Wait until you see Azure. Apparently you need to create either an "Azure OpenAI" or a "Microsoft Foundry", where AFAIK (got an email last week) Foundry now includes everything AI including "Azure OpenAI", the former "Cognitive Services" (for speech, computer vision and other stuff) and inference on non-OpenAI models. But wait, because once you create that, you are told to go to another portal (ai.azure.com) where you get an "old" foundry experience and anew one that can't be enabled for every project. Oh, wait, did I mention there apparently used to be a "Foundry" and a "Foundry Project"? Oh, and all those apparently work with a single API key, unless (I guess) you set up authentication with the Azure SDK, which makes you go back to Azure Portal (or maybe Entra ID?).
All of that while trying to explain to your non-technical boss how he can browse the voices available at "the Azure thingy" to pick his favourites to then pick and use in the project due relatively soon. Since, of course, you told him the original Cognitive Speech Services (or Speech Services, or Cognitive Services-Speech, or whatever they decided to call it on that specific page) semi-public URL where he could browse the gallery was "speech.microsoft.com" which is now semi-dead with awful loading times that seem some server issue and has been happenning for a few months now. Or tell them to go to the "new foundry" where he might not be able to find the resource or might not have stuff in the regions you were using up until then, or whatever crap this 3.56 trillion-dollar company decides to throw at you to prevent you from using their services.
And all of this is the exploration phase, where you just use the GUIs and copy things around until they work. Then you need to figure out what you did (and more importantly, where) to be able to write some Terraform/OpenTofu or Bicep or similars to try and keep the environment replicable to avoid the excruciating pain of repeating every single step you followed to get it on a working state.
At the very least, Google was nice enough to launch Vertex AI inside GCP for enterprises that have figured that out, and then Google AI Studio as an almost completely separate thing that only is bound to Google Cloud for billing purposes, similar to how Firebase is integrated too.
