Update timeline

  1. investigating Feb 19, 2026, 06:21 PM UTC

    TTS generations using pronunciation dictionaries produce incorrect audio (some structured metadata is read out in the speech). Workaround for affected customers: use `sonic-3` instead of `sonic-3-latest`.

  2. investigating Feb 19, 2026, 06:45 PM UTC

    We have rolled back the bad deploy and pronunciation dictionaries are once again working with `sonic-3-latest`.
