ThaiMix (https://arxiv.org/abs/2512.18834) is a Thai pretraining corpus containing 70 billion tokens across 81 million documents (in the minhash subset). Rather than scraping the web again, ThaiMix combines five publicly available Thai datasets, applies Thai-specific quality filtering, and performs cross-dataset deduplication.

Thai Aligner Bench
🚧 Development in progress.
How accurately can a forced aligner place Thai token and word boundaries in
speech? This is a self-contained benchmark: one Python file
(aligner_bench.py) plus 1,572 clips of Thai speech with frame-exact timing
ground truth. No Thai NLP stack or other code is needed — just
numpy soundfile torch torchaudio transformers.
The ground truth is what makes the dataset useful: the audio was rendered by a
TTS model whose duration predictor… See the full description on the dataset page: https://huggingface.co/datasets/wayu-ai/thai-aligner-bench.MMMU-Thai

Thai Contextual-Biasing ASR Benchmark
TL;DR
Does your Thai ASR system actually use the context you give it (e.g., a list of names, custom words from your own dictionary) — and does it hallucinate when the context is irrelevant?
Each utterance comes with a bias list: entity strings (brands, person names,
places) that may or may not be spoken in the audio, written the way a real Thai user
would write them — one list, mixed Thai and Latin script. A good system does… See the full description on the dataset page: https://huggingface.co/datasets/wayu-ai/thai-contextasr-bench.thaillm-leaderboard-datasetthaisumThaiSum is a large-scale corpus for Thai text summarization obtained from several online news websites namely Thairath,
