Welcome to the wiki for the BYU Department of Linguistics' PSST Research Group. Here you will find information about our past, ongoing, and future activities.

PSST is an acronym for "Pedagogical Software and Speech Technology". The principal focus of our group is to explore and expand the use of speech technology in language learning. We work with existing speech technologies, examine pedagogical needs for language learning, and design and develop improved technological tools (including speech applications) for language learning and testing.

Besides this principal focus, our interests have expanded to include such areas as: automatic assessment of oral language proficiency, simultaneous interpreter training, text-based essay scoring, speech interfaces to robots, vocal attractiveness, and using speech recognition in animal communication.

Our old project website is now obsolete but most of the content has been carried over to this wiki.



The following sections of this main page will be phased out as of 10.1.11:

"If you are a volunteer English EI grader, follow these links to our grading website and please read our Updated Grading FAQS. previously grading FAQS

If you are working on Japanese EI grading please follow this link to grade Japanese Grader"

A new subsection entitled "Grading" can be found below with all pertinent information, as human grading is no longer a top priority.


Meetings are currently held in 4068 JFSB (Linguistics Conference Room) on Mondays from 3:00 to 4:00 p.m. (updated 22 September 2011). Meetings are open to all who are interested.

  • Note: We will set a meeting time on a per term / per semester basis

Here are links to the various publications (Bibliography:Publications), presentations (Bibliography:Presentations), theses (Bibliography:Theses), and undergraduate research projects (Bibliography:ORCA projects) that our project has produced. In some cases the items listed might duplicate items listed in other project wikis (e.g. the NL-Soar or NLP wiki) where interests and efforts overlap.

Here is a link to others' work on elicited imitation and other related areas (Bibliography:EI_(Public)).
