SALT is an industrial standard that enables speech input/

output for Web applications. Although the core design is

to make simple tasks easy, SALT gives the designers ample

fine-grained controls to create advanced user interface. The

paper exploits a speech input mode in which SALT would

dynamically report partial semantic parses while audio capturing

is still ongoing. The semantic parses can be evaluated

and the outcome reported immediately back to the user. The

potential impact for the dialog systems is that tasks conventionally

performed in a system turn can now be carried out in

the midst of a user turn, thereby presenting a significant departure

from the conventional turn-taking. To assess the

efficacy of such highly interactive interface, more user studies

are undoubtedly needed. This paper demonstrates how

SALT can be employed to facilitate such studies.
