Using a Waveform Dictionary
نویسنده
چکیده
A new method for speech synthesis by concatenating waueforms selected from a dictionary is described. An adult male recorded a two-hour speech with acoustic phonetic labels. This data was used to construct the dictionary. The dictionary contains 35,000 waueforms which are identified by their duration, auerage pitch, pitch contour and auerage energy. The number of the phonetic labels is thirtyfiue. In the speech synthesis phase, giuen a phoneme string and prosody information, the optimum waueforms are selected by matehing their attributes with the giuen phonetic and prosodic information. The matehing score is defined as a function of phonetic coincidence and prosodic attribute differences. Selected waueforms are then concatenated to produce speech. The speech has high intelligibility and naturalness.

A v-CV waveform based speech synthesis using global minimization of pitch conversion and concatenation distortion in v-CV unit sequence
This paper proposes a new speech synthesis method for high-quality Japanese TTS(Text-to-speech) based on the waveform synthesis. The method uses V-CV as a basic synthesis unit to preserve the intelligibility of consonant. An efficient unit reconstruction method is newly adopted both to minimize pitch conversion and concatenation distortion when selecting waveforms. The minimization can provide ...
متن کاملOptimized signal expansions for sparse representation
Traditional signal decompositions such as transforms, filterbanks, and wavelets generate signal expansions using the analysis–synthesis setting: The expansion coefficients are found by taking the inner product of the signal with the corresponding analysis vector. In this paper, we try to free ourselves from the analysis–synthesis paradigm by concentrating on the synthesis or reconstruction part...

This paper uses waveform dictionaries to decompose the signals contained within three foreign exchange rates using tick-by-tick observations obtained world wide. The three exchange rates examined are the Japanese Yen and the German Deutsche Mark against the U.S. dollar and the Deutsche Mark against the Yen. The data were provided by Olsen Associates. A waveform dictionary is a class of transfor...
متن کاملDetermining building interior structures using compressive sensing
We consider imaging of the building interior structures using Compressive Sensing (CS) with applications to through-the-wall imaging and urban sensing. We consider a monostatic synthetic aperture radar imaging system employing stepped frequency waveform. The proposed approach exploits prior information of building construction practices to form an appropriate sparse representation of the buildi...

This research presented the use of bilingual dictionary and addressed the EFL translation students' points of view on the use of bilingual dictionary in translating polysemous words (English to Persian). Moreo- ver, it aimed at finding the possible relationship between the effect of using bilingual dictionary by stu- dents in translating polysemous words and their achieved scores. In the study ...
