SHORT EXPLANATION
I'd like to create application for mobile phone and server such that:
1. User runs application on mobile phone with Android, this application uses PocketSphinx. It is Automatic Speech Recognition software for devices like mobile phones, written in C. Somebody told me that "Pocketsphinx is used successfully on Symbian with minimal effort". (However I think Android may be better choice). My knowledge about Android is limited but I know something about CMU Sphinx. Can you help me, please, to run this PocketSphinx on Android? I also need to find simulator of mobile phone with Android. I have already found Wireless Toolkit and I tried to use this emulator, however I think it doesn't allow to run simulation of mobile phones with Android. (By the way I am limited in my project to mobile phone of the price up to about 160 euro; which Android version would be best for my application?).
2. This application communicates with the user. The users speaks digits and some other words (dictionary is about fifteen words, I can create language and acoustic models, as well as formal grammar in CMU Sphinx, with the use of SphinxTrain). The application recognizes those digits.
3. Based on this talk, mobile phone sends information about results of recognition to the server. I can do it in Java for CLDC/MIDP with httpconnection, POST method on the mobile phone side and with Tomcat on server. I think this httpconnection must be possible not only in Java ME, but also in Android C. But this is thing which will bother me later, now I'd like to run pocketsphinx_continuous on Android and try to modify it according to my needs.
Summing up, what I'd like to know is how to run demo pocketsphinx_continuous on mobile phone with Android, and how to do it with simulator of mobile phone with Android. (I've got Wireless Toolkit but I think it is not capable of running Android). PocketSphinx can be downloaded for free here, for both Linux and Windows: http://cmusphinx.sourceforge.net/html/download.php . There are two ways of installing it in Ubuntu. First is to unpack it (it is tar.gz), enter its directory and type "./configure", "make", "sudo make install". The other, different, is written in README file, i.e. run autogen.sh, "./configure", "make clean all", "make test", "make install". The result should be, among many other files, javadoc in doc directory.

LONG EXPLANATION
What is required to give me some advices is written above. So if you don't want / don't have time to read the whole text, just above explanation is enough. But let me say about other possible approaches which I try to do. Those are worse than what I explained above, but I also tried them.
CMU Sphinx contains SphinxTrain to create acoustic model. It has got some different recognizers (also called decoders), those are PocketSphinx, Sphinx4 and some other. PocketSphinx is written in C and is for devices like mobile phones. Sphinx4 is Java application for PCs because it requires better hardware. There is good tutorial about using SphinxTrain with Sphinx4. It is here: http://www.speech.cs.cmu.edu/sphinx/tutorial.html . There is no similar tutorial for PocketSphinx. However with some knowledge about Android and C it is possible to run it on Android. The other approach than PocketSphinx, is using this Sphinx4. However it requires connection between mobile phone and server, sending audio data from cellular phone to server. It can be done with Skype, but there is still problem on server side with redirecting sound from Skype to Sphinx4. So you see there are two different approaches. One is to run speech recognition on mobile phone with PocketSphinx and Android. The other is speech recognition on server with Sphinx4. There are some ways to follow this second option. One is Skype on both server and mobile phone. (But there is problem with redirecting speech from Skype to Sphinx4). The other is too expensive Digium card. The third one is IVR, but I still look for good open-source IVR software. All of those three ways of second option involve Sphinx4. It was much easier to create application with Sphinx4. It is for PCs, not embedded devices, because it requires better device, extensive floating point math and some other things. But it has much better documentation than PocketSphinx. But I want to use PocketSphinx because I don't need to pay to anybody for access to mobile internet in order to send data through internet for application like Skype. The access to internet is required only for short time to send little text data with httpconnection, POST method. This is why I'd like you to help me, please, with running pocketsphinx_continuous on simulator of PocketSphinx on mobile phone with Android. (By the way, I see I've got installed S60 Developer Tools -> 3rd Edition FP1 SDK -> MIDP -> Emulator).
Summing up in a list, those are in CMU Sphinx:
I. SphinxTrain, which I can use to create files needed for speech recognition
II. decoders which use speech input and some files which I create with SphinxTrain, to follow speech recognition (input speech + files from SphinxTrain = are used by decoder)
II-1. PocketSphinx, written in C, for devices like mobile phones
II-2. Sphinx3, written in C, for PCs, actually the best developed
II-3. Sphinx4, written in Java, for PCs, with the best documentation
II-4. Some other, older versions
Those are possible approaches of solving my task:
I. Speech recognition on mobile phone with PocketSphinx. This is much better way than [II].
Problems: 1. running PocketSphinx on mobile phone with Android. 2. simulating mobile phone with Android on PC. I also thought that maybe I should consider Meamo, what do you think about it? Or use things different than CMU Sphinx, e.g. Simon, HTK, Julius. I looked at those other ASR engines and I think PocketSphinx may be best choice.
II. Speech recognition on server with Sphinx4. There are some different ways of establishing voice connection between mobile phone and server.
II-1. ordinary call from mobile phone to server; server has got Digium card. Disadvantage: Digium card is expensive.
II-2. to use Skype on both mobile phone and server. Problem: redirecting of sound from Skype to Sphinx4 and vice versa.
II-3. can you think about any other ways? I found that Asterisk may be useful.

