I have a couple of wall mounted tablets (Samsung Galaxy Tab 3), which i use to display my security cameras. I now started using them for voice control. I am using autovoice in combination with tasker, Authomation and AutoVera. Autovoice is set to always listen. Battery is not an issue, as the tablet is connected to a charger. Voice control works really well when i am close to the tablet. But the tablet is about 3m or 9ft away from where i am sitting. Even when i shout it does not pick up the commands. So i thought of using a external microphone. The ideal solution would be a wireless microphone which i can put on my coffee table in front of me. There is no power or possibility to run a cable. I was thinking of using a bluetooth microphone. Is that possible (I want it always on).
Has anybody done something like that, any suggestions of what i could use ?
I’m in the planning process of organizing tablets for the new home I am building, and plan to use them as switches and like you, for voice control.
I wonder if there might be an app that can be downloaded and can adjust the sensitivity of the mic? I’m also thinking that how sensitive the mic is, is at least dependent on the device, my old HTC One’s mic was way now sensitive to my HTC One M8

Yes that would be useful. Even with the external microphones i have been experimenting with, sensitivity is not great. It works up to about 2m or 6ft distance when you raise your voice. Any further, even with shouting, it does not always pick up, or it gets the commands wrong. So it works, but it could be improved… increasing microphone sensitivity if possible would probably make it better. If you find anything please let me know…
Mike, speech recognition works best on a phone mike(s).
The reason is not the quality of the mike, but the signal processing that is used to detect and cancel noise. This is done with multiple mikes that are close to the signal source. Near field sound sources.
When you are far away the signal processing is very difficult to differentiate source signal from noise signal. As the noise component goes up, speech recognition goes down quickly.
When far away, multiple mikes that track the user still pick up all the notice that is coming from the same direction as the user. They differentiate based on direction, but still can’t tell the difference from noise in the direction of the user.
Have a look at this : http://forum.micasaverde.com/index.php?topic=23123.0 it might be a better option…
I’ve also noticed that my Bluetooth headset in my car picks up voice much better than my phone, so maybe a couple of them through the home could work…
