Introduction to AI speech concepts: Review

“Exercise - Use Speech Synthesis” includes a bizarre line: “No lab VM is associated with this exercise.” So the entire hands-on part is just you imagining how you would use the service. What a letdown after clicking through all the concepts.

This whole thing feels like the introductory chapter of a textbook that got separated from the rest of the book. It does an okay job defining the absolute basics: speech-to-text, text-to-speech, what phonemes and visemes are. The diagrams are clean. It's a quick read, maybe 20 minutes if you don't dawdle. But it never gets you anywhere near a real tool. There's no API call, no sample code snippet, not even a demo you can interact with. It's all just descriptive text talking about what's *possible* with the Azure Speech service.

I get that it's an 'introduction to concepts,' but even for that, it's thin. I was hoping for at least a pointer to a GitHub repo or a minimal Python script to try out. The other modules in the path, like 'Create speech-enabled apps', seem to be where the actual work is. This one is just the gate you have to pass through. It feels like required reading before you're allowed into the lab. It's fine for what it is, but just know you won't build anything here.
