DialogDesigner
Other tools than DialogDesigner exist which are meant to support the design and evaluation of spoken dialogue systems and which support Wizard of Oz (WOZ) simulation. Two such tools are Suede and the WOZ tool developed by Richard Breuer. IVR tools extended with recognition facilities, such as HotVoice from Dolphin, may also be seen as related work, as may spoken dialogue platforms like SpeechMania which was produced by Philips. The table below gives a rough comparison of which features are included in the mentioned tools.
