...use Universal Extractor to break apart the ginormous install file ...
Terry, thanks for that tip.
I found three folders related to SAPI and TTS:
I know TTS21 provides the Anna voice so I ran \MSTTSEng_21
\MSTTSEngine.msi and it installed "Microsoft English TTS Engine
" (visible in Control Panel's Programs list). The Speech applet listed Microsoft Anna but the voice sounded clipped. I proceeded to install \MSTTSEng_20
\TTS_Nested.msi. After it completed, I couldn't find anything new in the Programs list. However, Anna now sounded correct.
I used Universal Extractor to take apart the SAPI installer (SAPI51.msi) and it contains Microsoft Sam, Mike, and Mary. I ran the SAPI installer but it did not add any new voices. In fact, the installer appears to be unconfigured (i.e. does an installation of "Default" and the license agreement is a bare-bones template). It's a shame this does not work, because I know of only one other way to install these voices and that's using the SAPI 5.1 SDK (about 80Mb of baggage).
On two other PC's, I ran the installers found in MSTTSEng_20 and MSTTSEng_21 with good results. I think these two installers represent all that is needed to install the Anna voice and its TTS engine.
