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

opps im not using wsjLoader (just forgot to name it properly in config) im using the latest voxforge 0.4 sphinx model.

--- (Edited on 11/10/2011 7:00 am [GMT-0600] by ) ---

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

<!-- ******************************************************** -->
    <!-- frequently tuned properties                              -->
    <!-- ******************************************************** -->
    <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.
