Abstract
Teager Energy Operator (TEO) proposed by Kaiser and Teager is based on a definition of energy required to generate the signal. TEO gives us the running estimate of energy as a function of amplitude and instantaneous frequency content of the signal. However, it considers three consecutive samples to calculate the energy estimate. In this paper, we suggests an alternative and generalized approach to TEO to calculate the instantaneous estimate of the energy where not only consecutive but other distant samples can also be incorporated in the calculation of running estimate of the energy and the number of samples taken to calculate energy can also be increased depending on our signal properties to better capture the energy content variations in the speech signal.
