We introduce a method to learn the distance used to compare acoustic frames, a crucial element for template matching approaches. The proposed algorithm estimates the distance from data, with the objective to produce a detector maximizing the Area Under the receiver operating Curve (AUC,',','), i.e. the standard evaluation measure for the keyword detection problem. The experiments performed over a large corpus, SpeechDatII, suggest that our model is effective compared to an HMM system, e.g. the proposed approach reaches 93.8\\% of averaged AUC compared to 87.9\\% for the HMM.}, pdf = {https://publications.idiap.ch/attachments/reports/2007/grangier_rr_07-15.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2007/grangier_rr_07-15.ps.gz}, ipdmembership={learning}, }
