Type: conference-paper
Abstract: This paper presents our contribution to the IWSLT Low Resource Track 2: "Training and Evaluation Data Track".We share a human-evaluated Urdu-English speech-to-text corpus based on Common Voice 13.0 Urdu speech corpus.We followed a three-tier validation scheme which involves an initial automatic translation with corrections from native reviewers, full review by evaluators followed by final validation from a bilingual expert ensuring reliable corpus for subsequent NLP tasks.Our contribution, CV-UrEnST corpus, enriches Urdu speech resources by contributing the first Urdu-English speech-totext corpus.When evaluated with Whispermedium, the corpus yielded a significant improvement to the vanilla model in terms of BLEU, chrF++, and COMET scores, demonstrating its effectiveness for speech translation tasks.
