Subject: [PATCH] =?UTF-8?q?tweak(mi-voice):=20quiet=20feminine=20=E2=80=94?=
 =?UTF-8?q?=20Emma,=20volume=200.25,=20neutral=20pitch?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User preference: quiet + feminine. Swap Andrew (male) for Emma
(calmer, softer female than Aria). Drop volume 0.3 -> 0.25, reset
pitch to natural (deeper shift made it sound male). Rate stays slow.
