Voice Recall lets you practise by explaining a topic out loud. Knowie asks questions, listens to your answer and gives feedback. It is part of your exam study plans, in the app and on the website.
In the app
- Open your study plan and choose a step called Explain out loud. The first screen says Explain it to Knowie.
- Tap Start learning. If you cannot talk right now, tap I can't talk right now and continue with the rest of your plan.
- Tap Tap to answer, explain your answer, then tap Tap to send.
- Read the feedback and tap Next question.
During a session, Reveal answer shows the answer and Skip question moves past a question. At the end you see which explanations were good and which need more practice.
Voice Recall steps use energy when your account has a limited study-plan allowance. Check your remaining energy and the refill information shown before continuing.
Microphone access
The first time, the app asks for your microphone. Tap Allow microphone. If you turned it off earlier, the app shows Microphone access needed. Tap Open settings and allow the microphone for Knowunity.
On the website
Voice Recall steps also appear in your study plans on the website, shown as Explain out loud. The steps are the same as in the app: Start learning, Tap to answer, then Tap to send.
Allow microphone access when your browser asks. If you see Recording isn't supported here, open the app instead.
If the website shows Check your microphone:
- Microphone access is blocked: allow the microphone for knowunity.com in your browser's site settings. If it is still blocked, check the microphone privacy settings of your computer, then try again.
- No microphone found: connect a microphone, or check the microphone privacy settings of your computer, then try again.
Tap Back to microphone to try again.
Your recording did not send
- Send again retries sending a saved recording.
- Record again lets you replace a recording that could not be saved.
- Reload session restarts loading when the answer could not be confirmed.
