In modern world, communication service providers are continuously met with the challenge of accommodating more users with in a limited allocated bandwidth. Due to this motivation service providers and manufactures are continuously in search of low bit rate speech coders that deliver high quality speech. The main objective of speech compression is to reduce the bits rate of speech for communication or storage without significant loss of its intelligibility. Wavelet based speech coding is a new technique used for speech compression. The main issue regarding wavelet based speech coding is to choose optimal wavelet to transform the speech signal. In this experiment we use two types of wavelets orthogonal and bi-orthogonal wavelets to transform the speech signal. Run length encoding algorithm is used to encode the threshold coefficient. Performance of this experiment is evaluated in terms of MSE, SNR, PSNR, RSE, and in terms of compression percentage
