+# Speech to text transcription
+
+
+## Objective
+This project aims to transcribe audio file using [openai-whisper](https://github.com/openai/whisper) model. Users can also enter a valid YouTube URL for transcription.
+
+
+## Public Endpoints for Deployed App
+
+Application is deployed on streamlit cloud [here](https://transcribe-whisper.streamlit.app/).
+
+You can deploy it on your own easily and (possibly) free of charge on cloud. Scroll down to `Docker Playground Cloud Deployment` in `Deployment` section.
+
+
+## Code Structure / Services
+- `app` - Complete application code built in streamlit.
+- `packages` - List of linux dependencies required to deploy code on streamlit cloud.
+- `docker-compose` - Compose file which starts application.
+
+
+## Deployment
+- Local deployment
+    - Install Docker. Instructions available [here](https://docs.docker.com/engine/install/). Make sure docker is up and running before proceeding.
+    - Install Git. Instructions [here](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git).
+    - Clone repo and run compose
+    ```
+    git clone https://github.com/uditmanav17/ML-Projects.git && cd ./ML-Projects
+    git switch whisper && cd ./speech-to-text
+    docker compose --profile app up
+    ```
+    - `--profile app` will start on `localhost:8501` port.
+
+- Docker Playground Cloud Deployment
+    - Navigate to [docker playground](https://labs.play-with-docker.com/).
+    - Login using your docker account. Click Start. This will direct you to a new page.
+    - Click `Add New Instance` on left pane. Then run following commands in terminal -
+    ```
+    git clone https://github.com/uditmanav17/ML-Projects.git && cd ./ML-Projects
+    git switch whisper && cd ./speech-to-text
+    docker compose --profile app up
+    ```
+    - To access application, click on port numbers next to `OPEN PORT` button to visit application.
+
+
+## Future work/ Improvements
+- Add download transcription as subtitles `.srt` file.
+- Implement streaming transcription.
