Downloading Microsoft SAPI

If you have any questions, just email us at support@nextup.com.

About SAPI
SAPI is a standard Speech Application Interface developed by Microsoft.  Most Speech programs
and voices, including all NextUp.com products and voices, use this microsoft speech interface to allow the program and voices to work together. 

SAPI4 is an older version of the standard, supported by a wider variety of voices, especially older voices.  A newer version of this standard, SAPI5 is supported by most of the newer voices, with some voices, such as AT&T Natural Voices supporting both interfaces.  NextUp.com products support both SAPI4 and SAPI5.

Most versions of windows come with either SAPI4 or SAPI5 installed already, but this is not always the case.  There are times when you may need to install one or both of these on your computer in order to allow Text To Speech programs to work, or to take advantage of some features.

If you have any questions on this, please let us know at support@nextup.com.

Downloading and installing SAPI4
SAPI4 is not typically installed on computers, although some speech programs will install it automatically.  To install SAPI4, download and run the installation program below.  NOTE: because SAPI4 is an older standard, on some newer versions of windows, you may see notices during install about installing older files over newer ones.  It is important that you answer "No To All" to this question.
