About

This is a demonstration for Kaldi on Android

Usage

Simply import the project into Android Studio and run. It will listen for the audio and dump the transcription.

To use this library in your application simply modify the demo according to your needs - add kaldi-android aar to dependencies, update the model and modify java UI code accodring to your needs.

Development

This is just a demo project, the main setup to compile kaldi-android library AAR is available at kaldi-android. Check compilation instructions there as well as development plans.

Languages

Models for different languages (English, Chinese, Russian) are available in Releases section. To use the model unpack it into kaldi-android-demo/models/src/main/assets/sync/model-android. More languages gonna be ready soon.

Updating grammar and language model

To run on android model has to be sufficiently small, we recommend to check model sizes in the demo to figure out what should be the size of the model. If you want to update the grammar or the acoustic model, check the script mkgraph_lookahead_arpa.sh from lookahead branch at our kaldi fork or from submitted pull request. Hopefully that pull request will be merged soon and graph can be compiled with kaldi master.

You can’t perform that action at this time.
