What is Google Cloud Speech to Text?

Google Cloud Speech to Text converts audio and video into written text using machine learning.

The service integrates with Google Cloud's broader ecosystem, so it works well if you're already using other Google Cloud products. It offers both a free tier and paid options based on usage, which makes it accessible for small projects as well as large-scale operations.
