Abstract

보코더의 톤검출회로 및 방법에 관한 것으로, 특히 입력신호로 부터 모델 파라메타를 추출하여 톤신호를 검출하는 톤검출회로 및 방법에 관한 것이다.The present invention relates to a tone detection circuit and a method of a vocoder, and more particularly, to a tone detection circuit and a method for detecting a tone signal by extracting model parameters from an input signal.

음성분석시 처리되어 입력된 각종 파라메터를 분석하여 DTMF 및 호진행톤 신호 또는 음성데이타를 검출하여 출력하고 상기 검출된 DTMF 신호를 분석하여 다이얼 키 신호의 종류를 판별하며, 상기 검출된 호진행 톤을 분석하여 링백톤, 다이얼톤, 비지톤임을 판별함으로써, 음성데이타를 신속하게 처리한다.Analyzes various parameters processed and input during voice analysis to detect and output DTMF and call progress signal or voice data, and analyzes the detected DTMF signal to determine the type of dial key signal, and detects the detected call progress tone. By analyzing the ringback tone, dial tone and busy tone, voice data is processed quickly.
