Django API Streaming

Implementation of an API to stream audio files for transcription in Django using the REST Framework.

Installation

If you want to try the server inside a virtual environment.

   pip install -r requirements.txt

Usage

Using docker-compose

Update docker-compose.yml to point to your models path under services:stt:volumes.

Build the stack using docker-compose.

docker-compose up -d

Then collect staticfiles.

docker-compose run --rm stt /app/manage.py collectstatic --no-input

Go to http://0.0.0.0/stt/.

Running in a local environment

Before you run the server, you need to update the configuration located at stt_app/config/config.json with the path to your desired models.

{
    "stt": {
      "model" :"path/to/models/output_graph.tflite",
      "lm": "path/to/models/kenlm.scorer",
      "audiofiledir": "/path/to/tmp_dir_audio",
      "audiofilelength": "10",
      "debug": "1"
    }
}

Run the server in local for testing (HTTP).

   python manage.py runserver

Run the server in local for production (HTTPS).

   python manage.py runsslserver
