Fast and small footprint Hybrid HMM-HiFiGAN based system for speech synthesis in Indian languages

no code implementations13 Feb 2023 Sudhanshu Srivastava, Ishika Gupta, Anusha Prakash, Jom Kuriakose, Hema A. Murthy

Hidden-Markov-model (HMM) based text-to-speech (HTS) offers flexibility in speaking styles along with fast training and synthesis while being computationally less intense.

Speech Synthesis

HMM-based data augmentation for E2E systems for building conversational speech synthesis systems

no code implementations22 Dec 2022 Ishika Gupta, Anusha Prakash, Jom Kuriakose, Hema A. Murthy

This paper proposes an approach to build a high-quality text-to-speech (TTS) system for technical domains using data augmentation.

Front-end Diarization for Percussion Separation in Taniavartanam of Carnatic Music Concerts

no code implementations4 Mar 2021 Nauman Dawalatabad, Jilt Sebastian, Jom Kuriakose, C. Chandra Sekhar, Shrikanth Narayanan, Hema A. Murthy

In this work, we address the problem of separating the percussive voices in the taniavartanam segments of Carnatic music.

Towards Zero-Shot Learning with Fewer Seen Class Examples

no code implementations14 Nov 2020 Vinay Kumar Verma, Ashish Mishra, Anubha Pandey, Hema A. Murthy, Piyush Rai

We present a meta-learning based generative model for zero-shot learning (ZSL) towards a challenging setting when the number of training examples from each \emph{seen} class is very few.

Evidence of Task-Independent Person-Specific Signatures in EEG using Subspace Techniques

no code implementations27 Jul 2020 Mari Ganesh Kumar, Shrikanth Narayanan, Mriganka Sur, Hema A. Murthy

These high dimensional statistics are then projected to a lower dimensional space where the biometric information is preserved.

Stacked Adversarial Network for Zero-Shot Sketch based Image Retrieval

no code implementations18 Jan 2020 Anubha Pandey, Ashish Mishra, Vinay Kumar Verma, Anurag Mittal, Hema A. Murthy

Conventional approaches to Sketch-Based Image Retrieval (SBIR) assume that the data of all the classes are available during training.

Spoof detection using time-delay shallow neural network and feature switching

1 code implementation16 Apr 2019 Mari Ganesh Kumar, Suvidha Rupesh Kumar, Saranya M, B. Bharathi, Hema A. Murthy

When combined with the decision-level feature switching (DLFS) paradigm, the best TD-SNN system outperforms the best baseline GMM system on evaluation data with a relative improvement of 48. 03\% and 49. 47\% for both logical and physical access, respectively.

A Generative Model For Zero Shot Learning Using Conditional Variational Autoencoders

no code implementations3 Sep 2017 Ashish Mishra, M Shiva Krishna Reddy, Anurag Mittal, Hema A. Murthy

By extensive testing on four benchmark datasets, we show that our model outperforms the state of the art, particularly in the more realistic generalized setting, where the training classes can also appear at the test time along with the novel classes.
