Deep Learning Based Vietnamese Diacritics Restoration

2019

Diacritics are very important in diacritical languages, because the meaning of sentences can be changed in accordance to diacritics. Writing without diacritics makes the sentences ambiguous; however, there are several reasons make people do not …

Evaluation of Attention Mechanisms on Text to Speech

2021

Attention mechanisms have been widely used in sequence to sequence tasks. Among those tasks, attention-based neural text to speech synthesis with monotonic property has shown a powerful ability to generate natural speech. This paper introduces …

A Comparative Study of Cross-Model Universal Adversarial Perturbation for Face Forgery

2022 · 2022 IEEE International Conference on Visual Communications and Image Processing (VCIP)

Although the rapid development of deep generative models (DGM) enables diverse applications of content creation, increasing illegal uses of the technologies also severely threaten the privacy and security of personal information, especially for faces. Several …

Low-Resource Speech Recognition Based on Transfer Learning

2022 · 2022 RIVF International Conference on Computing and Communication Technologies (RIVF)

A lot of research aims to improve accuracy in end-to-end speech recognition, and achieves higher accuracy on various famous corpora. However, there are many languages which do not have enough data to build their speech …

Zero-Shot Voice Conversion Based on Speaker Embedding Domain Generalization

2023

In this paper, a zero-shot voice conversion frame-work is constructed by effectively decoupling the semantic and speaker features in speech. The proposed method is based on the pre-trained wav2vec 2.0 model to extract semantic features …
