simple wav decoding don't work

[by-tech]

En_1272-128104-0000.zip installation and compile was success. But when trying a simple wav english file, there's no recognition.

to be sure that file is correct , i used "ffmpeg -i En_1272-128104-0000.wav -f s16le -ar 16000 -ac 1 En_1272-128104-0000.raw"

what i have missing ? thanks to help

I am also facing same issue

Me too #31 What version of Kaldi are you using? Something recent? And what version did you use to build your models? It works for me if I use a model from about a year ago.

Back in #11 I posted a tar of some test code (see https://github.com/api-ai/asr-server/files/828349/APIAI_Server.tar.gz) that allows you to input xx.raw files directly. I just tried that code again today against Kaldi pulled from Github today and it worked for me (note that to compile you need to remove kaldi-thread.a from src/Makefile). The output for En_1272-128104-0000.raw was...

{"status":"ok","data":[{"confidence":0.897815,"text":"MR QUARTERS THE APOSTLE OF MIDDLE CLASS AND WE'RE GLAD WELCOME HIS GOSPEL"}]}

You might try that code. It's a bit hackerish but if you compile and execute run.sh it'll decode the included test.raw. Be sure to change the location of the model as defined at the top of run.sh.
