Hi,

having some accuracy problems, im still learning how to get everything to come together.

im using this sample audio file http://www.canirun.co.uk/bob.wav

the output im getting is: it's art at larchmont slash reader
expected output: get started with google dot com slash reader

my config (using lattice demo):

<?xml version="1.0" encoding="UTF-8"?>

ok im starting to get it, i've changed the config to:

<property name="absoluteBeamWidth" value="500"/>
    <property name="relativeBeamWidth" value="1E-80"/>
    <property name="absoluteWordBeamWidth" value="20"/>
    <property name="relativeWordBeamWidth" value="1E-60"/>
    <property name="wordInsertionProbability" value="0.2"/>
    <property name="languageWeight" value="4"/>
    <property name="silenceInsertionProbability" value=".1"/>
    <property name="frontend" value="epFrontEnd"/>
    <property name="recognizer" value="recognizer"/>
    <property name="showCreations" value="false"/>

and i now get: get started at gogel ah tromp slash reader

do i simply add:

GOOGLE.COM G OW G AH L D AA T K AA M

to the dictionary (to get it to recignise google.com)? I tryed it but it doesn't seem to work...do i also have to include it in the arpa language model as well (google.com)?

thanks.

Yes

I also recommend you to read a tutorial which explains all the problems like you are asking about
