The preservation of under-resourced languages requires digital tools and resources shaped by and for their speakers. We present the first dedicated ASR resources for Puno Quechua (ISO 639-3: qxp): (1) the largest speech corpus for any single Quechua variety, consisting in 66 hours of recordings for scripted and spontaneous speech (including 36 hours of manually transcribed and validated data), collected via a participatory design campaign; (2) the first systematic ASR benchmark for Puno Quechua, evaluating state-of-the-art models and fine-tuning Whisper-base, wav2vec2-base, and XLS-R-300M, with and without continued pre-training (CPT); (3) an open release of all datasets and fine-tuned models.

### THE CONFERENCE WE KNOW AND WE WANT.
**COLING**, the International Conference on Computational Linguistics, is one of the premier conferences for the natural language processing and computational linguistics.

First established in 1965, the biennial COLING conference is held in diverse parts of the globe and attracts participants from both top-ranked research centers and emerging countries. Today, the most important developments in our field are taking place not only in universities and academic research institutes but also in industrial research departments including tech-startups. COLING provides opportunities for all these communities to showcase their exciting discovery.

In fall of 2022, COLING will be held in Gyeongju in a hybrid format. All participants can either present at the venue site or join virtually. As more people get vaccinated, we are happy to provide safer environments for our colleagues. We believe that COLING 2022 will be one of the conferences, free from the pandemic. The hybrid format gives presenters and sponsors a valuable opportunity to promote their companies in both an online and in-person venue. For the first time in a long time, customers can interact with their sponsor's products first-hand. The online venue, too, gives sponsors the chance to network with those unable to attend the in-person session.

The hybrid format ultimately lends itself to greater exposure for our sponsors: COLING2022 will let you reach more potential partners and customers than ever before!

workshop paper

It is my great pleasure and honor to welcome you to the 64th Annual Meeting of the Association for Computational Linguistics (ACL 2026), held in San Diego, California, USA, July 2–7, 2026. ACL 2026 continues our fields tradition of excellence in scholarship, innovation, and inclusivity, and I am deeply grateful to the many volunteers who have worked tirelessly to bring this event to life.

It is exciting to see the many developments in the field reflected at our conference, such as the advancement of large language models (born out of our community) into many application directions. This is not without challenges, partly due to unsolved problems, and partly due to misuse of the technology. All this is reflected well at ACL 2026. The conference also reflects that the field is not only about advancing technology, but also the science of fundamentally understanding language and how it is use by many different speaker communities.

In the context of real-world language technology applications, the language or variety in which a given text is written is often unknown or uncertain. Yet, this information is crucial in order to adequately select and apply appropriate models or resources. Language identification (LID), or the process of determining the language or variety of a text sample, is thus often an important fundamental task in natural language processing. LID can be particularly challenging when: (1) there are not many labeled texts for training; and (2) similar or related languages are involved, since these may share a number of surface-level features. In this paper, we present an LID system for Nahuatl, a group of closely-related language varieties spoken in Mexico and Central America. Nahuatl LID involves both of the aforementioned challenges: Nahuatl varieties can be quite similar, sharing morphemes and even many lexical items, and there is a relative paucity of representative, variant-labeled Nahuatl text. We describe LID experiments for a total of 11 Nahuatl varieties, achieving generally good results (90.59% ±0.09% in 5-fold cross-validation experiments). Many of the outstanding errors are the result of confusion between three highly similar Huasteca variants.

