Validation of language resources in TC-STAR

In TC-STAR a variety of Language Resources (LR) are being produced. In this contribution we address the validation of resources that were created and used for the second Evaluation Campaign of the project. For the three types of topics covered by the project (ASR, SLT, TTS) the validation of both development and evaluation sets is described. For each type we successively address the description of the data, the validation procedures and the validation results. It is concluded that validation constitutes an important and useful element in the production of high quality TC-STAR language resources.
