Sixth European Conference on Speech Communication and Technology
The number of telephone applications that use automatic speech recognition is increasing fast. At the same time the use of mobile telephones is rising at high speed. This causes a need for databases with speech recorded over the cellular network. When creating a mobile speech database a number of problems show up that are not an issue when creating a speech database of fixed network recordings. These problems have to do with different recording environments, different networks and handsets, speaker recruitment and distribution, and the transcription. In this paper, the problems are explained, a couple of possible solutions are given and our experiences with these solutions in our contributions to the creation of mobile speech databases are presented. Besides, ELRA’s position in the distribution of mobile speech databases is outlined.
