Quizplus · Accepted Answer

A spectrograph is a type of electronic machine that can analyze the frequency and intensity of sound waves, making it useful in comparing a suspect's voice to a recorded voice. Microphones are used to record sound, but they do not have the capability to analyze the frequency and intensity of sound waves in the same way as a spectrograph. A voice exemplar is a sample of a person's voice used for comparison purposes, and a phraseometer is not a real word that is used in the field of voice analysis.
