In the next generation of mobile systems more efficient speech classification algorithms are required, above all in the presence of background noise. In this context, voicing detection is a crucial point in the perceived quality and naturalness of a very low bit-rate speech coder. The paper presents a neural based approach to robust voiced/unvoiced speech classification in mobile environments. The results show that the performance of the neural classifier proposed in the presence of various types of background noise is better than that of traditional methods.
