[Paid Software Announcement and Discussion] vgergo:
Future Features

Items on this list are implemented as the userbase grows. The numbers represent a tentative priority based on difficulty, importance and number of user requests. I may implement an idea from lower in the list, or postpone another infinitely.

You can motivate me with good Play Store ratings and upgrades to Pro ;) Please recommend the app.

Wildcards in the pronunciation / blacklist by phrase

option to filter out/shorten phone numbers (Number starting XY...) and URLs (xy.com "url")

100% handsfree for regular text (SMS) and email (gmail). These are the only two services left which are not locked down :(

Dial option for numbers in SMS and missed calls?

Announce notification changes (music apps - new song e.g. Spotify) They work on Lollipop devices, if not, it's not possible :(

Special treatment for time/phone numbers in notifications (time: say how much time to or since, phone: only say the first few digits) ~ already doing in some cases

Language detection based on unread part of the expanded text too

Localization (Hungarian, Polish, etc)

Show contact icons (notification icon) instead of app icon

Deeper integration with certain apps (Gmail, Messages: read all texts from the past hour, or all unread texts, or new texts from one person), reply by voice without paste etc.

Pause, rewind summary readout + Repeat!

Contextual messages: amount of time since last summary, temperature change since last readout, voice command dependent greeting

Message queuing with voice-only notifications too

Announce caller's name over bluetooth Might not ever be possible in new Android versions
