I'm running Sierra (10.12.5) and I've been using the text-to-speech feature to read news articles. The system stumbled over the phrase "defeat ISIS" today, saying DEH-feh-CHURring EYE-sis. The system can pronounce "defeat" and "ISIS" correctly as separate words, but if I put them together, "defeat" gets the incorrect pronunciation.
While probing this oddity further I've discovered that:
- Of the English speaking voices, only the Samantha voice has this flaw.
- The DEH-feh-CHURring pronunciation occurs if you follow "defeat" with any word at all. Even random strings produce the error.
Is this user-fixable short of giving up on the Samantha voice?
