September 2025 – In google-research/mseb, delivered a unified MultiModalEncoder interface and migrated encoders to implement/consume it, enabling consistent cross-model encoding. Expanded benchmarking for encoders with byte-size metrics, compression ratio scores, and initial FLOPs tooling (Whisper PooledAudioEncoder). Refactored data/utilities: SimpleVoiceQuestionsDataset became standalone, added optional beam-format sound retrieval to task API, and improved packaging for pytest. Strengthened reliability with targeted fixes (run_task constructor, load_embeddings on missing files, and validation float enforcement) and removed outdated references/fields (HfHubPyError, deprecated weight). Broadened model registry and leaderboard coverage with hubert, wav2vec, wav2vec2 registration, a generic HuggingFace sound encoder, per-language svq clustering tasks, and updated MSEB results across components (hubert, wav2vec, spectrogram). This combination enhances encoding consistency, benchmarking fidelity, and research throughput while stabilizing test infra and data handling.
