Mind the Accent Gap: British Accent Robustness in Speech-Driven Financial Voice Assistants

Read the original on Hugging Face Trending Papers →

The paper highlights that AI voice assistants using ASR and LLMs struggle with regional British accents because most ASR models are trained on American English. It introduces CavaBench, a benchmark of spoken financial queries, to evaluate ASR models and their impact on downstream tool‑calling accuracy across British accents. The study finds that while WER predicts tool‑calling accuracy, it may not fully capture task‑level performance, revealing accent‑related failures that vary by model and acoustic conditions.

Earnings25: A Comprehensive 500-Hour Speech Benchmark for Finance

We introduce Earnings25, a finance-domain benchmark for evaluating automatic speech recognition (ASR) on English-language earnings calls under realistic conditions. Earnings25 comprises two complementary test sets: (i) testset-full, 498 hours of full English-language S&P 500 earnings calls from Q4 2025, and (ii) testset-segmented, a 46-hour industry-balanced set of 290 segments sampled from English-language U.

VoiceLongMemEval: Do Assistants Remember How You Sounded?

VoiceLongMemEval (VLME) is a new benchmark that tests AI assistants on their ability to remember how users sounded by incorporating paralinguistic metadata—such as emotion labels, prosody descriptors, and voice events—into each conversational turn. The benchmark uses a three‑stage adversarial gate to ensure that models cannot succeed with transcript alone, revealing a significant affect gap: models gain 0.09 to 0.38 accuracy when provided with paralinguistic cues, and audio‑native models outperform standard ASR pipelines in extracting these signals. The dataset and code will be released upon acceptance.

RW-Voice-EQ Bench: A Real World Benchmark for Evaluating Voice AI Systems

arXiv:2607. 14846v1 Announce Type: cross Abstract: Current voice AI benchmarks typically evaluate isolated capabilities such as speech intelligibility, word error rate, or text-based dialogue quality, but they rarely test whether systems harness the acoustic information that distinguishes spoken language from its textual representation.
