TriStream-SVS
by CorX Labs · JamaicaA singing voice synthesis model that builds the source-filter theory of the human voice into its architecture as a hard constraint — pitch, timbre and breath texture run as three parallel encoder streams, combined only in a late fusion trunk. Generates at 24 kHz through rectified flow matching in roughly 32 sampling steps.

Where these numbers come from
Every score on this page is a published figure, taken from the model's own card, system card, technical report or release post, or from a public leaderboard. CorX Labs did not run these evaluations. Most are self-reported by the lab that built the model, which means they were produced under that lab's own choice of prompt, scaffold and number of attempts — so treat them as a starting point for a shortlist, not as a settled ranking.
A score someone other than the model's maker measured is marked Independent and names its measurer. Those are the stronger numbers on this page — an outside harness has no reason to flatter anyone — and there are not many of them.
Where a figure has not been published, the cell reads Not reported rather than an estimate. Nothing here is inferred, interpolated or guessed. Each model records the month its row was last checked. Full method and caveats.
