In a system ( 10 ) for adding speech recognition capabilities to Java, there is provided a speech recognition server ( 18 ) coupled to a Java application ( 24 ) through an application program interface ( 20 ). The Java application ( 24 ) dynamically specifies a grammar ( 56 ) to the application program interface ( 20 ), which communicates the grammar ( 56 ) to the speech recognition server ( 18 ). The speech recognition server ( 18 ) receives the grammar ( 56 ) and a speech input ( 66 ). Upon receiving the speech input ( 66 ), the speech recognition server ( 18 ) performs speech recognition and generates a result ( 58 ) based on the grammar ( 56 ). The application program interface ( 20 ) communicates the result ( 58 ) to the Java application ( 24 ), which performs an action based on the result ( 58 ) received.

Claim 1
Independent Claim
116 words
A system for facilitating a speech interface to Java comprising: a speech recognition server operable to receive a grammar and a speech input, the speech recognition server further operable to perform speech recognition in response to the speech input and to generate a result based on the grammar; at least one Java application operable to dynamically specify the grammar, to receive the result and to perform an action based on the result; and an application program interface operable to receive the grammar, to communicate the grammar to the speech recognition server and, in response to the speech recognition, to receive the result from the speech recognition server and to communicate the result to the Java application.
Claim 2
Independent Claim
116 words
A system for facilitating a speech interface to Java comprising: a speech recognition server operable to receive a grammar and a speech input, the speech recognition server further operable to perform speech recognition in response to the speech input and to generate a result based on the grammar; at least one Java application operable to dynamically specify the grammar, to receive the result and to perform an action based on the result; and an application program interface operable to receive the grammar, to communicate the grammar to the speech recognition server and, in response to the speech recognition, to receive the result from the speech recognition server and to communicate the result to the Java application.
Claim 3
Dependent Claim
32 words
The system of claim 1 , wherein the speech recognition server comprises: a speech engine operable to perform speech recognition; and a grammar data structure operable to receive and store the grammar.
Claim 4
Dependent Claim
61 words
The system of claim 1 , wherein the speech recognition server comprises: a speech engine operable to perform speech recognition and generate the result; a grammar data structure operable to receive and store the grammar an application data structure operable to track the status of the Java application, and to track the status of a grammar associated with the Java application.
Claim 5
Dependent Claim
27 words
The system of claim 3 , wherein the application data structure comprises a speech focus, operable to restrict communication of the result to an intended Java application.
Claim 6
Dependent Claim
89 words
The system of claim 1 , wherein the speech recognition server comprises: a speech engine operable to perform speech recognition and generate the result; an application data structure operable to track the status of the Java application, and to track the status of a grammar associated with the Java application; and a set of regular grammars in a directed acyclic graph operable to receive the grammar and to dynamically modify the contents of the set of regular grammars in a directed acyclic graph in response to receiving the grammar.
Claim 7
Dependent Claim
27 words
