High-Resolution Speech Restoration with Latent Diffusion Model

1 code implementation17 Sep 2024 Tushar Dhyani, Florian Lux, Michele Mancusi, Giorgio Fabbro, Fritz Hohl, Ngoc Thang Vu

Traditional speech enhancement methods often oversimplify the task of restoration by focusing on a single type of distortion.

Probing the Feasibility of Multilingual Speaker Anonymization

1 code implementation3 Jul 2024 Sarina Meyer, Florian Lux, Ngoc Thang Vu

In speaker anonymization, speech recordings are modified in a way that the identity of the speaker remains hidden.

Meta Learning Text-to-Speech Synthesis in over 7000 Languages

1 code implementation10 Jun 2024 Florian Lux, Sarina Meyer, Lyonel Behringer, Frank Zalkow, Phat Do, Matt Coler, Emanuël A. P. Habets, Ngoc Thang Vu

In this work, we take on the challenging task of building a single text-to-speech synthesis system that is capable of generating speech in over 7000 languages, many of which lack sufficient data for traditional TTS development.

Controlling Emotion in Text-to-Speech with Natural Language Prompts

1 code implementation10 Jun 2024 Thomas Bott, Florian Lux, Ngoc Thang Vu

In recent years, prompting has quickly become one of the standard ways of steering the outputs of generative machine learning models, due to its intuitive use of natural language.

Controllable Generation of Artificial Speaker Embeddings through Discovery of Principal Directions

no code implementations26 Oct 2023 Florian Lux, Pascal Tilli, Sarina Meyer, Ngoc Thang Vu

Customizing voice and speaking style in a speech synthesis system with intuitive and fine-grained controls is challenging, given that little data with appropriate labels is available.

The IMS Toucan System for the Blizzard Challenge 2023

1 code implementation26 Oct 2023 Florian Lux, Julia Koch, Sarina Meyer, Thomas Bott, Nadja Schauffler, Pavel Denisov, Antje Schweitzer, Ngoc Thang Vu

For our contribution to the Blizzard Challenge 2023, we improved on the system we submitted to the Blizzard Challenge 2021.

Low-Resource Multilingual and Zero-Shot Multispeaker TTS

1 code implementation21 Oct 2022 Florian Lux, Julia Koch, Ngoc Thang Vu

While neural methods for text-to-speech (TTS) have shown great advances in modeling multiple speakers, even in zero-shot settings, the amount of data needed for those approaches is generally not feasible for the vast majority of the world's over 6, 000 spoken languages.

Anonymizing Speech with Generative Adversarial Networks to Preserve Speaker Privacy

1 code implementation13 Oct 2022 Sarina Meyer, Pascal Tilli, Pavel Denisov, Florian Lux, Julia Koch, Ngoc Thang Vu

In order to protect the privacy of speech data, speaker anonymization aims for hiding the identity of a speaker by changing the voice in speech recordings.

Speaker Anonymization with Phonetic Intermediate Representations

1 code implementation11 Jul 2022 Sarina Meyer, Florian Lux, Pavel Denisov, Julia Koch, Pascal Tilli, Ngoc Thang Vu

In this work, we propose a speaker anonymization pipeline that leverages high quality automatic speech recognition and synthesis systems to generate speech conditioned on phonetic transcriptions and anonymized speaker embeddings.

Exact Prosody Cloning in Zero-Shot Multispeaker Text-to-Speech

2 code implementations24 Jun 2022 Florian Lux, Julia Koch, Ngoc Thang Vu

The cloning of a speaker's voice using an untranscribed reference sample is one of the great advances of modern neural text-to-speech (TTS) methods.

Language-Agnostic Meta-Learning for Low-Resource Text-to-Speech with Articulatory Features

1 code implementation ACL 2022 Florian Lux, Ngoc Thang Vu

While neural text-to-speech systems perform remarkably well in high-resource scenarios, they cannot be applied to the majority of the over 6, 000 spoken languages in the world due to a lack of appropriate training data.

Meta-Learning for improving rare word recognition in end-to-end ASR

no code implementations25 Feb 2021 Florian Lux, Ngoc Thang Vu

We propose a new method of generating meaningful embeddings for speech, changes to four commonly used meta learning approaches to enable them to perform keyword spotting in continuous signals and an approach of combining their outcomes into an end-to-end automatic speech recognition system to improve rare word recognition.

ADVISER: A Toolkit for Developing Multi-modal, Multi-domain and Socially-engaged Conversational Agents

1 code implementation ACL 2020 Chia-Yu Li, Daniel Ortega, Dirk Väth, Florian Lux, Lindsey Vanderlyn, Maximilian Schmidt, Michael Neumann, Moritz Völkel, Pavel Denisov, Sabrina Jenne, Zorica Kacarevic, Ngoc Thang Vu

We present ADVISER - an open-source, multi-domain dialog system toolkit that enables the development of multi-modal (incorporating speech, text and vision), socially-engaged (e. g. emotion recognition, engagement level prediction and backchanneling) conversational agents.

Multiclass Text Classification on Unbalanced, Sparse and Noisy Data

no code implementations WS 2019 Matthias Damaschk, Tillmann D{\"o}nicke, Florian Lux

This paper discusses methods to improve the performance of text classification on data that is difficult to classify due to a large number of unbalanced classes with noisy examples.
