Conference Object Developing an Automatic Transcription and Retrieval System for Spoken Lectures in Turkish(Institute of Electrical and Electronics Engineers Inc., 2017) Arisoy, EbruConference Object Citation - WoS: 1Evaluating Large Language Models in Data Generation for Low-Resource Scenarios: A Case Study on Question Answering(International Speech Communication Association, 2025) Arisoy, Ebru; Menevse, Merve Unlu; Manav, Yusufcan; Ozgur, ArzucanLarge Language Models (LLMs) are powerful tools for generating synthetic data, offering a promising solution to data scarcity in low-resource scenarios. This study evaluates the effectiveness of LLMs in generating question-answer pairs to enhance the performance of question answering (QA) models trained with limited annotated data. While synthetic data generation has been widely explored for text-based QA, its impact on spoken QA remains underexplored. We specifically investigate the role of LLM-generated data in improving spoken QA models, showing performance gains across both text-based and spoken QA tasks. Experimental results on subsets of the SQuAD, Spoken SQuAD, and a Turkish spoken QA dataset demonstrate significant relative F1 score improvements of 7.8%, 7.0%, and 2.7%, respectively, over models trained solely on restricted human-annotated data. Furthermore, our findings highlight the robustness of LLM-generated data in spoken QA settings, even in the presence of noise.Conference Object A Framework for Automatic Generation of Spoken Question-Answering Data(Association for Computational Linguistics (ACL), 2022) Özgür, Arzucan; Menevşe, Merve Ünlü; Arisoy, Ebru; Manav, YusufcanConference Object Turkish Broadcast News Transcription Revisited(Institute of Electrical and Electronics Engineers Inc., 2018) Arisoy, Ebru; Saraglar, Murat
