I am starting to do research for a project, and I already found way too many tools to use, but it's hard to judge their pros and cons with no experience. I would love to either know where could I get a professional opinion on the matter of which software or API to pick (I'm not going to outdo someone with years of experience by simply doing a few weeks of research), or get some opinion of what qualities and properties a program should have to be considered.
My project consists of .wav files, recorded in a professional studio set up to get as much quality and as few interferences as possible, and I would like a reliable tool to put that in text (meaning, I give it the audio file, it returns it in some format of text file). Ideally this would be done so later on I can automate the task, but that's secondary.
The language is going to be Spanish (maybe that gives some trouble?), and the idea is to analyze the outputs, frequenzy, relationship between different recordings and so on, that's why I am worried about accuracy.
