WaveNet est un modèle informatique largement utilisé dans is a type of modèle d'apprentissage profond développé par DeepMind, primarily designed for generating audio, including speech and music. Unlike traditional models that use simple waveforms for sound synthesis, WaveNet leverages a more complex approach using réseaux neuronaux pour produire directement des formes d'onde audio.
L'architecture est basée sur un réseau de neurones convolutionnels (CNN) that uses a stack of dilated causal convolutions. This allows the model to capture long-range dependencies in audio data, making it capable of generating high-fidelity audio that closely mimics human speech patterns and musical nuances.
One of the key features of WaveNet is its ability to generate audio sample by sample, predicting the next audio sample based on the previous ones. This autoregressive process enables the model to produce smoother and more coherent audio. Additionally, WaveNet can be conditioned on various inputs, such as text or other audio signals, to create contextually relevant audio outputs.
WaveNet has shown impressive results in text-to-speech (TTS) applications, significantly improving the naturalness and expressiveness of synthesized speech. Its architecture can also be adapted for other tasks, such as génération de musique and environmental sound synthesis. As a result, WaveNet has become a foundational model in the field of audio processing and has influenced various subsequent innovations in deep learning for audio.
