For 10 points, all of these strategies deal with the synthesis or analysis of what human capability produce meaningful vocal utterances?
Its quality is measured in MOS ["moss'].  One device that creates it is called GLOVE and uses thirty-seven control parameters; another device to create it is named after Klatt and uses only nineteen.  One algorithm for producing it is known by the acronym PSOLA in which the OLA stands for "overlap and add".  Delta modulation, a variant on differential PCM, can be used to digitally code it, but more prevalent is the use of a codebook in CELP ["selp"], which is the primary strategy used in cellular phone processors.
