cbtgeek: I think audio or sound Fingerprinting will only work when you are matching exactly the same sound / audio file. 1 Like |

nollyj:Yes and no bro voice recognition can only recognize a as a b as b c as c and etc not a particular voice Now what sound finger printing does when it hash the value of highest frequency making it possible that voice with same pronunciation can have different fingerprinting Now you can find a long speech of pmb and slice off some of his regular words like nigeria,corruption,youth,boko haram etc and finger print this words if you are given a audio file ,then u match it against ur hashed words . Like every ten seconds of file against ur hashed words if it match it will return 0 else 1 With this method u accuracy is about 97% 1 Like |

cbtgeek: It is easier said. Run a simple example of sound fingerprinting with audio file record under different situation but with same voice and show me if the result is 97% match. Understand that sound fingerprinting is almost the same like fingerprinting. In sound/audio, there are many factors that differentiate two different songs from the same person. Fingerprinting works when there is a matching pattern in frame windows of two different audio files. |

At least I have learnt something new - that you can actually take the fingerprint of Sai Baba's voice. . .and make a record label of it |

You mean the money bah? It is safely locked up on nairaland's server and only the oga at the top has access - others can only try. There is no need to weep I assure you, maybe out of pity - Seun go just dash you the money. I don search web tire maybe I can find anything opensource, but no way.

I know that am not perfect but lets wait and see who can win this without finger printing Hashing,fft,wave length,amplitude,frequency, are all your friend in the contest if some body can create a voice recognition that can detect if a bird is a male or female now tell me if fingerprinting is not the answer |

Yesterday I decided to try my hand on this project. knowing that I am a beginner programmer, I am more interested on what I will learn. I did some research and read some few papers on this topic. I decided to make a rough trial demo of 3rd Party Libraries I found. My intended language was Java. I first wrote a desktop application using a Java library called Recognito. The link is here if you want to read more about the library. I will say that it is a good java library for Text Independent Speaker Recognition in Java. I integrated it to my application and checked the usefulness The NetBean Java application is attached below. I obtained the following results in four different Buhari speeches ![]() The first two results show the positive matching result of different audio speeches from President Buhari. The third result was 100 % positive when you match the same audio speeches from Buhari. Finally, the fourth result is a false negative result. When I dig into to find out why the result return negative, I realize the following factors can prevent detection of a speaker voice. 1. The encoding software used to convert from any file type to .wav file 2. Noise in an audio file 3. Quality of the audio file It is also important to understand that there is a difference between Speaker Recognition and Speech Recognition. According to wikipedia - “Speaker recognition is the identification of a person from characteristics of voices (voice biometrics). It is also called voice recognition. There is a difference between speaker recognition (recognizing who is speaking) and speech recognition (recognizing what is being said).” I went on to test Audio /Sound Fingerprinting in android app (The file size is big to attach here. I will look for a way to share to anyone that wants to download) 3 Likes

Java Sound Fingerprinting Library After I finished the demo for Desktop, I decided to port a new application to android mobile since I like developing for android. I decided to try sound / audio fingerprinting java library called Musicg. The link is here if you will like to read more. https://code.google.com/p/musicg/ Th android application has the option to add audio file in three different ways. The display of the app is as shown below. ![]() You can download the source code for the android application. Sound / audio fingerprinting result from android app I was able to achieve 100 % positive match using fingerprinting for the same audio file. With other different audio file with same speaker returned no match. 6 Likes |

In reality, this is a difficult area with the level of my programming skill. There is also the possible to obtain better result with other programming language that I did not test. No doubt I have learn something new. Time to go back where I belong (Android Development). 2 Likes |

Seun, will possible Buhari source file(s) come from radio, television (press conference), phone, or live mic recordings? Or are all sound filters and fidelities possible? I need a break from 3d printing and web crap ![]() |

Let me explain once and for all the kind of buhari your app must capture: - Buhari's voice when he was a baby (crying) - Buhari when he was a teenager - Buhari before He became president - Buhari when he had a cough and sorethroat - Buhari if he is speaking with his mouth full (but he shouldn't anyway) And it must be able to detect it was buhari: - when he speaks in a party with jamz rocking - when his voice is broadcasted from a megaphone across the street - when his recorded voice is being played with my nokia 3310 - my daddy's record discs Under the following moods: - happy - sad Under the following moods: - crying - singing In the following dimensions: - Mono - Stereo - 3D surround In the following weather conditions: - Heavy rain with winds blowing - Thunderstorm situations Well. . . . .if your code can fulfill all that, I see no reason why you should not win the award - Happy coding 6 Likes |

dhtml18:I've already started pulling down rouge libraries without having these pertinent cases addressed. Youtube uses an automated approach when policing for copyright music samples in uploaded videos. There are ingenious ways around Youtube's sniffer which requires changing the music samples and/or video fidelity (youtube doesnt send minions listening to every upload for possible copyright violations and it doesnt solely count on youtube users flagging violations). But with this project we dont have the slightest idea of what type of Buhari voice to expect, to further promise to deliver 90% accuracy of an unknown. Somehow I started coding..

dhtml18: I dont need the money... but a different puzzle is always nice. I'm having other computational issues from other projects at this moment that I'm pushing off. I'm glad to procrastinate on this (if Seun ever comes back to answer questions)... and I like see other programmer's approaches, questions, and bemoanings as well, this is good homework. |

In artificial intelligence there must be a predefined training set. Biometrics is affected by age, hence your voice, gait etc doesn't stay the same. In this case the buhari voice should be from current speeches. I would have attempted this assuming the code isn't open else let's see some real cash 1 Like |

I really don't think Seun would search for a recording of Buhari when he had soar throat or when he was crying. From the first post, it's pretty obvious almost all your stated conditions would not be required. dhtml18: |
