Google Voice is a free service with useful features for people with hearing loss.
1. You can set it to ring all of your phone numbers (home, cell, work, etc.) whenever anyone calls you. This increases your chance of hearing the ring.
2. Google Voice can transcribe your voice messages and send the text to you with the original audio as well. So you can hear the message and see a transcript of it.
3. If you answer a call using a phone that’s hard to hear on, you can transfer it to any other phone you want.
