Abstract:
An apparatus for distinguishing between a voice signal and a non-voice signal prior to transmission comprising:a voice encoding unit for encoding a voice signal and a voice decoding unit for decoding the encoded voice signal transmitted from said voice encoding unit,said voice encoding unit comprising:signal detection means for detecting whether an input signal is a voice signal or a non-voice signal and outputting a signal identification signal on the basis of the detection result; andvoice encoding means for, when said signal detection means detects a voice signal, encoding the input signal as the voice signal and transmitting encoded data to said voice decoding unit,wherein when said signal detection means detects a non-voice signal, said voice encoding unit transmits the input signal directly to said voice decoding unit as non-encoded transmission data thus bypassing said voice encoding means; andsaid voice decoding unit comprising;voice decoding means for, when said signal detection means detects the voice signal, decoding the encoded data transmitted from said voice encoding means and outputting the decoded voice signal, andfirst switching means for selecting, on the basis of the signal identification signal output from said signal detection means, one of the decoded voice signal output from said voice decoding means and the non-encoded transmission data transmitted from said voice encoding unit.
