Synthetic Voice Systems // VL-01

Separate the voice from the way it moves.

The project tests whether vocal identity, articulation, timing, prosody and presence can be treated as separable systems rather than one inseparable finished recording.

CANONICAL TEST PHRASE “The rain in Spain falls mainly on the plain.” Same phrase across stages so the processing — not the script — is what changes.

What changes here

Preserve articulation before changing identity.

The donor supplies intelligible speech, consonant placement and timing. At this point the voice is useful as an articulation source, not as the target identity.

PUBLIC AUDIO SAMPLE The interface is live; deliberately exported public-safe comparison clips will populate these slots. Private source voices are not published.
Synthesis branch // R1 → R2.2

Build speech from rules.

An earlier branch explored self-contained browser synthesis: mathematical excitation, phoneme targets, formant motion, source/filter rendering and a hybrid soft-tract renderer.

R1 / waveform + formants R2 / source-filter R2.1 / tube tract R2.2 / hybrid soft tract
No pretrained voice model required for this branch.
Empirical branch // V2 → V4

Recover movement rules.

Analysis experiments progressively moved from broad empirical voice structure toward speech landmarks and presence, using observed behaviour to derive numerical rules rather than retaining source recordings.

V2 / empirical profile V3 / landmarks V4 / presence
Goal: keep rules and invariants, discard source audio.
Next research branch

Speech motion model

R3 still reshapes a finished donor. The next question is more fundamental: can speech be represented as separate vocal identity/body, articulation/timing and prosody/delivery layers, then recombined without inheriting the donor as a finished voice?

IDENTITY / BODYWho is speaking?
ARTICULATION / TIMINGHow are sounds formed?
PROSODY / DELIVERYHow does the utterance move?

Public demo rule

Show the experiment, not the private source material.

Only deliberately created showcase clips belong here. Private source voices, personal audio and private creative context remain outside the public site. Stage descriptions expose the engineering idea without exposing the material used during private development.
