What This Does
Rather than typing an equation, you can say it. Helperbird listens and writes the maths into the editor for you.
Who is This For?
This is helpful for:
- Anyone who finds typing slow or painful
- People who know how to say an equation but not how to write it
- Students working with their hands full, or away from a keyboard
- Anyone who cannot remember the LaTeX for what they want
How to Do It
Click Voice typing in the toolbar. It is the microphone.

Your browser will ask for permission to use the microphone the first time. Say your equation out loud, then click the button again to stop.
Dictation also stops after ten seconds without recognized speech. The microphone closes and your equation stays in place. Click the microphone button again when you are ready to continue.
What the Messages Mean
You will see the editor move through a few states:
- Connecting while it gets ready
- Listening when it is waiting for you to speak
- Hearing while it is picking up your voice
If it never gets past Connecting, check that your browser has microphone permission for this page.
If It Mishears You
Maths dictation is harder than ordinary dictation, because so much depends on grouping. Say the structure out loud as you would to a person: "one over two" rather than "half", and "x squared plus three" rather than trailing off.
Anything that comes out wrong can be fixed by typing, or with the maths keyboard. You can also dictate ordinary text elsewhere in Helperbird with speech to text.
