Odyssey 2010: The Speaker and Language Recognition Workshop
Brno, Czech Republic
The BKA voice comparison system SPES is designed for forensic examination of speech recordings. The classical GMM-UBM framework based on MAP adaptation as described by Reynolds et al. is extended by the generation of recording adapted background models (RABMs). We present results from experiments using real case data. These results show how the most critical properties of real case recordings such as duration, channel, and samples per speaker influence system performance.
