Constantly-on speech recognition listening for just one keyword.
I am trying to do is making my app constantly listen for one keyword that will fire an intent whenever the keyword is recognized.
I know that this will use a lot of battery. and I don't want to use google's speech recognition.
For example - you are talking with a person. Normal conversation. The phone is actively listening and recognizing every single said word and listening for the keyword.
Let's say the keyword is "cheese" in this instance.
Whenever you say "cheese," the application fires an intent that starts up another part of the app.
I tried to record myself saying "cheese" into wav file
And then comparing it to every word that was spoken..
my problem is finding the right tool that can help me perform this signal comparison in the simplest way so it can work on any device..
tried musicg library with fingerprint function but it does not work so well..
tried some other fft/cross-corelation/ect.. functions but I didn't get the result I expected..
any help (examples or some library would be best) that you can give me will be very appreciated ..
