To ensure high enough recognition performance from the outset of usage of the speech recognition system, prior development of highly precise acoustic model library is necessary. The analysis of HMM acoustic models expressed with Gaussian distributions of multidimensional vectors is typically a difficult task. The COSMOS (aCOustic Space Map Of Sound) method featuring the visualization of distributions of the acoustic models in a two dimensional space by utilizing multidimensional scaling… CONTINUE READING
