Data Fields
Logical access (LA):
speaker_id
:LA_****
, a 4-digit speaker IDaudio_file_name
: name of the audio fileaudio
: 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 todataset.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 overdataset["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 IDaudio_file_name
: name of the audio fileaudio
: 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 todataset.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 overdataset["audio"][0]
.environment_id
: a triplet (S,R,D_s), which take one letter in the set {a,b,c} as categorical value, defined asa 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 asA 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
