it provided significantly better quality than existing low bit-rate algorithms, such as RELP and LPC vocoders Introduction The CELP algorithm is based on four main ideas: • Using the source-filter model of speech production through linear prediction (LP)(see the textbook "speech coding algorithm"); • Using an adaptive and a fixed codebook as the input (excitation) of the LP model; • Performing a search in closed-loop in a “perceptually weighted domain”. • Applying vector quantization (VQ) • Before exploring the complex encoding process of CELP we introduce the decoder here. Figure 1 describes a generic CELP decoder. The excitation is produced by summing the contributions from an adaptive (aka pitch) codebook and a fixed (aka innovation or stochastic) codebook: • • where ea[n] is the adaptive (pitch) codebook contribution and ef[n] is the fixed (innovation) codebook contribution. The fixed codebook is a vector quantization dictionary that is (implicitly or explic

USAGE OF TD PSOLA ALGORITHM IN SLOVAK SPEECH SYNTHESIS BASED ON THE EMU DATABASE SYSTEM Andrej VRÁBEL, Bachelor Degree Programme (4) Dept. of Telecommunications, FEI STU Bratislava E-mail: av2@post. sk Supervised by: Dr. Gregor Rozinaj ABSTRACT Speech synthesis is the process of generating acoustical signal, represented by a sequence of vowels, with particular factual and grammatical meaning. One of the possibilities for speech synthesis is concatenate synthesis, in which prepared partitions of human speech are concatenated, by using convenient algorithms. The use of the EMU database system, in phoneme based speech synthesis has been reviewed. This paper continues research of this area. At the beginning, it analyses the TD PSOLA algorithm. Then, it solves the problem of adaptation the EMU system for diphone based text-to-speech synthesis. Finally, it introduces the possibility of implementation the algorithm in the EMU system. 1 INTRODUCTION The TD PSOLA (Time-Domain Pitch Syn
