Language-oriented user interfaces for voice activated services
First Claim
1. A method for defining a temporal prompting syntax for a voice actuated user interface, the method comprising:
- identifying an initial value for each of one or more syntax parameters from samples of dialogue in a conversational language of a target community; and
specifying an initial temporal syntax for the user interface based on the one or more identified initial values.

Abstract
A comprehensive system is provided for designing a voice activated user interface (VA UI) having a semantic and syntactic structure adapted to the culture and conventions of spoken language for the intended users. The system decouples the content dimension of speech (semantics) and the manner-of-speaking dimension (syntax) in a systematic way. By decoupling these dimensions, the VA UI can be optimized with respect to each dimension independently and jointly. The approach is general across languages and encompasses universal variables of language and culture. Also provided are voice activated user interfaces with semantic and syntactic structures so adapted, as well as a prompting grammar and error handling methods adapted to such user interfaces.

5. A method for optimizing a prompting syntax of a voice actuated user interface, the method comprising:
-
testing performance of tasks by subjects from a target community using the interface implemented with a command vocabulary and a temporal syntax each selected for the target community; and
modifying the temporal syntax based on results of the testing. - View Dependent Claims (6, 7, 8, 9, 10)

11. A method for defining a prompting syntax for a voice activated user interface, the method comprising:
-
specifying an initial temporal syntax for the user interface based on initial syntax parameter values identified through dialogue analysis; and
modifying the initial temporal syntax based on results of testing user performance with the user interface using a selected command vocabulary with the initial temporal syntax. - View Dependent Claims (12, 13, 14)
