HailSpeaker is a virtual megaphone software running on a mobile device. Connect a Bluetooth speaker to your device and start projecting your voice!
To use HailSpeaker, click on the big red button. When it turns green you can speak and your voice can be projected to the Bluetooth speaker. When you want to stop projecting to the speaker, click on the button to toggle it back to red.
Your projected speech will also be transcribed at the same time. Click on the text document button at the bottom bar to view the transcription. You can also export your transcription.
