speakrs (maherr fork)

A thin CLI wrapper around avencera/speakrs 0.3.1, plus a vendored copy of the library patched with an ort::MIGraphX execution-provider mode for AMD GPUs.

What this is

• Root crate: speakrs-cli — produces the speakrs-cli binary used by Witness. Wraps the library's diarization pipeline, handles CLI I/O, writes RTTM or JSON.
• vendor/speakrs/: speakrs 0.3.1 (Apache-2.0, Praveen Perera), vendored via cargo vendor and patched to add the migraphx Cargo feature gating an ExecutionMode::MiGraphX path. See src/inference/embedding/session.rs for with_migraphx_mode().
• src/bin/ort-migraphx-repro.rs: minimal reproducer for the _dl_fini heap-corruption race described in the blog post. Not built by default.

Build

cargo build --release --bin speakrs-cli

Requires ORT 2.0.0-rc.12 with MIGraphX support — for RDNA 4, that means maherr/onnxruntime-migraphx-rdna4's patched build. The install script in that repo runs this cargo build automatically.

Why this isn't a regular git-history fork

I vendored speakrs with cargo vendor rather than forking the repo, because I only needed one feature (migraphx) gated on conditionally-compiled code paths — not an invasive rewrite. Upstream git history is lost, but vendor/speakrs/Cargo.toml.orig and vendor/speakrs/LICENSE preserve attribution and license. If a cleaner upstream PR lands, I'd switch to that.
