What to watch out for

Whisper Speech is open source and free, but the license and distribution terms can change as the project updates, so confirm the current terms before you build on it. Setting it up needs technical skill, and you have to manage your own deployment, which may involve real compute and maintenance costs. Speech quality can vary by language and by the text you feed in, so test with your own data. Treat it as a developer and research tool rather than a one-click consumer app, and check that your hardware and environment can run the model. For best results, start with a small test file and review the output carefully before working on anything important.
