Pitch excitation, e.g. pitch synchronous innovation CELP [PSI-CELP]

Introduced: January 2013

Full Title

Full titles differ between systems:

IPC:

Speech or audio signal analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis > using predictive techniques > Determination or coding of the excitation function; Determination or coding of the long-term prediction parameters > the excitation function being a code excitation, e.g. in code excited linear prediction [CELP] vocoders > Pitch excitation, e.g. pitch synchronous innovation CELP [PSI-CELP]

CPC:

Speech or audio signals analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis (in musical instruments G10H) > using predictive techniques > Determination or coding of the excitation function; Determination or coding of the long-term prediction parameters > the excitation function being a code excitation, e.g. in code excited linear prediction [CELP] vocoders > Pitch excitation, e.g. pitch synchronous innovation CELP [PSI-CELP]

No child classifications to compare. This is a leaf node in both IPC and CPC.
