AB  - A method for encoding wideband speech signal employing standardized narrowband speech codecs is presented as well as experimental results concerning detection of tonal spectral components. The speech signal sampled with a higher sampling rate than it is suitable for narrowband coding algorithm is compressed in order to decrease the amount of samples. Next, the time-compressed representation of a signal is encoded using a narrowband speech codec. The time expansion procedure is applied to the speech signal after transmission and decoding in order to restore original time relations. Finally, the wideband speech signal is presented to the user. The method for spectral envelope estimation involving perceptual criteria is described. The algorithms for tonal components detection were evaluated and compared during experiments carried-out.
