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
