Pluricentric languages (PLCLs) are a common type among the languages of the world. Presently 43 languages have been identified to belong to this category. These languages are being used in at least two nations, having an official function there and forming national varieties of their own with specific linguistic and pragmatic features. In addition to the variation on the level of national standard varieties, there is also so called “second level variation” on a regional and local level that is often being used in diglossic speech situations where code switching is a salient feature with two or more varieties being used within the same utterance. The amount of linguistic variation in pluricentric languages is considerable and poses a challenge for speech recognition in particular and human language technology in general.

The motivation for this sattelite workshop is the observation that pluricentric languages have mainly been described linguistically but not sufficiently been dealt with in the field of speech technology. This is particularly the case with the so-called “non-dominant varieties”. This sattelite workshop focuses on PLCLs specific topics such as the development of methods for creating resources (e.g., how to elicitate code switching, how to develop annotation tools that are variant-independent), novel statistical methods for speech and language technology needed to deal with small data sets (e.g., OOV handling in language modeling), speech synthesis for non-dominant varieties, and how to use speech technology to aid quantitative sociolinguistic studies.

Submission Guidelines

All abstracts must be original and not simultaneously submitted to another journal or conference. We ask for Abstracts of 400-600 words submitted by April 5, 2019. They will be peer-reviewed and published as Book of Abstracts online. At the workshop, all presentations will be oral and of 15 min. length.

A special issue in Speech Communication will be later published containing peer-reviewed substantially extended versions of the abstracts accepted to the conference.
