Glottal-Synchronous Speech Processing (2010)
Abstract / truncated to 115 words
Glottal-synchronous speech processing is a field of speech science where the pseudoperiodicity of voiced speech is exploited. Traditionally, speech processing involves segmenting and processing short speech frames of predefined length; this may fail to exploit the inherent periodic structure of voiced speech which glottal-synchronous speech frames have the potential to harness. Glottal-synchronous frames are often derived from the glottal closure instants (GCIs) and glottal opening instants (GOIs). The SIGMA algorithm was developed for the detection of GCIs and GOIs from the Electroglottograph signal with a measured accuracy of up to 99.59%. For GCI and GOI detection from speech signals, the YAGA algorithm provides a measured accuracy of up to 99.84%. Multichannel speech-based approaches are shown ... toggle 13 keywordsspeech processing – EGG – SIGMA – glottal closure – glottal opening – YAGA – dereverberation – spatio-temporal averaging – PSOLA – speech coding – speaker id – data-driven voice source modelling – artificial bandwidth extension.
