Installing Voicemail Pro: Voicemail Email

2.7 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 64 , TTS can be used to provide email reading 86 to selected mailbox users.

∙TTS can be used by the Voicemail Pro client user to record prompts

179used 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, 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.
