at the moment I work at a projekt to differ sounds. The sounds differ in amplitude and spectrum. In my opinion speech regonitation could be a solution.
So offline sound regonition offline on an microcontroller is not a big thing.
The only other solution I have found is a system from spansion/cypress (http://www.cypress.com/file/252901/download) and other voice regonition chips.
For example the spansion system offers voice regonition and not sound regonition. So in this system you could write a textfile with word and the system can detect this words.
But this is not a system for me because I want to detect sounds.
So I was realy happy at the moment I found this LPC54114 Audio and Voice Recognition Kit (First video). A system who could detect the door bell. Very similar to my system who should differ for example knoking hard/soft on a table.
So what is my problem?
My Problem is that I have not enough information about the Voice Recognition Kit.
- Is the system "open" so I could feed them with my sound files? And build my own reconition system?
If this is possible:
- How many sounds the system can differ
- What is the sensory libary
- Is the kit only a demonstration kit? And develop a reconition system is only possible with sensory (www.sensory.com).
Please help me before I buy this kit, try it out and recognize that the system is not "open" or could only differ 5 sounds or something else.
I hope you could understand my question.
Thank you everybody for your help,
