The brief will begin by outlining the challenges associated with Keyword Spotting within large speech databases using dynamic keyword vocabularies. It will then continue by highlighting the various market segments in need of KWS solutions, as well as, the specific requirements of each market segment. The work also includes a detailed description of the complexity of the task and the different methods that are used, including the advantages and disadvantages of each method and an in-depth comparison. The main focus will be on the Phonetic Search method and its efficient implementation. This will include a literature review of the various methods used for the efficient implementation of Phonetic Search Keyword Spotting, with an emphasis on the authors? own research which entails a comparative analysis of the Phonetic Search method which includes algorithmic details. This brief is useful for researchers and developers in academia and industry from the fields of speech processing and speech recognition, specifically Keyword Spotting. 410 0$aSpringerBriefs in electrical and computer engineering.$pSpeech technology. 606 $aDatabase searching 606 $aKeyword searching 606 $aNatural language processing (Computer science) 606 $aSpeech processing systems 615 0$aDatabase searching. 615 0$aKeyword searching. 615 0$aNatural language processing (Computer science) 615 0$aSpeech processing systems. 676 $a025.04 700 $aMoyal$b Ami$4aut$4http://id.loc.gov/vocabulary/relators/aut$01058999 702 $aAharonson$b Vered$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aTetariy$b Ella$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aGishri$b Michal$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiFhGG 801 1$bMiFhGG 906 $aBOOK 912 $a9910437895203321 996 $aPhonetic Search Methods for Large Speech Databases$92503583 997 $aUNINA
