Block Encoding Of Speech Spectral Principal Components, James R. Holland Jr.
Block Encoding Of Speech Spectral Principal Components, James R. Holland Jr.
Electrical & Computer Engineering Theses & Dissertations
A Karhunen-Loeve series expansion was used to block encode speech spectral principal components as a function of time. Each of ten principal components was first obtained as a linear combination of 2© speech spectral band energies. Using a fixed block length of 10 frames (0.128 s), the K-L basis vectors were computed separately for various speakers for each principal component. In all cases the resulting basis vectors were essentially a set of discrete cosine basis vectors. Synthesis of speech from the block encoded parameters showed that very little information is lost with up to 70% data reduction. The block encoding …
