MOSS-Transcribe-Diarize-Whisper-Encoder

The audio encoder of OpenMOSS-Team/MOSS-Transcribe-Diarize, repackaged as a standard transformers Whisper encoder (WhisperModel config: dmodel 1024, 24 layers, 80 mel bins, 307 M parameters) so that it can feed a frozen LLM through a DuplexJev connector. The weights are those of the original model's `whisperencoder, unchanged (model.encoder.*); the tokenizer files are copied from openai/whisper-small` only so that the Whisper processor loads. Reloading gives outputs identical to the original encoder (max difference 0).

In a linear probe on mean-pooled last-layer states (3,000 train / 800 test clips) it separates speaker gender at 99.0% and four-way emotion at 88.2%, close to Qwen3-ASR-0.6B (99.2 / 90.9) and well above Whisper-large-v3-turbo (88.4 / 82.8).

Used by the DuplexJev-B[-Para]-MOSS-Transcribe-* connectors; Decider.from_pretrained("adventists-ai/DuplexJev-...") fetches it automatically. Source: github.com/adventists-ai/duplexjev.
