On parameter filtering in continuous subword-unit-based speech recognition
(H. TIMOTHY BRUMMELL, WILLIAM IDSARDI CITATION DELAWARE, NEW CASTLE, DELAWARE, 1996)
Text en actes de congrés
Accés obertSimple IIR or FIR filters have been widely used in isolated or connected word recognition tasks to filter the time sequence of speech spectral parameters, since, despite their simplicity, they significantly improve recognition ... -
Operators to calculate the derivative of digital signals
(2013)
Comunicació de congrés
Accés obertThis paper presents an FIR operator with a very low computational cost for calculating the first derivative of discrete band-limited signals. The basic idea is to use cubic spline polynomials for interpolating among the ... -
