But consulting makes special demands on temperament, skills, and experience. To determine whether consulting is for you, you must first understand a little about the various activities called by that name. Then you must carefully examine your emotional needs and life situation as well as the skills and experience you can bring to the marketplace. Then you must realistically compare them to the demands and rewards of the particular variety of consulting you wish to consider.","PeriodicalId":339281,"journal":{"name":"Electro International, 1991","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128609535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Robust Syllable Segmentation Of Continuous Speech Using Neural Networks","authors":"A. Noetzel","doi":"10.1109/ELECTR.1991.718279","DOIUrl":"https://doi.org/10.1109/ELECTR.1991.718279","url":null,"abstract":"We describe a multilayered a neural network structure for continuous speech recognition, based on the isolation and identification of syllables. The first layer is a neural network, trained by unsupervised learning, that detects syllable boundaries and provides a representation of the phonetic content of each syllable. The next layer provides a phonernic representation of the syllable. Each cell of the third layer represents a particular syllable. Multiple cell activations at this layer represent the syllables of an utterance: a phrase or a multisyllabic word. The temporal-discriminant cell, whose activation depends on the sequence of activations at its inputs, is used to disambiguate the pattern in the syllable-cell layer. Each cell of the the fourth layer represents a particular word or phrase. Because a syllable cannot be precisely defined in phonetic terms, and because of the variations of articulation and the boundary effects of adjoining words, different syllables will be identified in different utterances of a word. The neural network structure presented here has a procedure for incorporating alternate representations of words, based on the variations of syllabification that occur in connected speech. The procedure is activated by the misrecognition of a particular word or phrase during supervised learning. A broad class of alternate syllabifications, including the migration of a consonant from syllable-final to syllable-initial position (of the following syllable), are encompassed by a single training step. The learning procedure is demonstrated through simple examples.","PeriodicalId":339281,"journal":{"name":"Electro International, 1991","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115636006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system is called DiSCO, for Distributed Switching with Centralized Optics. DiSCO switches inter-module voice calls and inter and intra-module video calls over time multiplexed network paths through its photonic center-stage. These photonic network paths are transparent to data and are thus independent of transmitter and receiver bit rate. They are called Universal Time-Slots. The photonic center-stage application, its dilated Benes network architecture, and DiSCO's Time-Space-Time system architecture are well matched with today's lithium niobate guided-wave directional coupler technology.","PeriodicalId":339281,"journal":{"name":"Electro International, 1991","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115646662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
