HABLA

Benchmark-ready packaging of HABLA — HABLA: A Dataset of Latin American Spanish Accents for Voice Anti-spoofing (Tamayo Flórez, Manrique & Pereira Nunes, Interspeech 2023). The first voice anti-spoofing collection in Spanish, covering five Latin-American accents (Argentina, Chile, Colombia, Peru, Venezuela).

Overview

The task is binary classification: bonafide (genuine human Spanish speech) vs. spoof (synthetic / converted speech). Bonafide audio is real Latin-American Spanish; spoof audio is produced by several generators:

• CycleGAN, Diff(usion), StarGAN — voice-conversion across accent pairs (e.g. Argentina-Chile).
• TTS — text-to-speech.
• TTS-Diff, TTS-StarGAN — TTS output further passed through a Diff / StarGAN voice-conversion stage (the TTS-VC cascade).

Labels and the evaluation protocol are unmodified; audio is shipped as the verbatim source 16 kHz mono PCM WAV (no re-encode — a whole-set decode probe confirmed every clip is already 16 kHz mono).

Schema

Column	Type	Description
path	string	source-relative path of the clip, unique
audio	Audio(16000)	16 kHz mono
label	ClassLabel	"bonafide" (0) / "spoof" (1)
notes	string	JSON: utterance_id, speaker_id, system, source_subdir

utterance_id is the on-disk filename stem (globally unique across all six dirs). system is the spoof generator (CycleGAN / Diff / StarGAN / TTS / TTS-Diff / TTS-StarGAN) or real for bonafide.

notes example:

{"utterance_id": "CycleGAN-arf_00295_00101634363-arf_02121_002402", "speaker_id": "arf_00295", "system": "CycleGAN", "source_subdir": "CycleGAN/Argentina-Argentina/arf_00295-arf_02121"}
