Third-Party Notices

Dictee uses third-party software in two ways:

1. Bundled code: the speech runtime is compiled and statically linked into the Dictee binary.
2. Downloaded model artifacts: model weights are not bundled in the installer; the app fetches them on first run from Dictee R2 mirrors described by manifests/models.json.

Parakeet TDT 0.6b v3

The original NVIDIA NeMo model was exported to the sherpa-onnx offline transducer ONNX format and quantized to int8. Dictee redistributes and mirrors converted artifacts from:

The upstream Whisper Large v3 Turbo model was exported to the sherpa-onnx offline Whisper ONNX format and quantized to int8. Dictee redistributes and mirrors converted artifacts from:

Pipecat Smart Turn v3

Author/copyright: Pipecat AI.

Upstream model: pipecat-ai/smart-turn-v3, https://huggingface.co/pipecat-ai/smart-turn-v3.

License: BSD 2-Clause License, https://opensource.org/license/bsd-2-clause.

Dictee mirrors smart-turn-v3.2-cpu.onnx to stage-owned R2 and downloads it as a local static model asset per manifests/models.json. It is not bundled in the installer, is not a speech recognizer, and does not upload audio or transcripts.

sherpa-onnx

Author/copyright: the k2-fsa / sherpa-onnx authors.

Upstream: https://github.com/k2-fsa/sherpa-onnx.

License: Apache License 2.0, https://www.apache.org/licenses/LICENSE-2.0.

Dictee links the official sherpa-onnx Rust crate with the static feature, which compiles sherpa-onnx into the Dictee binary.

ONNX Runtime

Author/copyright: Microsoft Corporation.

Upstream: https://github.com/microsoft/onnxruntime.

License: MIT License, https://opensource.org/licenses/MIT.

The sherpa-onnx static feature bundles a prebuilt static ONNX Runtime library from the k2-fsa/sherpa-onnx release archives. It is linked into the Dictee binary; no separate dynamic library is shipped or signed.
