l2-arctic-manual-v5.0-16k

This dataset is a prepared derivative of L2-ARCTIC v5.0 that keeps only the manually annotated material and converts the audio to 16 kHz mono FLAC.

It is designed to plug into the current peacock-asr training code, which can consume a Hugging Face dataset with audio plus phonemes.

Included splits

• —train: 1800 rows, 1.84 hours
• —validation: 899 rows, 0.94 hours
• —test: 900 rows, 0.88 hours
• —suitcase: 22 rows, 0.44 hours

The scripted subset uses the common 12/6/6 speaker partition:

• —train: remaining scripted speakers
• —validation: MBMPS, NCC, SVBI, THV, YBAA, YDCK
• —test: NJS, TLV, TNI, TXHC, YKWK, ZHAA
• —suitcase: spontaneous story-retelling subset from the separate suitcase corpus

Columns

• —audio: 16000 Hz mono FLAC audio
• —phonemes: perceived phone sequence aligned to the audio
• —canonical_phonemes: reference phone sequence
• —manual_events: full interval-level manual annotations with raw and normalized labels
• —transcript, speaker_id, gender, native_language, subset
• —num_substitutions, num_additions, num_deletions

phonemes[*].phoneme is normalized toward the current peacock-asr 39-phone vocabulary. Silence/pause intervals and opaque err labels are excluded from that training-facing sequence, but preserved in manual_events.
