# digital-health-clinical-asr-finetune Skill for running stock NeMo SFT on Parakeet TDT v2 and measuring post-training KER.

It relies on `nvidia/parakeet-tdt-0.6b-v2` as the recommended base model. No custom adapter logic is used because adapter-mixin paths on TDT decoders generate 72 NaN tensors at any learning rate. Fine-tuning `nvidia/nemotron-speech-streaming-en-0.6b` is also prohibited due to an immediate validation collapse. Execution requires a manifest with at least 100 rows and 5 rows per priority entity category. You need a CUDA host with 24 GB VRAM for standard runs or 16 GB with batch size 4. If a local GPU is unavailable, the skill directs users to a Brev L40S 48 GB instance. Running cycle N+1 offline evaluation and NIM deployment requires `NVIDIA_API_KEY`. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill digital-health-clinical-asr-finetune -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/digital-health-clinical-asr-finetune/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/digital-health-clinical-asr-finetune/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill digital-health-clinical-asr-finetune -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/digital-health-clinical-asr-finetune/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill digital-health-clinical-asr-finetune -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/digital-health-clinical-asr-finetune/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install NVIDIA/skills digital-health-clinical-asr-finetune ``` 2. **Manually: put the files in place** - File: `.github/skills/digital-health-clinical-asr-finetune/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill digital-health-clinical-asr-finetune -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/NVIDIA/skills --path skills/digital-health-clinical-asr-finetune ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/digital-health-clinical-asr-finetune/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add NVIDIA/skills --skill digital-health-clinical-asr-finetune -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/digital-health-clinical-asr-finetune/SKILL.md ## When to use it - fine-tune Parakeet TDT v2 on clinical vocabulary - reduce priority KER for medication and procedure names - run stock NeMo SFT inside the official container - perform offline cycle N+1 re-evaluation ## Example prompts - Fine-tune ASR on my clinical vocabulary - We have a KER of 0.4, run SFT on Parakeet TDT - Compare cycle 1 vs cycle 2 KER ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

Answer from this file; defer to the reference only when a hyperparameter rationale or Brev SKU detail is specifically asked. You are the **adapt-and-measure** stage. The user arrives from `/digital-health-clinical-asr-eval` with a manifest, a baseline KER number, and the decision-tree's recommendation that fine-tuning is worth the GPU time. You run stock NeMo SFT, do an offline cycle N+1 re-eval to **measure that the loop closed**, and optionally hand the resulting `.nemo` to `/riva-asr-custom` for production serving. **The cycle KER from offline eval is the measurement that closes the loop.** Riva NIM deploy validates serving (latency, streaming, scale), not model quality. > **Empirically verified on the reference manifest** (39 rows, Parakeet TDT v2): > Baseline KER **0.513** → after 3 epochs of stock SFT: **0.128** (-75% relative). ``` END THIRD-PARTY FILE 7ac6e113e762d353 The third-party file has ended.
