TukaBench: A Culturally Grounded Jailbreak Benchmark for African Languages

Researchers introduce TukaBench, a jailbreak safety benchmark for seven African languages that reveals LLMs are significantly more vulnerable to adversarial prompts when queried in African languages versus English, with culturally adapted prompts proving most effective at bypassing safety measures. The study identifies critical gaps in LLM safety evaluation for low-resource languages and demonstrates that existing judging mechanisms fail to accurately assess model responses in these languages.

WAXAL: A Large-Scale Multilingual African Language Speech Corpus

Researchers have released WAXAL, a large-scale multilingual speech dataset covering 24 Sub-Saharan African languages representing over 100 million speakers. The dataset includes 1,250 hours of transcribed speech for ASR and 235 hours of high-quality recordings for TTS, released under CC-BY-4.0 license to advance inclusive AI technologies.

Evaluating Large Language Models for Hausa and Fongbe Machine Translation: Benchmarks, Failures, and Metric Reliability

Researchers evaluated four major LLMs (GPT-4o Mini, Claude Sonnet 4, Gemini 2.5 Flash, Qwen2.5-7B) on English-to-Hausa and English-to-Fongbe translation, finding that translation quality varies dramatically by language, model rankings differ across languages, and automatic evaluation metrics show weak correlation with human judgment for low-resource African languages.

From Speech to Text Corpora: Evaluating ASR-Based Data Acquisition for Low-Resource Fongbe and Hausa

Researchers successfully fine-tuned automatic speech recognition (ASR) models to create text corpora for low-resource African languages Fongbe and Hausa, achieving significant improvements in transcription accuracy. The work demonstrates ASR's potential for rapidly expanding language resources in underrepresented languages, though quality varies by linguistic complexity, with Hausa transcriptions approaching production-ready standards while Fongbe requires further refinement.

ANGOFA: Leveraging OFA Embedding Initialization and Synthetic Data for Angolan Language Model

Researchers introduced ANGOFA, four pre-trained language models tailored for Angolan languages using Multilingual Adaptive Fine-tuning (MAFT) with OFA embedding initialization and synthetic data. The approach achieved 12.3 and 3.8 point improvements over previous state-of-the-art models, addressing a critical gap in NLP support for very-low resource African languages.

Paza: Introducing automatic speech recognition benchmarks and models for low resource languages

Microsoft Research launched Paza, a human-centered speech recognition pipeline, and PazaBench, the first benchmark leaderboard specifically designed for low-resource languages. The initiative covers 39 African languages with 52 models and has been tested with real communities to improve AI accessibility for underrepresented languages.
