As such it is the interface 35 * between text analysis and signal generation 36 * 37 * Most the processing of PAM is logically splittable as follows 38 * - building a suitable symbolic feature vector set for the sentence 39 * - Feeding Decision Trees with the symbolic seqence vector set 40 * - Colecting the parametric output of the Decision trees into suitable items to be sent to following PU's 41 * 42 * To perform the decision tree feeding and output collection the PU uses an internal buffer. This 43 * buffer is used several times with different meanings. 44 * - While building the symbolic feature vector set for the sentence this data structure stores syllable relevant data. 45 * The corresponding phonetic data is stored outside as a single string of phonetic id's for all the sentence. 46 * - While feeding the decision trees the data structure is used to represent data for phonemes of the syllable 47 * - Addiotional data strucures are mantained to temporarily store items not pertaining to the PAM processing, for later resynchronization 48 * 49 * A quite detailed description of PAM processing is in the Know How section of the repository. 50 */ 51 52 #ifndef PICOPAM_H_ 53 #define PICOPAM_H_ 54 55 #include "picodata.h" 56 #include "picokdt.h" 57 #include "picokpdf.h" 58 #include "picoktab.h" 59 #include "picokdbg.h" 60 61 #ifdef __cplusplus 62 extern "C" { 63 #endif 64 #if 0 65 } 66 #endif 67 68 /*------------------------------------------------------------------ 69 Service routines 70 ------------------------------------------------------------------*/ 71 picodata_ProcessingUnit picopam_newPamUnit( 72 picoos_MemoryManager mm, picoos_Common common, 73 picodata_CharBuffer cbIn, picodata_CharBuffer cbOut, 74 picorsrc_Voice voice); 75 76 #ifdef __cplusplus 77 } 78 #endif 79 #endif /*PICOPAM_H_*/ 80
