ABSTRAKT

In speech analysis, voiced/unvoiced decision is usually performed in extracting the information from the speech signals. This paper presented a new approach for voiced/unvoiced (V/UV) decision; the approach is used Lagrange polynomial interpolation for voiced/ unvoiced signals speech decision, depending on the advantage of the characteristics of the interpolation techniques. Speech file is divided in different size of blocks, each block is evaluated by Lagrange technique, and the results are evaluated by one of most popular voiced/unvoiced measured which is the short time energy classifier. The results show that Lagrange technique worked well as classifier and give an accepted decision to analysis the speech to voice and unvoiced sample, especially with small size non overlapping blocks.
