You should check out the project and just build a debug version of the TTS yourself. The ant build.xml file should make that very easy, just do the following steps:
1. Check out the project
2. Change the sdk-folder of the build.xml under the tts directory to point at where you have the Android sdk.
3. Start up the emulator (and again, you should do it so that you start up with an SD card image).
4. From the commandline, go to the tts directory and type "ant".
The emulator doesn't contain Market, so I think building your own is the easiest way to get that onto the emulator.

BTW, if you do this on the emulator and you don't hear speech and you get a VERY long dump of green text in logcat, try deleting your SD card image and creating a new one. I've had this happen a few times on the emulator where something goes very wrong with the voice data. Creating a new SD card image forces a redownload of the voice data, so that worksaround the issue. This does NOT happen on actual devices and only happens on the emulator; still trying to figure out what the issue on the emulator is.
