Articulatory speech synthesis currently has two perspectives. (i) Technical perspective: Due to progress in common computer hardware (general increase in computation rate) and software (usability of compilers and simulation software) it is now possible to develop comprehensive phonetic models of speech production reaching nearly real-time for the calculation of acoustic speech signals.

Two experiments examined whether perceptual recovery from Korean consonant-cluster simplification is based on language-specific phonological knowledge. In tri-consonantal C1C2C3 sequences such as /lkt/ and /lpt/ in Seoul Korean, either C1 or C2 can be completely deleted. Seoul Koreans monitored for C2 targets (/p/ or / k/, deleted or preserved) in the second word of a two-word phrase with an un...

It is traditionally assumed that various sources of linguistic knowledge and their interaction should be formalised in order to be able to convert words into their phonemic representations with reasonable accuracy. We show that using supervised learning techniques, based on a corpus of transcribed words, the same and even better performance can be achieved, without explicit modeling of linguist...

A comparison of two pitch detection algorithms using frequency domain analysis is presented. The algorithm showing the best results based on a perfomance evaluation done by a phonetician will be selected for use in an automatic speech recogni tion (ASR-) system based on the acoustic phonetic approach using knowledge-bases with an expert system. The first algori thm is the Seneff pi tch detectio...

A large vocabulary isolated word recognition system based on the hypothesize-and-test paradigm is described. The system has been, however, devised as a word hypothesizer for a continuous speech understanding system able to answer to queries put to a geographical database. Word preselection is achieved by segmenting and classifying the input signal in terms of broad phonetic classes. Due to low ...
