Speaker-Diarization-Instructions
Convert diarization dataset from https://huggingface.co/diarizers-community into speech instructions dataset and chunk max to 30 seconds because most of speech encoder use for LLM come from Whisper Encoder.
We highly recommend to not include AMI test set from both AMI-IHM and AMI-SDM in training set to prevent contamination. This dataset supposely to become a speech diarization benchmark.

Tamil-English Code-Mixed Podcast Diarization Dataset
Dataset Summary
This dataset contains long-form Tamil-English code-mixed podcast recordings
annotated for speaker diarization research. The recordings consist of natural
conversational speech with multiple speakers and realistic acoustic conditions,
making the dataset suitable for evaluating diarization pipelines in
real-world scenarios.
The dataset is intended to support research in:

Dataset Card — Spjallrómur AB Diarization Test Set
Dataset Description
Spjallrómur AB Diarization Test Set is a curated test set for
speaker diarization evaluation on conversational Icelandic speech. It is
derived from the Spjallrómur 26.03
corpus by merging the two separate recording channels (A and B) into single
mixed-audio files, producing a realistic diarization benchmark with known
ground-truth speaker turns.
The test set was compiled as part of the Almannarómur… See the full description on the dataset page: https://huggingface.co/datasets/palli23/Spjallromur-AB-Diarization-test.ami_for_diarizationlmdanish-diarization-bench
Danish Diarization Benchmark (Synthetic) — v2
A 3996-row synthetic speaker-diarization benchmark in Danish, built by mixing
single-speaker utterances from
syvai/danish-asr-unified
into multi-speaker recordings.
What changed in v2 (2026-05-18)
Per-segment text — each entry in segments now carries its text field directly. The redundant parallel texts column has been removed. Old consumers that joined segments[i] with texts[i] should switch to segments[i]["text"].

This dataset combines six independently aligned source archives. Each row embeds its selected MP3 in the audio Parquet column. SBPN-derived word timestamps are observational and do not control chunk edges or the Demucs vote. Accepted hard-word verbalizations are projected back to the original written forms; pronunciation_alignment_dictionary_json records the winning spoken form.
