V.Yu.Semenov Analyzing of time domain distribution of the immittance spectral frequencies and method for their computation |
Acoustic bulletin, Vol. 12 ¹ 4, (2009) |
| The paper deals with considering of the problem of calculation of the immittance spectral frequencies (ISF) being the alternative representation of parameters of the vocal tract. Properties of the inter-frame ISF relative position have been studied. On this base, the novel efficient method for ISF computation has been proposed. The computational characteristics of this method have been compared with those of the standard AMR-WB speech codec. Performance of the method has been analyzed for conditions of voice data loss in the communication channel. |
