English EN-X Code-Switching Main-Language

This dataset contains synthetic English-plus-one-language code-switching samples built from FLEURS.

Source data is google/fleurs at revision refs/convert/parquet, split test, resampled to 16000 Hz. The generator uses seed 42 and creates 50 mixed samples. Each mixed sample contains English and exactly one of Spanish, Portuguese, French, German, or Italian, sampled uniformly.

Each selected utterance is RMS-normalized to -20.0 dBFS before concatenation, with peak limiting at 0.99. The samples dataset stores those same normalized utterances.

The mixed dataset stores transcription_tagged as <lang><start:SS.ss>text<end:SS.ss>. The samples dataset stores each full utterance chunk separately and links it back with parent_id. The merged samples dataset concatenates contiguous chunks with the same language into one row per language segment.
