So this idea is from a Sanyo flip phone I had way back in the day on Sprint. Granted, it's not the most useful thing in the world, but it would be nice for times when you want to know why someone is calling before you answer the phone.
There was an option where after 4 rings the phone would answer play a locally stored greeting, then record a message locally. Now, the helpful part to me was the fact that (unless I hit a button to mute it) it would play the outgoing and incoming messages where I could hear them. Being this was several years ago, it couldn't play it over Bluetooth, which with better technology on both the device and headset ends, that would be possible. (My Motorola Elite Flip, for example)
But I'd like to see it go a step further, and make this a full featured answering / auto response system.
Say you're driving, and someone calls you, you hear the message they're leaving via your hands-free (either in car or headset) and decide you need to take the call. Instead of pressing a button, just say "Answer it". Or say "Ignore it" and the answering system would mute, the phone audio would return to whatever you had on previously, be it music or sat nav.
Similarly, if someone sends you a text, you could have it read to you on TTS, then the app would ask "Would you like to reply?" You could say "No" and the app would send a canned message ("I'm driving. I'll get back to you soon." or something similar), or say "Yes" then dictate your message by speech recognition.
With this, an auto filter would also be handy. Numbers not in your phone book, or numbers you set as black list, are automatically sent to the screener, while other contacts are not.
I think greetings should also get some options as well, like the option to have different greetings for different callers, or different caller groups, and the option to either record your greeting, or write one to be played to callers by TTS.
I've seen apps that do bits and pieces of this idea, but nothing that consolidates them, and the apps I've tried don't work very well, and they don't have the right feel. This app should be something that would feel like it was included stock on Android. Clean, simple, and intuitive.
Anyone interested in a project?
Apologies for any typos. I can't find my reading glasses.
