Claim:
1. A method comprising: obtaining, by a computing device via a speech analyzer, a waveform representing a digital recording of audio speech of a person, the speech analyzer comprising at least one of a microphone, an interface to a sound recorder, an interface to a database, or an interface to a data storage system; measuring, by the computing device, amplitudes of waves within the waveform, the waves corresponding to samples of the digital recording of the audio speech of the person; classifying, by a silence detector of the computing device, the samples of the digital recording of the audio data of the speech of the person, based on the measured amplitudes of the samples and on a silence threshold, into a first class of samples including speech or sound and a second class of samples including silence, wherein classifying the samples comprises: analyzing, by the computing device, the first class of samples to determine a number of words spoken by the person; calculating, by the computing device, a verbal fluency score for the person based at least in part on the determined number of words spoken by the person, and outputting, by the computing device, the verbal fluency score.
