Abstract

The present invention is directed inter alia to a method and a speech-based system (120) for automatically detecting synthesized or natural speech. The system (120) comprises a computational system (180) including a memory (181), which may store a trained classification algorithm, a communication interface (183) configured to receive speech signals addressed to the at least one communication apparatus, a data processing unit (182) configured toi) divide up the speech signals received at the communication interface (183) into portions, each portion having a predetermined duration,ii) to evaluate an index value by executing the classification algorithm stored in the memory (181) on at least one of the portions, andiii) to determine in dependence of the first and second predefined index value and in dependence of the index value evaluated, whether the at least one portion belongs to a synthesized speech signal or to a natural speech signal.
