5526 Speech Recognition Application of Sphinx-4 Yuan Hao

SPHINX-4 Providing a more flexible framework for research in speech recognition Written entirely in the Java programming language

ZipCity A simple application for Sphinx-4. ZipCity listens for the zip code and show the location related to the zip code.

ZipCity What should we do if we don’t know the zip code, but we know the name of the city? Modify ZipCity!

Things we should modify ZipCity.configer.xml – This document demonstrate the model and dictionary we use. Now, it only can recognize digit. ZipCity.gram ZipRecognizer.java ZipDatabase.java

ZipCity.configer.xml Change the dictionary path. – <property name="dictionaryPath" – value="resource:/WSJ_8gau_13dCep_16k_40mel_130Hz_ 6800Hz/dict/cmudict.0.6d"/> Change the filler path. – <property name="fillerPath" – value="resource:/WSJ_8gau_13dCep_16k_40mel_130Hz_ 6800Hz/dict/fillerdict"/>

ZipCity.configer.xml Change the acoustic model. – <property name="location" – value="resource:/WSJ_8gau_13dCep_16k_40mel_130Hz_ 6800Hz"/> – <property name="modelDefinition" – value="etc/WSJ_clean_13dCep_16k_40mel_130Hz_6800H z.4000.mdef"/> – <property name="dataLocation" – value="cd_continuous_8gau/"/>

ZipCity.gram Adjust the grammar – public = ; – = New-york | Cocoa | San-Francisco | Chicago | Houston | San-diego | Tallahassee | Titusville | Orlando | Miami | computer ;

ZipRecognizer.java Add the city name we list in ZipCity.gram – Recognizer returen the value of “digitMap.put()”, so we should add the city name in digitMap code. – digitMap.put("chicago", "chicago"); digitMap.put("san- francisco", "san-francisco"); digitMap.put("new-york", "new-york");

ZipDatabase.java Look up the info of city using city name instead of using zip code. – zipDB.put(city, new ZipInfo(zip, city, state,latitude, longitude))

Done! Let’s see what happened!

Supplement The grammar should be complete, and so do the dictionary. Now, it just contain 10 cities name. This application also can recognize word, even that word is not a city name.
