Tobi: Use multiple text-to-speech (TTS) voices to record text
Tobi provides a TTS feature which can be used to record the document text using any of the available TTS voices installed on the system.
Tobi generates audio using the synthetic voices selected in the Audio Settings. Different TTS voices can be selected to record different elements of the text. For example, you can choose a male voice to read the headings and a female voice to read the remaining text. The mapping of a TTS voice is done with different TTS elements and therefore there are many possibilities for using different voices.
To open the settings dialog, click to open Audio menu and then click AUDIO SETTINGS. The following audio settings can be modified using this dialog box:
- Playback: The output sound device (primary sound driver) used by Tobi.
- Recording: The input sound device (primary sound capture driver) used by Tobi.
- TTS: The default voice used for text-to-speech conversion.
Synthetic voice mapping: Opens a pop-up text box where you can enter the configuration mark-up for mapping the XML elements to different synthetic voices.
For example, if you wish to choose a different voice for reading headings and paragraphs, you can list the headings (h1, h2, h3, etc.) under a synthetic voice and paragraph (p) under another synthetic voice. A sample from the configuration file is given below.
[TTS_VOICE] Microsoft David Desktop
[TTS_VOICE] Microsoft Zira Desktop
- After making appropriate selections, click Close to commit the changes to Tobi and return to application window. You can cancel the changes by pressing Esc.
Now you can generate synthetic voice equivalent for the text of the document in the following ways:
- To generate audio for the entire document, click Audio->TTS audio (Entire document) on the menu or press Shift+Ctrl+G.
- To generate audio for the selected item (section, paragraph, sentence, etc.), click Audio->TTS audio (Selected text) on the menu, press Ctrl+G, or use the Generate TTS button of the Audio toolbar.
