A first step towards a text-independent speaker verifi- cation Praat plug-in using Mistral/Alize tools
Jonas Lindh · 2009
Text-independent speaker verification can be a useful tool as a substitute for passwords or increased security check. The tool can also be used in forensic phonetic casework. A text-independent speaker verification Praat plug-in was created using tools from the open source Mistral/Alize toolkit. A gate keeper setup was created for 13 department employees and tested for verification. 2 different universal background models where trained and the same set tested and evaluated. The results show promising results and give implications for the usefulness of such a tool in research on voice quality.
