The paper presents a voice conversion technique that can be used in real-time applications. The technique is based on transformation of short-time spectral envelopes of speech using artificial neural network with Rectified Linear Units. A special network configuration is used that takes into account temporary speaker states. Speech is represented as instantaneous parameters of the harmonic + noise model. The proposed voice conversion technique is compared to main alternative techniques using objective and subjective measures.
