ESR6 : Alignment in human-machine spoken interaction

PhD fellowship


In the context of a dialogue game in which interlocutors describe objects to each other as part of a task, ESR6 will investigate the extent to which people align with each other and with a natural-language generation system, and how this impacts on task success. Starting from a simple referential communication game, in which objects may be referred to by means of different terms, ESR6 will move on to more naturalistic tasks such as determining a route through a complex environment. By manipulating the performance of the generation system (e.g., use of preferred vs dispreferred terms), we can determine what characteristics enhance alignment and task success. Manipulations will be directly relevant to alignment (e.g., whether the system always aligns with the person) as well as related to other aspects of the task (e.g., when and how often backchannels are used). ESR6 will also manipulate the human-likeness of the system.

Expected results:

Alignment is expected to lead to task success (a deceptively simple claim that needs carefully-controlled experimentation to test). Specifically, we expect a direct relationship between alignment of the generation system and alignment of participants (i.e., if the system aligns with you, you will tend to align with it). The effects of other manipulations are likely to be less direct; for example, backchannels may lead to more succinct descriptions and it may be easier to align on these descriptions.
