The Impact of Side Information on Voice Privacy
Eulalie Thiombiano, Martha Larson, Vincent Colotte +1
Currently, voice-related privacy risks are studied under the assumption that the attacker has access only to spoken audio. In contrast, real-world collections often pair the speech…
An Exhaustive Evaluation of TTS- and VC-based Data Augmentation for ASR
Sewade Ogun, Vincent Colotte, Emmanuel Vincent
Augmenting the training data of automatic speech recognition (ASR) systems with synthetic data generated by text-to-speech (TTS) or voice conversion (VC) has gained popularity in r…
Stochastic Pitch Prediction Improves the Diversity and Naturalness of Speech in Glow-TTS
Sewade Ogun, Vincent Colotte, Emmanuel Vincent
Flow-based generative models are widely used in text-to-speech (TTS) systems to learn the distribution of audio features (e.g., Mel-spectrograms) given the input tokens and to samp…
Can we use Common Voice to train a Multi-Speaker TTS system?
Sewade Ogun, Vincent Colotte, Emmanuel Vincent
Training of multi-speaker text-to-speech (TTS) systems relies on curated datasets based on high-quality recordings or audiobooks. Such datasets often lack speaker diversity and are…
