Installation

1. Clone the repository:

   git clone https://github.com/umarquez/goai_transcriber.git
   cd goai_transcriber
   

2. Set up environment variables: Create a .env file and add your OpenAI token:

   APP_OPENAI_TOKEN=your_openai_token
   APP_WORKING_PATH=./audios
   

Running the Application

Running the Application Locally

Standard Application

1. Build and run the application:

   go build -o bin/app cmd/app/main.go
   ./bin/app
   

2. Transcribe audio files:

   • The application reads the content of the ./audios directory.
   • If there are .m4a files, they are converted to .mp3 due to an error from the OpenAI API processing .m4a files.
   • The transcription result is written to the same directory with a .txt extension.

API Version

1. Generate Swagger documentation:

   swag init --parseDependency --parseInternal -g cmd/api/main.go -o ./docs
   

2. Build and run the API:

   go build -o bin/api cmd/api/main.go
   ./bin/api
   

3. Transcribe audio files via API: Use a tool like curl or Postman to send a POST request to the /transcribe endpoint with your audio file.

   Example curl command:

   curl -X POST "http://localhost:8080/transcribe" -H "accept: application/json" -H "Content-Type: multipart/form-data" -F "file=@path/to/your/audiofile.m4a"
   

Running the Application Using Docker

Standard Application

1. Build and run the application using Docker:

   docker-compose -f deployment/docker-compose.yml up --build
   

2. Transcribe audio files: Place your audio files in the audios directory and the application will automatically process and transcribe them.

API Version

1. Build and run the API using Docker:

   docker-compose -f deployment/docker-compose.api.yml up --build
   

2. Transcribe audio files via API: Use a tool like curl or Postman to send a POST request to the /transcribe endpoint with your audio file.

   Example curl command:

   curl -X POST "http://localhost:8080/transcribe" -H "accept: application/json" -H "Content-Type: multipart/form-data" -F "file=@path/to/your/audiofile.m4a"
   

API Documentation

The API is documented using Swagger. Once the application is running, you can access the documentation at:
