vansprouts - media - ecotech - stuffhyperdiva drives the apple macintalk3 text-to-speech synthesizer in a precise harmonic+phonetic mode. the hyperdiva stack runs with hypercard or hypercard player 2.41 in mac-os 7.55 thru 9.22 (but not in mac-os x classic, due to bugs in both PHON and TUNE modes of the mac-os x speech synthesizer).
for example, below is the first published version of "meta metta" (2004), a quicktime movie showing my original ipa phonetic input text, which hyperdiva translates into the following code to drive the macintalk3 speech synthesizer... (notice the fractional midi notes and absolute zero modulation needed for perfect harmonics)
"meta metta tantra mantra, doobee-ooobee sophia sufi,
halleluia allahuya, kyrie yahweh allah om..."

for an (unexpected) experience of perfect harmony,
play these looping tracks at various intervals,
and let all sing together...
