pocketsphinx how to determine out of grammar words
cmusphinx
Solution
No, this feature is not implemented. For more details see
http://cmusphinx.sourceforge.net/wiki/faq#qcan_pocketsphinx_reject_out-of-grammar_words_and_noises
You can use keyword spotting mode instead to look for a list of keyphrases. You can configure activation threshold for every phrase.
Problem
I am currently using pocketsphix demo (android and visual studio 2010) and I have configured a jsgf grammer like this ``` #JSGF V1.0; grammar Names; public <popular> = muhammad | ahmed | maria | john | kelley | peter | jacob | jason; ``` Whenever I say correct name, it detects it right in most cases but when I say a name not in the list, it still matches something and I do not want that or atleast be able to detect if something was said that was not in Grammar (may be through some score or api of pocketsphinx) I am sure pocketsphinx has it somewhere which I don't know. Please advise. Thanks, Ahmed
