Hello Mattaniahvanderford,
Thank you for posting your query on Microsoft Community forum.
In Windows XP and Windows 2000 you had the TTS voice known as Microsoft SAM. In these earlier versions, Microsoft Mike and Microsoft Mary were the optional male and female voices respectively, which were available for download from the Microsoft website. But these did not work on the latter Windows versions.
Windows Vista and Windows 7 introduced us to Microsoft Anna the new Text-To-Speech voice replacement. The Chinese releases of Windows 7 had Microsoft Lili. Now in Windows 8 you have Microsoft David, Microsoft Hazel or Microsoft Zira as the default voices of the operating system.
Sorry, to inform you that we will not be able to help you to get Microsoft SAMon Windows 8. However, if you still want Microsoft SAM then in that case you might need to use your search engine to find some third party application or software which can provide you that.
Important: Using Third Party Software, including hardware drivers can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the use of Third Party Software can be solved. Using Third Party Software is at your own risk.
