Summary

This pull request introduces a function that converts text into spoken audio using Google, Azure, and AWS APIs. To achieve this, the function will receive a request containing essential information such as the chosen provider, the desired language, and the input text. Additionally, the necessary environment variables will be provided, containing the required settings for the chosen provider. The function will return the converted text into audio in the form of bytes.

Details

• README.md contains instructions on how to run the main function.

• main.py contains functions to validate common, requests, and perform speech synthesis Google, Azure, and AWS.

• requirements.txt contains Python packages and dependencies used for our build.

• test_main.py contains unittest for the main.py file with various scenarios like happy paths, value errors, unexpected exceptions etc. test_main.py uses result.txt as a sample speech synthesis result.
