I'm looking for API with Text-to-Speech, and, more importantly, Speech-to-Text (I need it to return string). Preferably it should be on C++, C#, Java or Python, but that's not crucial And it would be great if it'd have its own database, so there'd be no need in long learning
I have worked on a lot of Text to speech and speech to text projects. This is for Python by the way. Most apis have bad free plans and decent paid ones. Google text to speech is very good and well organized on the google cloud. https://cloud.google.com/text-to-speech For your speech to text, I would use the built in "SpeechRecgonition" api in the Pycharm interpreter.
