The listener in the AAC reference app ("Hearing your partner") turns what
someone says to the person into text, on their device, with onnxruntime-web.
The app serves the runtime from its own site, under
vendor/onnxruntime-web-<version>-<revision>/, put there by
third_party/onnxruntime-web/vendor.sh. When someone downloads the listener,
the app copies the runtime files their browser needs into their model store
and runs them from there, in a worker on their device, on its graphics chip.
Nothing heard is recorded or sent anywhere.

ONNX Runtime Web (onnxruntime-web, the version in the directory name), by
Microsoft Corporation.
  ort.jspi.bundle.min.mjs and ort-wasm-simd-threaded.jspi.wasm: unchanged
  from the npm package. They are Microsoft's prebuilt WebAssembly build of
  ONNX Runtime with its WebGPU execution provider, for browsers with
  JavaScript Promise Integration (the listener is offered only in those).

asr-worker.js is the app's own worker (worker.js beside vendor.sh), part of
the AAC reference app and under its licence (Apache-2.0). It drives the
runtime; it is not part of ONNX Runtime.

The speech model the runtime runs (NVIDIA Nemotron 3.5 ASR Streaming 0.6B,
OpenMDW-1.1) and the voice activity detector (Silero VAD, MIT) are not part of
this directory and are not covered by LICENSE.txt. The app publishes them
separately, with their own licences and attribution, in the listener's
catalogue (Settings > Hearing your partner).
