Data Fields

Logical access (LA):

  • speaker_id: LA_****, a 4-digit speaker ID
  • audio_file_name: name of the audio file
  • audio: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: dataset[0]["audio"] the audio file is automatically decoded and resampled to dataset.features["audio"].sampling_rate. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the "audio" column, i.e. dataset[0]["audio"] should always be preferred over dataset["audio"][0].
  • system_id: ID of the speech spoofing system (A01 - A19), or, for bonafide speech SYSTEM-ID is left blank ('-')
  • key: 'bonafide' for genuine speech, or, 'spoof' for spoofing speech

Physical access (PA):

  • speaker_id: PA_****, a 4-digit speaker ID

  • audio_file_name: name of the audio file

  • audio: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: dataset[0]["audio"] the audio file is automatically decoded and resampled to dataset.features["audio"].sampling_rate. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the "audio" column, i.e. dataset[0]["audio"] should always be preferred over dataset["audio"][0].

  • environment_id: a triplet (S,R,D_s), which take one letter in the set {a,b,c} as categorical value, defined as

    a b c
    S: Room size (square meters) 2-5 5-10 10-20
    R: T60 (ms) 50-200 200-600 600-1000
    D_s: Talker-to-ASV distance (cm) 10-50 50-100 100-150
  • attack_id: a duple (D_a,Q), which take one letter in the set {A,B,C} as categorical value, defined as

    A B C
    Z: Attacker-to-talker distance (cm) 10-50 50-100 > 100
    Q: Replay device quality perfect high low

    for bonafide speech, attack_id is left blank ('-')

  • key: 'bonafide' for genuine speech, or, 'spoof' for spoofing speech
