GTPhoneme

struct

GTPhoneme - Universal phoneme primitive represented as SDF in 3D acoustic space.
This is THE fundamental unit for speech recognition and synthesis.
SDF Distance = Phonetic similarity:
- Negative: Inside phoneme region (close match)
- Zero: Exact phoneme center
- Positive: Outside phoneme region (poor match)
MIL-SPEC: Struct-based, zero allocation, 64-byte cache line aligned.
GPU-Ready: Can be uploaded to compute shader for parallel ray marching.

GTPhoneme3DVocoder

static class

3DVocoder - The Speaker for GTPhoneme SDF fields.
Renders PhonemeAudioEnvelope SDF fields to audio samples via GPU-accelerated
formant synthesis. This is THE component that converts phoneme primitives
to actual sound waves.
Architecture:
Input: PhonemeAudioEnvelope (3D SDF field + temporal/voicing/intensity envelopes)
Processing: GPU ray marching through SDF field at each time step
Output: Audio samples (float[] PCM)
MIL-SPEC compliant: Zero allocation, real-time synthesis, GPU-ready.

Source: GTPhoneme.cs

Methods

SpeakPhoneme

float[] SpeakPhoneme ( PhonemeAudioEnvelope envelope, float sampleRate = 48000.0f )

Synthesize audio from single PhonemeAudioEnvelope via formant synthesis.
Uses SDF field to guide formant frequencies over time.
This is the core "Speaker" function - converts SDF field to sound waves.
PhonemeAudioEnvelope to render.
Audio sample rate (Hz).
Audio samples (float[] PCM).

Categories:
- Pulmonic Consonants (p, b, t, d, k, g, m, n, ŋ, f, v, s, z, ʃ, ʒ, h, l, r, w, j, etc.)
- Non-Pulmonic Consonants (Clicks: ʘ, ǀ, ǃ, ǂ, ǁ; Implosives: ɓ, ɗ, ɠ, ʛ)
- Vowels (i, e, ɛ, a, ɑ, ɔ, o, u, ɪ, ʊ, ə, ʌ, æ, etc.)

CharToLetter

EnglishLetter CharToLetter ( char c )

Convert character to EnglishLetter enum.

NaturalLanguageGeneration

static class

Natural Language Generation - Speech synthesis via SDF envelope interpolation.
Core API for converting UNLOCK glyphs → phonemes → audio.

Source: NaturalLanguageGeneration.cs

Methods

MapUNLOCKGlyphToPhoneme

GTPhoneme? MapUNLOCKGlyphToPhoneme ( UNLOCK.UNLOCKGlyph glyph )

Map UNLOCK glyph to GTPhoneme for speech synthesis.
Links linguistic energetics to acoustic phonetics.
Examples:
A (ANIMATE) → /eɪ/ (diphthong)
E (ENERGY) → /iː/ (long i)
C (CENTER) → /siː/ (see)
This is the bridge between UNLOCK linguistic analysis and
physics-based speech synthesis.
UNLOCK glyph to map.
Corresponding GTPhoneme (or null if no mapping).

NaturalLanguageUnderstanding

static class

Natural Language Understanding - Speech recognition via SDF phoneme matching.
Core API for converting audio → phonemes → UNLOCK glyphs → linguistic meaning.

Methods

RecognizePhonemeFromFormants

GTPhoneme? RecognizePhonemeFromFormants ( float f1_Hz, float f2_Hz, float f3_Hz, GTPhoneme[] phonemeDatabase, float maxDistance = 2.0f )

Recognize phoneme from formant frequencies via SDF ray marching.
Input: F1, F2, F3 formants extracted from audio (FFT window).
Output: Closest matching GTPhoneme (or null if no match within threshold).
This is GPU-parallelizable - all phonemes checked simultaneously.
Sub-millisecond recognition on typical hardware.
First formant frequency (Hz).
Second formant frequency (Hz).
Third formant frequency (Hz).
Array of GTPhoneme SDF fields to search.
Maximum SDF distance for valid match (default 2.0).
Closest matching GTPhoneme, or null if no match.

PhonemeAudioEnvelope

struct

PhonemeAudioEnvelope - SDF field representation for 3D vocoder network.
This is the elegant, GPU-friendly phoneme representation for synthesis.
Instead of raw waveforms or spectrograms, we represent phonemes as:
- 3D SDF field (formant space: F1 × F2 × F3)
- Temporal envelope (amplitude over time)
- Voicing envelope (voiced/voiceless transition)
- Intensity envelope (loudness over time)
This can be fed directly to a 3DVocoder Network for real-time synthesis.
