BatchModeRecognizer

[Sebastian]

Good day everybody,

i want to recognize words/sentences from feature file created by FeatureFileDumper. after read some sphinx documentation, i decided to use BatchModeRecognizer for that purpose.

my questions are:
1. is BatchModeRecognizer good tool for this purpose? are there any better tools or ways to handle this job ?
2. when i tried BatchModeRecognizer, i got these exceptions. what should i check or do to solve it?

C:\sphinx\sphinx4\bld\classes>java edu/cmu/sphinx/tools/batch/BatchModeRecognize

Its a correct tool but prepare it will not work out of box. In your case you have to add wsj jar to classpath.
