To enable SpeechStream:
Use the SpeechStream toolbar
With SpeechStream enabled, the Activities toolbar displays a Text to speech button for Assignments and Rich-text activity types.
Pressing the button (which looks like an ear) hides and shows the SpeechStream toolbar that reads the assignment text aloud using the play button.
Depending on your configuration with Texthelp, your SpeechStream toolbar can offer additional tools (learn more).
