Hi,

Am trying to train an acoustic model for a native language. Training data set is ~1 hour. After running sphinxtrain run, I see some warnings + errors, and finally training stops. Some extracts from the warnings and errors are shown inline [1]. Complete log file is attached. Any idea what is going wrong here?

You need to fix the first warning

[Izza]

Hi Nickolay,

Thanks for the input. I fixed the first warning set, and ran again. Then came across another error [1]. As per the troubleshooting tips given in [2], tried with CFG_FORCEDALIGN set to 'true'. That reduced the number of errors [3], but then got the error mentioning sphinx3_align script is not found [4]. I took a checkout of the cmusphinx githug repo, and tried building sphinx3 (I had built sphinxbase-5prealpha earlier). However, hit some compilation issues [5]. Suspect this is because of an incompatibility in the sphinxbase and sphinx3 I tried to compile.

Why do I still get ERRORs after setting CFG_FORCEDALIGN to 'true'? Also, could you please point me to a source location/released version of sphinx3 compatible with sphinxbase-5prealpha.

Thank you.
