The approach is based on hierarchical processing where equally-sampled posterior probabilities of phoneme classes are estimated first, followed by matched filtering that yields non-equally spaced values, one for each phoneme, indicating confidences of underlying phoneme being present. The target keyword is indicated by a particular sequence of high-confidence phonemes.}, pdf = {https://publications.idiap.ch/attachments/reports/2005/rr05-41.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2005/rr05-41.ps.gz}, ipdmembership={speech}, }
