Text To Speech

The voicemail service can use text-to-speech (TTS) for several functions:

  • Automatically provide an entry prompt for actions using the action’s description text.

  • Add spoken prompt’s during a call flow using Speak Text actions.

  • Perform email reading.

The speech engines used for TTS are provided as follows:

  • Locally installed – Using services installed on the same server as the voicemail service.

  • Google speech – System using subscription mode can be configured to use Google speech services to provide TTS. This overrides any local TSS service.

    • The Google speech service also provides the voicemail service with support for a number of automatic speech recognition features.
