update the model for the android demo app #1673
Comments

You seem to compile big model, do you try to update small model with it? Those are not compatible. Small model compilation package is in colab (see vosk-adaptation.ipynb file) |
|
I'll give the notebook a try. How could I take the output of above and make it work with the android demo? |
|
You put it inside vosk-model-en-us-0.22-lgraph https://alphacephei.com/vosk/models/vosk-model-en-us-0.22-lgraph.zip |
|
It is also recommended to test on desktop with python first then play with the device |
|
Tried the notebook. Seems that the decode is failing. I also get the same ivectors warning on the Dockerfile version |
|
Ah I See need a GPU collab |
|
Nope was using a t4 GPU. Seems that Colab now uses version 12 !lsb_release -a No LSB modules are available. |
|
Add this to the top of the notebook to fix cuda issue: |
|
Thanks, we probably need to recompile kaldi to use cpu |

I am having exactly the same problem. We have built using vosk-model-small-en-us-0.15-compile-colab. Successfully added words to the dictionary and tested in Python. Where is works perfectly. However we now also want it work inside a browser. So we have used npm install vosk-browser and whilst the default vosk-model-small-en-us-0.15 works. Our newly created model updated with a few words does not. We have enabled the commented out code in compile-graph.sh to see if we can produce them. This does as earlier mentioned allow the Python version to work with the new words. # Lookahead part goes OOM
utils/mkgraph_lookahead.sh \
--self-loop-scale 1.0 data/lang \
exp/tdnn data/en-us-mix.lm.gz exp/tdnn/lgraphIt does create the HCLr.fst and Gr.fst files. We move them over and the library in javascript fails with this message. I have attempted to copy in the ivectors but noted that they have not changed. I have also noted that hte HCLr.fst and Gr.fst are smaller in size. I do have a Cuda machine so we can easily run it. But I haven't had any message saying one was required. Hope you can help us! We love the project. |
This file should not be there. Please check files of the original model. Please delete old files from filesystem, they can break things. |

Thanks for your suggestion. I have removed global_cmvn.stats. I don't have in the logs "Reading CMVN stats." But it still does not seem to work. Using the vosk-model-small-en-us-0.15.zip I have tried to rebuilt the same format. We must be close as the model works in Python. This is based on the vosk-model-small-en-us-0.15-compile-colab.tar.gz - This file is dated 17th August 2022 is there an updated version? |
It is the latest version and it should work fine. You need to provide an updated log and show the model files on your filesystem. |
|
Here are the logs as requested. File structure is this:
What is confusing is that Gr.fst and HCLr.fst are smaller than the one compiled. Even if we change nothing it seems to build smaller. |
it is ok
Ivector folder misses some file (final.ie for example) |
Dockerfile.txt
Trying to add domain specific words for use with android demo. I am using the attached docker file as the build machine.
After a docker build and docker run it will successfully run the
./compile-graph.shfollowed bydecode.shAfter copying in the files to the model in the android project and running, it crashes. Maybe I am not getting all the proper files. Seems that guides suggest only needing to update
Gr.fstandHCLr.fst???Looking through the other issues, I know that you recommend using the repos from alphacep, however when using those in the dockerfile it fails to compile.
I have also attached the file list from the compile and decode.
files.txt
Appreciate any help.
