+# MicroslopSam
+
+Run SAPI4 text-to-speech voices on Linux.
+
+Primary approach: a **Winelib host** — a native Linux ELF that uses Wine's
+libraries to load the original 32-bit SAPI4 runtime and TTS engine DLLs.
+
+Voice targets:
+
+- Microsoft Sam / Mary / Mike — MSTTS engine (`msttssyn.dll` + `.vce` data)
+- AT&T Flextalk 2.1 — "Keith Bell" and "Kerry Watson" (`FlexTalk.dll`)
+
+Long-term: replace Wine-provided pieces with own shims (rehost) for a
+pure-native build, and keep a path to a fully portable engine.
+
+## Status (working)
+
+- Winelib host builds and runs: `build/sapi4host.exe` (launcher) +
+  `build/sapi4host.exe.so` (native 32-bit ELF).
+- Voices enumerate and synthesize:
+  - MSTTS: Sam, Mary, Mike (+ telephone and effect variants)
+  - AT&T Flextalk: Keith Bell, Kerry Watson
+- Test output: `build/test_sam.wav` (22.05 kHz), `build/test_Keith_Bell.wav`,
+  `build/test_Kerry_Watson.wav` (11.025 kHz).
+
+## Build
+
+Dependencies (once, as root):
+
+    sudo setup/install-deps.sh
+
+Runtime + MSTTS voices (once):
+
+    setup/setup-prefix.sh
+
+Flextalk voices (once; needs the extracted installer, see `docs/NOTES.md`):
+
+    setup/setup-flextalk.sh
+
+Host:
+
+    # Winelib (native ELF + launcher)
+    winegcc -m32 -O2 -o build/sapi4host host/sapi4host.c -I../reference \
+        -lole32 -luser32 -ladvapi32
+
+    # PE fallback (runs under wine):
+    i686-w64-mingw32-gcc -O2 -static -o build/sapi4host.exe host/sapi4host.c \
+        -I../reference -lole32 -luser32 -ladvapi32 -luuid
+
+## Usage
+
+    setup/run.sh -l
+    setup/run.sh -v Sam -t "Hello." -o sam.wav
+    setup/run.sh -v "Keith Bell" -t "Hello." -o keith.wav -p 100 -s 150
+
+Options: `-v` voice, `-t` text, `-o` output WAV, `-p` pitch, `-s` speed.
+
+## Layout
+
+- `host/sapi4host.c` — host: voice select, pitch/speed, text -> WAV
+- `setup/install-deps.sh` — Wine/Winelib/helpers (root)
+- `setup/setup-prefix.sh` — prefix + SAPI4 runtime + MSTTS engine/voices
+- `setup/setup-flextalk.sh` — Flextalk files + registry
+- `setup/inf2reg.py` — INF AddReg -> `.reg` converter
+- `setup/run.sh` — run helper (prefix + Xvfb)
+- `docs/NOTES.md` — registry/CLSID facts, runtime RE notes, gotchas
+
+## Known issues
+
+- `xvfb-run` is flaky on this host. `setup/run.sh` starts a persistent Xvfb
+  (`:77`) instead; Wine needs a working X display because the runtime creates
+  windows.
+- Flextalk's default pitch/speed report as maximum (250/390) through
+  `ITTSAttributes`; values are still adjustable with `-p`/`-s`.
+- The Flextalk archive lacks `data2.cab`; `unshield -O` extracts `data1.cab`
+  but one tail file (`WatsonUNInstall.dll`) is incomplete.
+