The term "low-resource" is used pervasively in NLP but communicates almost nothing precise. We propose RAN (Resource Abundance Notation), a compact, multi-dimensional notation for quantifying a language's NLP resource profile. A RAN score is written as S/M/L_1-B_1/L_2-B_2/..., where S = floor(log10(speakers)), M = floor(log10(monolingual sentences)), and each L_i-B_i pair records a bilingual partner and floor(log10(parallel sentences)). Values derive from canonical sources: Wikidata for speakers, OSCAR 23.01 for monolingual corpora, and (where available) OPUS for parallel corpora. We score 20 typologically diverse languages and correlate each profile against published benchmarks for three tasks: machine translation (MT, via NLLB-200 chrF++), named entity recognition (NER, via XTREME XLM-R WikiANN F1), and part-of-speech tagging (POS, via XTREME XLM-R UD accuracy). The RAN components carry complementary information: a linear model using all three explains 52% of MT variance, 76% of NER variance, and 72% of POS variance. Among single predictors, B_max (the largest bilingual corpus, regardless of partner) is strongest for the cross-lingual transfer tasks (NER, POS), while M and B_en are strongest for MT. RAN is designed first as a communication tool, not a predictive model.

For Mapudungun arn→es translation, morphology-aware tokenization can substitute for a 5× increase in model parameters. We fine-tune three sizes of Meta's NLLB-200 on Mapudungun–Spanish translation across eight tokenization strategies, including our novel Morfessor-VC method, which
constrains Morfessor morpheme segmentation to tokens already present in NLLB's pretrained
vocabulary. Our 600M Morfessor-VC model is competitive with our own fine-tuned 3.3B Standard BPE model on arn→es (43.2 vs. 42.9 chrF++, ∆ = +0.3, p = 0.039, 95% CI [0.02, 0.60]) while using five times fewer parameters, and all fine-tuned conditions surpass frontier LLMs by over 27 chrF++. Mapudungun is an indigenous polysynthetic language spoken by 200,000+ Mapuche people in Chile and Argentina, absent from NLLB-200 and not supported by major commercial MT providers; prior work predates large-scale multilingual models and does not address the tokenization challenges posed by its agglutinative
morphology. These results establish new state-of-the-art baselines for Mapudungun MT and provide a practical foundation for community language tools in pedagogy, social media, and language revitalization.

Qom, a language of the Guaycuruan family, is a low-resource language for NLP and speech processing. We present the first parallel Qom–Spanish corpus in a computationally usable format, comprising 33,392 parallel segments, totaling 1,469,905 Qom tokens and 891,344 Spanish tokens. A subset of 2,943 segments excludes Bible-derived content. It includes alignments at different levels: sentences, sentence fragments, and paragraphs, and is compiled from multiple sources, both previously available and newly collected. 
We also present bidirectional neural machine translation baselines based on NLLB-200, achieving competitive performance in both translation directions on the full dataset, and lower performance on the non-Bible subset. An ablation study shows that training exclusively on biblical data reduces performance on non-biblical text, highlighting the importance of domain diversity in low-resource machine translation.

Publicly available spoken language identification (LID) systems provide sparse and inconsistent coverage of indigenous languages of the Americas and languages of the Pacific Islands. No system on HuggingFace covers Central Alaskan Yup'ik except the largest variant of Meta's MMS-LID family, and only three MMS-LID variants cover Samoan, while Whisper and VoxLingua107-based models lack both despite including other Polynesian languages. We describe an ongoing effort to build a coarse-labeled LID dataset for Yup'ik and Samoan from US public broadcast archives, benchmark publicly available LID systems on it, and train a simple MLP classifier on frozen wav2vec~2.0 representations as a prototype. We report preliminary corpus statistics, off-the-shelf model performance, and prototype results. Guided by the distinctive phonological typology of the target languages, we outline a phonologically-informed fine-tuning direction as future work.

This system description presents a Wixarika image captioning system for the AmericasNLP 2026 Shared Task on Cultural Image Captioning for Indigenous Languages. The system uses Spanish as a pivot language, combining CLIP-based image retrieval, Qwen3-VL Spanish caption generation, the official Sheffield-compatible Spanish-to-Wixarika MT model, and character n-gram language-model reranking. We report local 5-fold development results, official test results, error analysis, and implementation details for reproducibility.

