With Android Live Transcribe you can see words appear on your Android phone as they’re spoken. You can also reply just by typing your message on the phone. It also works to show you how loud your environment is to ensure it is able to pick you up sufficiently. It also supports external microphones through headsets to allow you to speak hands free.
Android Sound Amplifier enhances audio from your Android device using headphones to provide a more natural listening experience. It helps to filter, augment and amplify the sounds in your environment, even allowing you to carry on conversations just by adjusting the sound levels to boost quiet sounds and reduce the loud noises.
