Confidence score per word

We added a word-level confidence score to help you identify words that might have been transcribed incorrectly. Use the word confidence score to determine where to focus when building an application.

Profanity filters

We added prebuilt word filtering using a curated list of profanities. You can either mask, remove, or tag profanities.
