Abstract
A method and associated system and computer program product. A sample of speech, for which a source of the sample of speech is to be classified, is received. A frequency clip level of the sample of speech is determined. A higher frequency clip level indicates the source is human and a lower frequency clip level indicates the source is machine generated. A dynamic range of the sample of speech is determined. A lower dynamic range indicates the source is human and a higher dynamic range indicates the source is machine generated. The frequency clip level and the dynamic range are weighted by a respective weighting factor as to whether the source is human or the source is machine generated. The source is classified as human generated or machine generated. The classifying of the source is based on the frequency clip level, the dynamic range, and the respective weighting factors thereof.
