A speech signal isolation system configured to isolate and reconstruct a speech signal transmitted in an environment in which frequency components of the speech signal are masked by background noise. The speech signal isolation system obtains a noisy speech signal from an audio source. The noisy speech signal may then be fed through a neural network that has been trained to isolate and reconstruct a clean speech signal from against background noise. Once the noisy speech signal has been fed through the neural network, the speech signal isolation system generates an estimated speech signal with substantially reduced noise.
Un système d'isolation de signaux vocaux est configuré pour isoler et reconstituer un signal vocal transmis dans un environnement dans lequel les composantes en fréquence du signal vocal sont masquées par le bruit de fond. Le système d'isolation de signaux vocaux obtient le signal vocal bruité d'une source audio. Le signal vocal bruité peut alors être injecté dans un réseau neuronal qui a été entraîné pour isoler et reconstruire un signal vocal propre extrait du bruit de fond. Une fois le signal vocal bruité injecté dans le réseau neuronal, le système d'isolation des signaux vocaux génère un signal vocal estimé dont le bruit est sensiblement réduit.
