1.	________ is often called the formant of the speech signal.(a) Pitch frequency(b) Voice pitch(c) Pole frequency(d) Central frequencyThis question was posed to me during an interview for a job.This interesting question is from Vocoders in section Speech Coding of Wireless/Mobile
Answer» Correct ANSWER is (c) Pole frequency The EXPLANATION is: The pole frequencies correspond to the resonant frequencies of the vocal TRACT. They are often CALLED the formants of the speech signal. For ADULT speakers, the formants are centered around 500 Hz, 1500 Hz, 2500 Hz and 3500 Hz.
