# acoustic-phonetics SOURCE — the learned speech primitives, as INGESTIBLE DATA.
# NOT audio, NOT code: formant geometry of the phonemes, to be ingested via the
# ingest organ into the engram as a phoneme manifold. The render reads this
# geometry back from the engram; nothing is frozen in EL code.
#
# PROVENANCE (audited, per-field honesty — no invented numbers):
#  * The 10 MONOPHTHONG VOWEL formants F1/F2/F3 (IY,IH,EH,AE,AA,AO,UH,UW,AH,ER)
#    are the MEASURED adult-male means of Peterson & Barney (1952), JASA 24:175-184
#    — the canonical /hVd/ table, verified digit-for-digit vs CRAN phonTools::pb52.
#    These are real measured values.
#  * AX (schwa) F1/F2/F3 = neutral uniform-tube resonances (2n-1)*500 — a PHYSICS
#    value (Fant), not a P&B measurement.
#  * OW is a diphthong; its listed steady target is a conventional synthesis value,
#    not a P&B monophthong measurement.
#  * CONSONANT loci (M,N,NG,L,R,W,Y,Z,DH,V,S,F,HH) and ALL BANDWIDTHS (B1,B2,B3)
#    and dur/amp are STANDARD FORMANT-SYNTHESIS conventions (Klatt 1980, JASA 67:971
#    "Software for a cascade/parallel formant synthesizer") — engineering defaults,
#    NOT per-phoneme field measurements. Labeled as such, not attributed to P&B.
