It is an educational mobile app for Android for kids 2-4 years old - Learn the English alphabet. The idea is when kid presses a button and speaks a letter from the alphabet - image of the letter is displayed on the screen.
The main point is the speech recognition everything else has been made. Developed with Unity.
The current speech recognition performance is poor. Streaming speech recognition is used for recognizing letter sounds BUT most of the times it doesn’t recognize the letter spoken, sometimes it shows different image, sometimes it recognizes the letter but shows image with delay.
With google cloud there was a big delay in response so it is also not acceptable and it requires user to press stop service button after voice recognition finishes. It is not easy to be used by 2-3 year old children.
The job is to improve the speech recognition performance to be excellent!
