I downloaded another TTS pack from Microsoft Speech Platform - Runtime Languages (Version 11), but in the speech properties this pack doesn't show up.

The image bellow lists all packs installed, which came by default in my Windows 8 installation.


But it is not supported on windows 8, so how can I install more packs?

That page states that those are only language data files, most likely for MS SAPI developers. Third party voices/TTS engines seem to be much larger downloads, but TBH I've never tried any besides the 2 L&H voices for XP that MS provided as free downloads. –  Karan May 3 '13 at 23:39
Also want to know how to add German to this. –  DebugErr Dec 14 '13 at 16:11
I didn't realized that Windows finally can speak so many languages! –  Kamil Sep 1 '14 at 14:11

Add new language in Control panel and then download language pack in there.

Welcome to Superuser! This answer is a little short on detail, could you please expand it a little? Thanks –  David Mar 25 '14 at 18:58
This is for Windows 8.1 - first 2 steps needed windows.microsoft.com/en-us/windows-8/add-language-keyboard . There are almost identical language settings in desktop Control Panel for both Windows 8 and 8.1 –  Ivan Ičin Mar 25 '14 at 22:30

Just use the tutorial on this page:


This involves manual edits to your registry. If you mess it up, don't blame me. Do at your own risk.

Step 1 --------------------------------------------------------------------------

Install the Speech Platform v11

a) go here: http://www.microsoft.com/en-us/download/details.aspx?id=27225
b) click "Download"
c) select the "x64_SpeechPlatformRuntime\SpeechPlatformRuntime.msi"
d) run the installer (duh :P)

Step 2: --------------------------------------------------------------------------

Get the alternate voices

a) go here: http://www.microsoft.com/en-us/download/details.aspx?id=27224
b) click "Download"
c) select the voice files you want. They are the ones that have "TTS" in the file name. 

There are 6 English (all female). I have not listened to the other languages, so I dont know how they sound. GB_Hazel and US_ZiraPro are IMO the better sounding voices.


d) run the installers for each (duh :P)

Step 3: --------------------------------------------------------------------------

Extract the registry tokens

a) Open Regedit
b) Under - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech Server\v11.0\Voices - right click the "Tokens" folder and export. Save this file to your desktop as voices1.reg so it will be easy to find later.
b) Under - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Speech Server\v11.0\Voices - right click "Tokens" and again export it, again to the desktop. Call it voices2.reg.

Step 4: --------------------------------------------------------------------------

Edit the voices1/2 files

a) open Voices1.reg in Notepad.
b) press "cntrl + H"
c) enter \Speech Server\v11.0\ into the "Find What" field
d) enter \Speech\ into the "Replace With" field
e) click "Replace All"
f) Save File
g) Repeat a-f with the Voices2.reg file

Step 5: --------------------------------------------------------------------------

Merge the new Registry files into your registry

a) double click to "run" both Voices1.reg and Voices2.reg
b) Click "Yes" when it prompts

You should now have access to the new voices in Voice Attack, and in the Windows TTS options menu.

This process may also work with other voice packs.
