چکیده

This paper presents an approach to parametric voice conversion that can be used in real-time entertainment applications. The approach is based on spectral mapping using an artificial neural network (ANN) with rectified linear units (ReLU). To overcome the oversmoothing problem a special network configuration is proposed that utilizes temporal states of the speaker. The speech is represented using the harmonic plus noise model. The parameters of the model are estimated using instantaneous harmonic parameters. Using objective and subjective measures the proposed voice conversion technique is compared to the main alternative approaches.

Real-time and non-real-time voice conversion systems with web interfaces

Two speech processing systems have been developed for realtime and non-real-time voice conversion. Using the real-time processing the user can apply conversion during voice over IP (VoIP) calls imitating identity of a specified target speaker. Non-real-time processing system converts prerecorded audio books read by a professional reader imitating voice of the user. Both systems require some spe...

Flexible Rectified Linear Units for Improving Convolutional Neural Networks

Rectified linear unit (ReLU) is a widely used activation function for deep convolutional neural networks. In this paper, we propose a novel activation function called flexible rectified linear unit (FReLU). FReLU improves the flexibility of ReLU by a learnable rectified point. FReLU achieves a faster convergence and higher performance. Furthermore, FReLU does not rely on strict assumptions by s...

DReLUs: Dual Rectified Linear Units

Rectified Linear Units (ReLUs) are widely used in feed-forward neural networks, and in convolutional neural networks in particular. However, they can be rarely found in recurrent neural networks due to the unboundedness and the positive image of the rectified linear activation function. In this paper, we introduce Dual Rectified Linear Units (DReLUs), a novel type of rectified unit that comes w...
