Pull Request: Support Additional Whisper Services (OpenAI Whisper API Integration)

Overview

This pull request addresses issue #137 from the GitHub repository for the grouplang secretary bot, focusing on enhancing the bot's transcription capabilities by integrating the OpenAI Whisper API as an additional voice transcription service. This integration aims to provide improved flexibility, performance, and cost-effectiveness for users depending on their needs.

Summary of Changes

The following key changes have been made:

1. Integration of OpenAI Whisper API:

   • Added functionality to support the OpenAI Whisper API as a new transcription option.
   • Developed a dedicated OpenAITranscriber class to manage audio transcription using the OpenAI Whisper API.

2. Abstract Base Class for Transcription Services:

   • Introduced an abstract class named BaseTranscriber that defines the common interface and shared functionality for various transcription services, including both AWS and OpenAI.

3. Refactor of AWS Transcription Logic:

   • The existing logic for AWS transcription has been refactored into a structured AWSTranscriber class, enhancing code maintainability and clarity.

4. Factory Pattern for Service Selection:

   • Implemented a TranscriberFactory which employs a factory design pattern to dynamically select and instantiate the appropriate transcriber based on the chosen service in the configuration settings.

5. Configuration Updates:

   • Updated the configuration system to allow users to select between the AWS and OpenAI transcription services through the TRANSCRIPTION_SERVICE environment variable. Users can now easily switch between options ('aws' or 'openai') as needed.

6. Bot Handler Modifications:

   • Made necessary updates to the bot handlers, ensuring they use the new factory pattern to facilitate seamless audio message transcription.

7. Documentation Revamp:

   • Revised the README.md file to thoroughly document the new features, configuration settings, and API references, covering both the existing AWS service and the newly added OpenAI service.

Next Steps

• Ensure that all environment configurations are correctly set prior to deployment.
• Conduct thorough testing to verify the functionality and reliability of both transcription services.
• Gather performance metrics and user feedback to inform potential future enhancements.
