This paper presents a framework for asynchronous dialogue systems. It is used in developing text-based dialogue systems. The framework features web-based asynchronous turn management and AI-assisted live agent chat. Some other features are also briefly covered in this paper (a language independent solution for spell checking the user input, a language independent solution for the word-order problem, semantic resolution and a web-based interface for WOZ data collection). The exploitation of the asynchronous communication pattern has improved the communication style of the user which has resulted in decreased number or single word utterances. Higher word count per utterance is important when performing shallow language analysis without complete semantic understanding. The framework is currently tailored for Estonian language, yet most of its features and modules are language independent.
