The TTS voice used by the Pipeline Lite Narrator tool to produce the audio content is the voice configured by default on the Windows environment of the user. The Pipeline TTS Narrator tool gets activated when a document is converted to full DAISY book using Save As DAISY Translator.
The user can change this voice via the Windows Control Panel:
- Go to the "Control Panel" (available via the "Start" button)
- Switch to "Classic View" (or "Category View")
- Open the "Speech" item
- Select the "Text to Speech" tab
- Select the required voice in the "Voice Selection" drop-down button
Further fine-grained configuration (such as silence duration, multiple language support, accronym pronunciation, etc) is currently not directly exposed to the end user. Advanced users can however refer to the DAISY Pipeline developer documentation to fine tune the internal configuration files located in the Pipeline Lite installation directory.
