Android: Speech Recognition without using google server

Question

I want to develop an Speech recognizer in android, which should work in offline. As the android's built-in speech recognizer uses google server which needs internet, i want an alternative which works in the absence of internet.

Please suggest me some way to achieve the above feature.

Solution

We used to recommend pocketsphinx, but now more advanced technology based on Kaldi toolkit is available.

The demo is here: Vosk API, you can simply load it in Android Studio and run. Full disclosure: I am the primary author of Vosk.

It supports speech recognition in 7 major languages - English, Chinese, Spanish, Portuguese, German, French and Russian.
