about
nx_tts_formant.nx -- R2.0 of the sovereign VOICE-YOU-CAN-HEAR (embodiment census R2, hardware-up rung 1).
Classical source-filter FORMANT synthesis, zero ML: a glottal impulse train (pitch F0) cascaded through
3 formant resonators (2-pole, coeffs from the verified nx_f32_cos/nx_f32_exp) shapes it into vowel timbre;
a phoneme sequence (a->i, "ai") is synthesized, normalized, and written as a real 16-bit PCM WAV she can PLAY.
Robotic but INTELLIGIBLE and fully sovereign -- the audio-out path that serves BOTH bodies (digital + robot
TTS). Later rungs: glottal pulse shape, consonants, G2P text->phonemes, then neural quality. license_tier: ORIGINAL expect_exit: 0
