## Collection notes

Only the text-to-speech part of Azure AI Speech is entered. The pricing page shows "$-" for every dollar amount (the amounts are filled in by script), so the Standard (S0) pay-as-you-go plan has no price and is not listed. The Free (F0) plan gives 0.5 million Neural characters a month; its dollar price is not stated either. Not entered: voice cloning (Personal voice and Custom voice are limited-access features), commercial use (no sentence found), and whether customer text is used for training (the pages speak about custom-voice training data only). The text of real-time synthesis is not retained.
