Structure

  • wav directory contains wav files (16 kHz, mono channel), which are classified to train, dev, and test.
  • txt directory contains json files split to train, dev, and test.
    • Each json file is a list of scenarios.
    • Each scenario contains:
      • id, tag, title, and original_language, which are identical to the ones of the BSD corpus, and conversation
    • conversation is a list of utterances. Each utterance contains:
      • no, ja_speaker, en_speaker, ja_sentence, en_sentence that are identical to the ones of the BSD corpus
      • ja_spkid and en_spkid that show speaker IDs consistent throughout the conversation
      • ja_wav and en_wav that show the wavfile names located in the wav diretory
      • ja_spk_gender and en_spk_gender that show the gender of the speaker of the corresponding wav file
      • ja_spk_prefecture and en_spk_state that show where the speaker come from

Notes

  • Gender is one of "M" or "F".

  • Speakers are different if speaker ID is different. For example, if a conversation is spoken by two speakers taking turns, there would be 4 speakers (2 Japanese speakers and 2 English speakers). However, it's possible that speakers with different speaker ID is actually spoken by the same person because of the way audio is collected.

  • Gender information of audio does not necessarily match with the one inferrable from text. For example, even if the en_speaker is "Mr. Sam Lee", the audio may contain female voice. This is because no explicit gender information is given in the original BSD corpus.

  • Japanese speech is collected from Japanese speakers who are from Japan.

    • ja_spk_prefecture is one of the 47 prefectures or "不明" (unknown).
      • Prefectures that ends with "県" or "府" does not contain those characters (e.g., "神奈川", "京都").
      • Tokyo is "東京" without "都".
      • Hokkaido is "北海道".

  • English speech is collected from English speakers who are from the US.

    • en_spk is one of the 50 states, written in postal abbreviation.

Furthermore, we consider context to be an important aspect that needs to be addressed in this task and propose two ways of utilizing context, namely monolingual context and bilingual context. We conduct cascaded speech translation experiments using Whisper and mBART, and show that bilingual context performs better in our settings.",
