Windows Server Installation: Voicemail Email
2.6 Text to Speech (TTS) Installation
The Voicemail Pro server is able to use Text to Speech (TTS) in the following ways:
· Speak text in call flows using the Speak Text action. The text can include variables passed from other actions
including database actions.
· When installed in parallel with Voicemail Email , TTS can be used to provide email reading to selected
mailbox users.
· TTS can be used by the Voicemail Pro client user to record prompts used by call flow actions.
TTS Licensing
Voicemail Pro TTS requires the server PC to have a Microsoft SAPI 5 compatible TTS engine installed and a valid license
entry.
· Email Reading
This feature is supported by the Voicemail Pro server's standard Preferred Edition license. Users who want to use
this feature must have their user profile configured as either Mobile User or Power User using Mobile User
Profile or Power User Profile licenses.
· Speak Text Actions / Prompt Recording
The license for this operation depend on whether you will be using the Avaya supplied ScanSoft TTS speech engines
or a 3rd party generic TTS speech engines (including the TTS speech engines included in Microsoft operating
systems).
· Generic TTS
The use of up to 8 simultaneous generic TTS ports is enabled by the Advanced Edition license. Alternatively
separate VMPro TTS (Generic) licenses can be added.
· Avaya ScanSoft TTS
The use of the Avaya supplied ScanSoft TTS engines is licensed by the addition of VMPro TTS (ScanSoft)
licenses to the IP Office configuration.
If both generic TTS and ScanSoft TTS licenses are added, both TTS engines will be used for calls on a first-come first-
served basis. The TTS engine used for particular calls cannot be controlled. Therefore we recommend that only one type of
TTS engine is licensed within a system.
Languages
For Voicemail Pro 5.0 and higher, the supplied ScanSoft TTS software now supports the same set of languages as
Voicemail Pro speech prompts except for Hungarian. If more than one TTS language is installed, a Select System
Prompt Language action can then be used to switch TTS to a different language from the selected default.
· Installation on Windows Server Operating Systems
On many Windows server PC's, while the Windows Audio components are present by default they are not always
enabled. If this is the case the playback of voice prompts may be 'choppy' and the TTS (if installed) will not work.
However, enabling Windows Audio does not require the server PC to have a sound card installed.
1. Ensure that you have full administrator rights for the PC. This process will also require the PC to be restated.
2. In the Windows Control Panel select Sounds and Audio Devices.
3. If Windows Audio has not been enabled, select the Enable Windows Audio check-box.
