Adaptive Oscillatory Inductive Bias for Modeling Sharp Prosodic Dynamics in Diffusion-Based TTS
Sandipan Dhar, Nirmesh J. Shah, Ashishkumar P. Gudmalwar +1
Diffusion-based text-to-speech (TTS) models have achieved significant improvements in speech quality. However, modeling sharp prosodic transitions and rapid pitch variations in exp…
CrossAccent-TTS: Cross-Lingual Accent-Intensity Controllable Text-to-Speech via Disentangled Speaker and Accent Representations
Ram Annamdevula, Ankit Tatawat, Ashishkumar P. Gudmalwar +2
Accent conversion and controllability remain fundamental challenges in cross-lingual text-to-speech (TTS), particularly for low-resource and phonetically diverse Indic languages. W…
Overcoming Decoder Inconsistencies in Whisper for Dravidian and Low-Resource Languages
Chowdam Venkata Kumar, Kumud Tripathi, Pankaj Wasnik
Multilingual ASR models such as Whisper perform well on high-resource languages but exhibit substantially higher Word Error Rates (WER) for Dravidian languages compared to Indo-Ary…
Graph-Based Phonetic Error Correction of Noisy ASR
Pratik Rakesh Singh, Mohammadi Zaki, Aneesh Mukkamala +1
Automatic speech recognition (ASR) systems, despite low overall word error rates, produce residual lexical errors that disproportionately affect semantically critical tokens such a…
