Researchers introduce SAMPA, a Whisper large-v3 fine-tuned model for automatic prosodic boundary segmentation in Brazilian Portuguese speech. The model is trained on the NURC-SP dataset and achieves F1=0.731 on held-out test data and F1=0.796 on the out-of-distribution MuPe-Diversidades dataset. The work addresses a gap in NLP tooling for Brazilian Portuguese, where prior approaches relied on rule-based or traditional ML methods rather than modern deep learning.
A new arXiv preprint compares human listeners against three off-the-shelf ASR systems (Whisper-large-V3, Google Chirp 3, and Omnilingual) on recognizing continuous Dutch speech from a single speaker with severe dysarthria. Both humans and ASR systems exceeded 70% WER on average, confirming the extreme difficulty of dysarthric speech recognition. Fine-tuning on dysarthric speech substantially reduced WER, with personalized models outperforming human listeners, though WER remained above 23%. The study highlights the need for personalized ASR approaches for dysarthric speakers.
OpenAI is shutting down its Sora text-to-video platform without explanation, ending a major Disney licensing deal worth up to $1 billion and eliminating video capabilities from ChatGPT amid Hollywood copyright tensions. Anthropic published details on a multi-agent harness enabling Claude to build full-stack applications over multi-hour sessions using a planner-generator-evaluator architecture. ServiceNow AI Research released EVA, an open-source two-dimensional benchmark for voice agents measuring both task accuracy and conversational experience quality. Additional items cover Arm's first self-designed data center CPU (AGI CPU) co-developed with Meta, and the Trump Administration's legislative proposal for a federal AI framework that would preempt state AI laws.
Mistral AI has released Voxtral, a family of two open-weight speech understanding models (Voxtral Small at 24B and Voxtral Mini at 3B) under the Apache 2.0 license. Both models support long-form audio up to 30-40 minutes, native multilingual transcription, built-in Q&A and summarization, and function-calling directly from voice, built on the Mistral Small 3.1 language model backbone. Benchmarks show Voxtral outperforms Whisper large-v3 across all tasks and is competitive with GPT-4o mini and Gemini 2.5 Flash on audio understanding, while pricing starts at $0.001/minute via API. Models are available on Hugging Face and through Mistral's API, with a transcription-optimized variant (Voxtral Mini Transcribe) also offered.
