DiscoPhon is a multilingual benchmark evaluating unsupervised phoneme discovery from discrete speech units. Given only 10 hours of speech in an unseen language, models must produce discrete units that map to a predefined phoneme inventory.
Getting started
DiscoPhon requires Python ≥ 3.12.
- Install this package:
pip install discophon # core: phoneme discovery evaluation pip install "discophon[prepare]" # adds the data download and preparation pip install "discophon[abx]" # adds ABX discriminability (fastabx) pip install "discophon[baselines]" # adds the baseline models
Only thebaselinesextra has a system dependency: FFmpeg, required bytorchcodecto read audio. - Follow the tutorials to download data, evaluate models, and prepare your submission.
- Current leaderboard.
