Unified Spoken Language Proficiency Assessment System

Language proficiency assessment is a common requirement for L2 speaker of English. There exists separate tools for spoken language assessment (SLA) to assess articulation in terms of pronunciation or oral fluency and for written language assessment (WLA) to assess language grammar and vocabulary. In this paper, we present a SLA system, called unified spoken language proficiency assessment (USLPA) system which is capable of assessing all aspects of language under one hood. From practical usage perspective, the language proficiency test should be easy to administer, should not be repetitive, should be automatic, should be short in duration, and should be reliable and robust in its assessment. The USLPA system has added benefits like removal of inherent human bias in the assessment process, allowing for a greater flexibility of assessment, and dynamic assessment instead of the same assessment tests for all candidates. In this paper, we propose an automatic end-to-end USLPA system to assess language proficiency.
