+Offline Speech Recognition using Vosk (Kaldi-ASR) : meta-offline-voice-agent
+=========================================================================
+
+meta-offline-voice-agent is the AGL Layer using Vosk API based on Kaldi ASR Toolkit to enable Offline Speech Recognition capabilities for Automotive Grade Linux.
+
+
+WIP
+========
+The layer in its current state contains the Vosk library, and is capable of recognizing speech, as verified from the test scripts contained in https://github.com/alphacep/vosk-api/tree/master/python/example.
+
+### Working features:
+- [vosk-api (python)](https://github.com/alphacep/vosk-api/tree/master/python)
+- [vosk-websocket-server](https://github.com/alphacep/vosk-server/tree/master/websocket)
+
+
+Testing vosk-api on AGL
+======================
+
+### 1. Initializing the build environment:
+
+The `agl-offline-voice-agent` feature needs to be enabled when including aglsetup.sh:
+
+```shell
+$ source meta-agl/scripts/aglsetup.sh -m qemux86-64 -b build-voice-qemux86-64 agl-demo agl-offline-voice-agent ${AGL_META_PYTHON}
+
+$ bitbake agl-demo-platform
+```
+
+### 2. Running the image:
+
+```shell
+$ runqemu tmp/deploy/images/qemux86-64/agl-demo-platform-qemux86-64.qemuboot.conf kvm serialstdio slirp publicvnc audio
+```
+
+### 3. Run the test with ptest-runner:
+
+```shell
+$ ptest-runner python3-vosk-api
+```
+
+### Currently supported targets:
+- QEMU x86-64: Work in progress.
+
+Maintainers:
+- Aman Arora <aman.arora9848@gmail.com>
