Basically, the role of the transcription controller is to provide a simple interface for working with the different modules of the system.

The role of the TranscriptionController is to meet the user's need for our system to have a simple interface, and to simply pass an input to receive a TranscriberContext.

So for that, the TranscriptionController directly needs to use the different services available (Downloader, Convertor, Transcriber)

Here is an example of what the TranscriptionController instantiate and call

graph TD;
    TranscriptionController-->|Instantiate it on every transcription|Downloader;
    TranscriptionController-->|Instantiate it on every transcription|Convertor;
    TranscriptionController-->|Instantiate it once|Transcriber;
