Read-along
Open the guide and choose Read this page. The spoken sentence is the block on screen. The matching menu chip glows.
The browser picks the most natural English voice it has. You can change voice, rate, and pitch. Ambient sound stays off until you turn it on.
If the microphone is missing, type instead. This lab ships no pre-recorded speech clips.
A short passage
An agent here is a loop that may call a tool. A workflow is enough when the steps never change. A voice turn still uses that cap.
Retrieval puts a passage in the call. If the passage is missing, refuse. Fluency is not a citation.
