Google has announced two new Android applications designed to make life easier for deaf and hard-of-hearing people. One of the apps, Live Transcribe, turns live speech into real-time captions by using a phone's microphone; the other, Sound Amplifier, improves a phone's sound output. Live Transcribe, which works on Android 5.0 Lollipop and up, will be available in 70 languages and dialects. It has a type-back keyboard for users who can't or don't want to speak, and works with external microphones to improve transcription accuracy.
