DIFF Subgroup
G10L 25/48 specially adapted for particular use
Introduced: January 2013
Full Title
Full titles differ between systems:
IPC:
Speech or voice analysis techniques not restricted to a single one of groups > specially adapted for particular use
CPC:
Speech or voice analysis techniques not restricted to a single one of groups G10L15/00 - G10L21/00 (muting semiconductor-based amplifiers when some special characteristics of a signal are sensed by a speech detector, e.g. sensing when no signal is present, H03G3/34) > specially adapted for particular use
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
IPC defines codes here since 2013.
