As this line shows:

0x00007fe9bc0bd21d in speex_resampler_destroy () from /usr/lib/x86_64-linux-gnu/libspeexdsp.so.1

I checked the Freeswitch logs, my call is using PCMU 8KHz and It was getting resampled for the mod_google_transcribe bug to 16KHz, so i have changed all the hardcoded values in the google_glue.cpp from 16000 to 8000 and recompiled the module. This has fixed my issue for a specific call. but still need to fix this.
