Text To Speech Engines

Audio Caller ID uses a Text To Speech (TTS) engine to announce incoming callers.  If you do not currently have a TTS engine, you can download one for free from this page.  To find out if you already have a TTS engine installed, select "File / Options... / Audio" from within Audio Caller ID.  If you have a TTS installed you will see a list of available voices.

Audio Caller ID supports both SAPI 4 and SAPI 5 Text To Speech Engines:

SAPI 5 Text To Speech
ttseng5.exe English speech engine and 2 voices

Total download size varies from 9 - 12 MB

SAPI 4 is an older technology, and we recommend using SAPI 5, but SAPI 4 may have more voices available.  To use SAPI 4 first install spchapi.exe, and then msttsl.exe.
