Checkpoint Selection

Notebook outputs show that validation checkpoint comparison selected checkpoint-2000 by normalized corpus WER.

Checkpoint	Validation WER	Validation CER	Eval loss
`checkpoint-2000`	`0.674941`	`0.365374`	`0.561479`

A later exploratory notebook cell evaluated checkpoint-1250 after the upload. That post-hoc test result should not be interpreted as the uploaded best checkpoint.

Notebook-Recovered Test Artifact

The notebook contains test metrics for the later post-hoc checkpoint-1250 evaluation:

Checkpoint	Test WER	Test CER	Avg WER capped	Avg CER capped
`checkpoint-1250`	`0.750161`	`0.492839`	`0.558925`	`0.327015`

Per-Speaker Breakdown

These per-speaker aggregates come from the notebook-displayed grouped analysis for the recovered post-hoc checkpoint-1250 test artifact.

Speaker	Severity	Disorder	Etiology	N	Mean WER	Mean CER	Median WER	Median CER
`UG057`	Severe (frequent breakdowns)	Voice disorder	Acquired hearing impairment	105	`0.7087`	`0.4463`	`0.8286`	`0.4842`
`UG042`	Severe (frequent breakdowns)	Stuttering (Disfluency Disorders)	Developmental	85	`0.6138`	`0.2924`	`0.6667`	`0.2381`
`UG058`	Severe (frequent breakdowns)	Stuttering (Disfluency Disorders)	Developmental	125	`0.5332`	`0.3034`	`0.5714`	`0.2571`
`UG052`	Moderate (requires effort to understand)	Stuttering (Disfluency Disorders)	Developmental	79	`0.5293`	`0.2623`	`0.5000`	`0.2097`
`UG021`	Moderate (requires effort to understand)	Articulation Disorders	Structural presence of akloglosia, simply tong...	91	`0.5230`	`0.2498`	`0.5517`	`0.1929`
`UG022`	Mild (easily understood with minimal effort)	Articulation Disorders	Developmental	117	`0.4837`	`0.2311`	`0.5000`	`0.1642`
`UG036`	Moderate (requires effort to understand)	Dysarthria	Cerebral Palsy	177	`0.4481`	`0.2001`	`0.4375`	`0.1429`
`UG014`	Mild (easily understood with minimal effort)	Stuttering (Disfluency Disorders)	Idiopathic	149	`0.3728`	`0.1271`	`0.3333`	`0.0645`
`UG001`	Mild (easily understood with minimal effort)	Dysarthria	Cerebral palsy - cerebral malaria	99	`0.3573`	`0.1542`	`0.3636`	`0.1399`

Evaluation Notes

The model card is reconstructed from executed notebook outputs and extracted local summaries. Full per-utterance prediction files were referenced in notebook outputs as remote /workspace/... artifact paths, but were not embedded in the notebook JSON available locally.
