Bartosz Stolinski, Bartosz Ziółko · 2015
Three possible methods of detecting recorded speech were analysed and tested according to their applicability in the field of voicemail detection in this paper. Methods chosen for testing were: transmission channel characteristics extraction with PFCC, recorded speech detection with trained pattern classifier, differences in transmission channels and speech recognition. Most of the tests gave results credible enough to confirm methods' usefulness in the field of voicemail detection. Suggestions of implementation possibilities and parameters of each method and possible trends of further studies were also included.
