I am developing a system which includes a speech comparison. This system will be used by people having a speech disorder. Practically I need to capture the user's speech and compare it with a another speech audio file and return a percentage match. I need to develop this in Java.
I started doing some research and found that this can be done using some sort of algorithm using FFT.
Is there any other algorithms which you may suggest in order to implement this comparison of capturing the user voice and comparing it with a pre recorded audio file and perform a real time audio processing.
I need some assistance from you guys in which is the best way to handle this and develop it with the best practice.
Many thanks for your time! Much appreciated

Basically, this blog post shows an implementation of the FFT algorithm using Java.

Data recovery on android
I'm interested in learning how data recovery tools are typically implemented. I've searched online and have not been able to find much information on this topic, so I'm looking for someone who can provide an overview of how these applications work. Specifically, I would like to know what techniques and algorithms are commonly used to recover lost or deleted files from storage devices. Additionally, if you could recommend any resources or references for learning more about this topic or for implementing my own data recovery application, that would be very helpful. Thank you!
I am expecting that someone give me a clear insights on how this works.

I want to create a reddit 'novelty' account bot to better my coding/scripting skills. Currently I just want to make a simple bot that searches new or rising links on reddit and looks at the comments in each thread. If the text matches some string of characters, the bot replies with a message.
I know this is a really general question, but I'm looking for tips on which scripting/programming language to use. I mainly have experience with Java and Selenium along with R and a little bit of batch. I am willing to learn a new language (i have a lot of free time). Also the goal of the bot isn't very difficult, so even if i had to learn a new language I don't think it would be all too difficult.
Most reddit bots are made with something called PRAW. You use Python when creating something with PRAW. Python shouldn't be too hard to learn if you know Java.

I want to improve a JAVA program performances using GPU programming.
After some research on the internet I found that it is possible if i use jcuda or jocl, but the problem is that the kernel code must be written in C in both cases.
and the algorithm that i want every thread to execute is very complicated to be written in C (it does some computations to know if there will be an accident between two aircrafts) so an object-oriented language is necessery.
Is there a solution ? or must we translate the whole project to C++ ?
Thanks for your help !
Simple rule: if it needs object orientation, it looses its performance. Even if you are using GPU acceleration.
I would advise you to identify the parallel parts of your program code. You do not have to transfer all of your algorithm to the GPU device. Is there any aspect of paralellization, e.g. arrays or grids that are filled?
What kind is your simulation message exchange? Is it explicit, i.e. sending messages around your kernels, or implicit via synchronization.
You should at least give us some more information about you algorithm and its data layout.

I need to design a testing system which would not allow to use google. I mean that, theoretically, the user still can do it, but the purpose is to hinder this as much as possible.
I have an idea, but I don't know how good it is. I want the question in the database to be a simple text. And when we need to load it to the test, we convert it into a picture with a watermark. But the problem is that, theoretically, it still can be recognized. Google is able to convert the text on the image into the text and then search it as a text. Google is also able to recognize images despite some hue differences on them. Does anybody have proposals on that score? What would you do?
just use robots exclusion headers on the page to tell google not to store your page. or even robots.txt
As you say if it's human-readable, google will read it. Google has millions of slaves doing OCR for them (via Re-Captcha). but if you tell google to leave your site alone, it will.

Does anyone know of a way that I can either code a program (preferably in java), or use an existing program or API that will listen to the microphone and convert what you are saying into text and save to a file? I do not want it to have any fancy features, I just want to have a lightweight speech to text program that will use very little resources so that is will be fast and simple.
Thanks in advance for any help! ☻
Nilpmet,
I must have done this at least a dozen times using CMU's Sphinx, their continuous-speech, speaker-independent recognition system. Sphinx has a Java API which is pretty great.
Please let me know if you have any questions!
You can use Google's speech API, demonstrate here.
Here is a reverse engineering of this API, you can get your speech API key here.
