US Patent No: 5991611

Volume control device for receiver of block coded speech signals

---

Abstract

---

A receiver of block coded speech signals receives signals transmitted by means of discontinuous transmission and estimates the acceptable or unacceptable nature of the blocks received. A volume control device commands reduction of the volume in the case of reception of unacceptable blocks. A detector, on the basis of the results of the estimate, determines if the signals received are signals transmitted using discontinuous transmission. The volume is restored in the case of such detection.