Culturally grounded image captioning for under-resourced Indigenous languages is challenging due to severe data scarcity and the need to describe culturally specific visual content. This paper describes our submission to the AmericasNLP 2026 shared task, where we evaluate two architectural paradigms for caption generation across Bribri, Guaraní, Yucatec Maya, Wixárika, and Orizaba Nahuatl. First, we implement a cascaded system that combines a large vision-language model with a machine translation pipeline, showing that culturally contextualized, persona-based prompting improves over the official baseline in most comparable settings. Second, we develop a direct, end-to-end Single-stage approach by adapting PaliGemma 2 using LoRA fine-tuning, continued pre-training, and multilingual joint training. Our single-stage experiments show that, despite severe domain mismatch and reliance on synthetic training data, multilingual training and continued pre-training improve automatic chrF++ relative to single-language LoRA fine-tuning in some settings. Overall, cascaded pipelines remain the strongest among the evaluated approaches under current data constraints, while single-stage models remain a promising but currently data-limited path toward direct Indigenous-language image captioning.

We describe the USP system for the AmericasNLP 2026 Shared Task on Culturally Relevant Image Captioning for Indigenous Languages, covering Guaraní (grn), Maya Yucateco (yua), Nahuatl (nah), Wixárika (hch), and Bribri (bzd). We propose a two-stage cascade: Qwen3-VL-8B-Instruct (Bai et al., 2025) generates Spanish captions via language-specific cultural prompts; language-specific fine-tuned NLLB-200-distilled-600M (NLLB Team et al., 2022) models then translate them into each target language. We train on AmericasNLP 2023 data (Ebrahimi et al., 2023) augmented with public parallel corpora. Our system achieves competitive results, including 3rd place in Guaraní human evaluation (2.41/5.0) and 5th in Bribri (1.09/5.0) among 8 teams. We also report that NLLB-200-distilled-600M silently lacks vocabulary entries for Bribri and Maya Yucateco, producing English output without error.

Multilingual large language models (LLMs) are increasingly used to interpret mental health narratives in settings such as support chatbots, screening, and content moderation. A basic reliability question remains underexplored: when the same narrative is presented in different languages, does a model apply comparable evaluative standards? We study cross-linguistic variation in mental health evaluation between English and Chinese using two widely deployed LLMs (GPT-4o and Qwen3-32B). We separate (i) construct-level evaluative orientation from (ii) decision-level behavior on downstream tasks. At the construct level, we adapt validated psychometric stigma instruments spanning social, self, and health-professional stigma and quantify language-conditioned shifts in model responses. At the decision level, we evaluate models on binary stigma detection and four-way depression severity classification using semantically aligned English--Chinese datasets. Across instruments and models, Chinese prompts elicit systematically higher stigma scores than English prompts. These differences propagate to downstream decisions: Chinese prompts reduce sensitivity in stigma detection and induce a downward shift in predicted depression severity, producing substantially more under-estimation errors. Our findings show that prompt language can shift both evaluative orientation and effective decision thresholds, underscoring the need for multilingual evaluation and calibration before deploying LLMs in socially sensitive domains.

Language Shapes Mental Health Evaluations in Large Language Models

The evaluation of societal biases in NLP models is critically hindered by a geo-cultural gap. This leaves regions such as Latin America severely underserved, making it impossible to adequately assess or mitigate the perpetuation of harmful regional stereotypes in language technologies.

This paper presents LACES, a stereotype association dataset, for 15 Latin American countries. This dataset includes 4,789 stereotype associations\footnote{The de-identified dataset can be accessed via \href{https://github.com/fvialibre/LACES}{GitHub}}, manually created and annotated by 83 participants. The dataset was developed through targeted community partnerships across Latin America.

Additionally, in this paper, we propose a novel adaptive data collection methodology that uniquely integrates the sourcing of new stereotype entries and the validation of existing data within a single, unified workflow. This approach results in a resource with more unique stereotypes than previous static collection methods, enabling a more efficient stereotype collection. The paper further supports the quality of LACES by demonstrating reduced efficacy of debiasing methods on this dataset in comparison to existing popular stereotype benchmarks.
