First, please make sure that the Mango Languages website has access/permission to use your microphone. If you are unsure how to do that, click HERE.
Look for the orange microphone icon. It will appear after the answer is shown. Click on the orange microphone icon to begin using the voice compare feature.
After you have clicked the correct icon, you can begin voice recording by clicking the large orange microphone icon in the center of the screen.
The recording will start immediately and the icon will become orange with a square in the center. The recording will last the same amount of time it takes for the native speaker to say the phrase, then will end automatically. You can rerecord your voice as many times as needed.
Once you are done recording, click, hold, and drag your voice-wave to adjust it so it aligns with the narrator's voice-wave.
Now, you can listen to each voice individually or at the same time to compare pronunciation and inflection.
