Speech-biometric dialect analysis in asylum processing
Germany's migration office piloted dialect analysis with an approximately 20% error rate in 2017
Problem
The migration office sought additional indications of an asylum applicant's country or region of origin. Dialect analysis was intended to supplement that assessment.
Approach
The office and a supplier adapted speech-biometric software to analyse speech against language models. By December 2017, an expanded pilot covered arrival centres and branch offices. It distinguished Arabic dialects and operated outside the formal asylum hearing as a supplementary indication of origin.
Results
Takeaway
The reported error rate limited the weight that dialect classification could carry. Nationwide operation remained a conditional plan in the 2017 account.
