Cannot use deepspeech -e to get timestamp

DeepSpeech
#1

Maybe I miss something, but I look at this merged pull request https://github.com/mozilla/DeepSpeech/pull/1974/files

And I updated my version to 0.5.0a5, but when I try use -e i got this error

usage: deepspeech [-h] --model MODEL --alphabet ALPHABET [--lm [LM]]
              [--trie [TRIE]] --audio AUDIO [--version]
deepspeech: error: unrecognized arguments: -e
"Could not create model" when running either native or python

Looks like you’re using the Python package, but the timing information is currently only exposed in the native binary, which can be found in the appropriate native_client package in the release: https://github.com/mozilla/DeepSpeech/releases/tag/v0.5.0-alpha.5

Can you please tell how to use native client package for ubuntu.I too tried -e with the code deepspeechtiming
but it didn’t worked

#4

Can you share more details on what you do exactly ? The work from @dabinat has been merged a long time ago, but the parameter has been changed to --json.

Json/csv file is not generated. I’m getting the following output:

--json is only available on the C++ deepspeech binary. Are you using this one? I used --json no later than yesterday …

#7

Do you have a sample C++ code that consumes native deepspeech binaries?

#8

You can call them from the command-line. Just download the native client binary for your platform and use the following command:

deepspeech --json --model models/output_graph.pbmm --alphabet models/alphabet.txt --lm models/lm.binary --trie models/trie --audio audio.wav

Here’s how to download the command line client: https://github.com/mozilla/DeepSpeech#using-the-command-line-client

Thank you guys!

I got confused about usage of native vs. python bindings. My bad.

Plz explain it to me how to do it as I am still stuck with it and not getting the json file.I am using ubuntu and downloaded the nativeclient b using

python3 util/taskcluster.py --target .

And then i tried running this

deepspeech --json --model models/output_graph.pbmm --alphabet models/alphabet.txt --lm models/lm.binary --trie models/trie --audio audio.wav

But i am still getting this error

usage: deepspeech [-h] --model MODEL --alphabet ALPHABET [–lm [LM]]
[–trie [TRIE]] --audio AUDIO [–version] [–extended]

Please read answers above.

Hey @lissyx .I tried the steps mentioned above.But it still showing the error when I command
deepspeech --json --model models/output_graph.pbmm --alphabet models/alphabet.txt --lm models/lm.binary --trie models/trie --audio munsters.wav

deepspeech: error: unrecognized arguments: --json

It means deepspeech is not the C++ binary, but the Python. If you extracted like you did, you need to ./deepspeech
