Setup

1. clone the repo.

git clone git@github.com:amankrayush/speech-assistant-distro.git

2. download model for languages (To recognize speech and convert it into text for particular language)

sh ./scripts/download_models.sh "english hindi"

3. update the network name in docker-compose.yml file as per your requirement.

networks:
  default:
    name: bahmni-docker_default
    external: true

Note :

• Speech Assistant application is intergrated with Bahmni, that's why network name is mentioned as 'bahmni-docker_default'
• Remove the networks field if you don't need external network.
• If external network is required, update it with external network name and it should present in the docker.

4. make applications up (make sure models are available - mentioned in step 2)

docker-compose up -d
