NetJets surname phonetic G2P evaluation

Source: Namecoach/netjets-name-asr, Hub revision dd9ca45ff76c1cf5017d03bbd3558f625420928f, train split.

This benchmark presents a written surname grapheme and expects one of the observed custom written phonetic spellings for that surname. The phonetic strings are retained exactly after outer whitespace trimming; capitalization encodes stress and hyphens/parentheses are meaningful notation.

Files

• data/eval-00000-of-00001.parquet: viewer-backed eval table with grapheme and phonetic as the first two columns.
• rows.jsonl: one row per retained source occurrence. Do not deduplicate this file: its repeated rows preserve the source pronunciation frequency.
• metadata/groups.jsonl.txt: one row per grapheme with its observed variant counts and probabilities. Use this for distributional evaluation and allowed-output validation.
• metadata/excluded.jsonl.txt: source rows that could not be mapped to one auditable grapheme token, with the reason and candidate scores.
• manifest.json: source hash, counts, extraction policy, and frequency policy.

Row contract

Each row contains grapheme, phonetic, a stable source id, source provenance, and alignment metadata. A prediction is valid only if it exactly equals one of the phonetic variants listed for that row's grapheme_key in metadata/groups.jsonl.txt.

Alignment policy

The dataset's name field is an ASR/spoken reconstruction and can contain extra or missing tokens, so the final whitespace token is not always the labeled surname. The builder uses a documented token-to-phonetic character-similarity heuristic with a surname prior, removes common suffixes such as Jr/III, and excludes ambiguous or unalignable rows instead of fabricating grapheme labels.

Counts

• Source rows: 36,704
• Retained eval occurrences: 35,891
• Unique graphemes: 15,938
• Unique grapheme/phonetic pairs: 27,644
• Excluded rows: 813