First step would be to setup a toolchain and compile the prog for android
or statically linked with uClibc.
Then push it onto your device and test if it works as expected.
You can also push it onto the android emulator that comes with the sdk.
Just my 2 cents...
Thank you very much!
Can you give me any links to tutorials which can be useful for me?
By the way I know how to create my own application in Sphinx4 and I know how to run demo in PocketSphinx, but I've got some difficulties with creating my own application for PocketSphinx. So if you can have a look at PocketSphinx http://cmusphinx.sourceforge.net/html/download.php and tell me which files I need to have to create new project for PocketSphinx, I would be greatful. I mean that for Sphinx4 the only what I need to do is to enter S:\tutorial\sphinx4-1.0beta3-src\src\apps\edu\cmu\sphinx\demo\helloworld and create my own ...\demo\my_application, and inside it analogically to what is here ...\demo\helloworld. In the case of PocketSphinx, to run the application, I need to enter S:\tutorial\pocketsphinx\doc and run pocketsphinx_continuous. So I check what I've got in this file and I cannot see what files and where I need to have in order to create new project. I uploaded directory doc with pocketsphinx_continuous here: http://www.speedyshare.com/files/19429494/doc.7z
Greetings and thanks once more !
Rough outline: You'll need the Android SDK and NDK, both of which are available from http://developer.android.com/. The NDK will allow you to compile C code. You'll need to wrap the C core in a Java layer to make it accessible to the rest of the Android system. The SDK also includes an emulator, which I believe you've asked for if I understand you right.
I haven't actually attempted this, so that's about all the help I can be, but there is sample code included with the NDK that should get you started.
Thanks for your answer !
I check the google and see that NDK is term of Android, because I knew only SDK abbreviation. I assume NDK is especially for porting (like porting PocketSphinx for Android). So am I right that with this NDK I don't need to change code of PocketSphinx? I think it would be too easy .
There also other question which I've got. It is not strictly connected with Symbian but there wouldn't be any need for porting if I won't solve this problem. I've got my application in Sphinx4. There are also examplary appications for Sphinx4 and PocketSphinx. I can run demos from PocketSphinx (as explained in first post), as well as demos from Sphinx4. I can change source code of demos from Sphinx4 to perform my task. I'd like to do similar thing with PocketSphinx, but even if it should be easy task, I cannot do it. In Sphinx4 it is much simpler because all source files are in one directory. In PocketSphinx it is done in somehow different way. (http://cmusphinx.sourceforge.net/html/download.php). Without ability to move my application from Sphinx4 there is no need for me to port this PocketSphinx to Symbian.

NDK is used to write software for Android devices that are compiled natively to the platform -- for now, this usually means ARM. Java as you probably realize is a bytecode intermediate language that the java virtual machine converts to native calls at runtime. This means that Java is generally platform independent whereas your C code is not.
JNI as used with the NDK is the Java Native Interface (or something to that effect). It allows you to call code that has been compiled for a specific processor from Java. This means that you could put heavily optimized super fast calculations in a native library and call them from your Java app.
It could also mean, that you've more or less written your entire application in some native code, and then you have written a java shim that has enough code to initiate and start your native software. Beware, there be dragons here.
The fact that you CAN do this, doesn't mean you SHOULD. There are a lot of benefits to using the android platform and specifically using the android way of writing applications. Concepts like views, activities, intents, etc., greatly simplify how an Android device interacts with other Android devices and provides a consistent and powerful framework.
For something like SCUMMVM, it is a game (platform) that is very linear in design; you are either actively playing it, or it is on pause. How other applications are running while using SCUMMVM is inconsequential. It sounds like you have very different requirements.
Thanks for answer!
Isn't that link (http://cmusphinx.svn.sourceforge.net/viewvc/cmusphinx?view=rev&revision=9470) simply trying to copy engine library to Symbian, without effect? Only enginge won't help, there is also need to write from zero code which will use this library. So it looks like there is still long way to have it working. Do I understand it properly?
Greetings!
People,
I don't know about you guys, but as an engineering student I use a lot Latex to produce documents (articles, presentation, reports, etc...). However seems that a good app to latex edition is lacking in the android world. The hard time to deal with a latex document is having a high number of files and sub-files, and need to be compiled in order to get the final result, a pdf ou dvi file.
Testing alternatives, I found that the compile part is easy, since, as done in the iOS, the best alternative to the 1GB program needed is a remote compilation in a server. Some schools have it, some web applications already use it, and even verbetex (the only LaTex app, besides its limitations) use this approach. For instance I leave you a great project, but a little bit stoped this days..
http://dev.latexlab.org/
The main limitations all the apps and web-service present is file manipulation and text editing. Neither can be good in both, wich is essential. The project I showed could be great if, besides google doc integration (allowing cooperation), I could easily manage the file as its possible in http://www.scribtex.com/. However, the best integration in file manager would be using dropbox, where easily one can add files from desktop, or web browser, editing in normal Latex tools, or in the fly in our tablet or webservice.
Besides a webservice seams a good alternative in desktop, android browser is still not so easy to use. So a dedicated interface, wich allows multiples tabs, to edit multiple files, syntax highlighting, files manipulation with integration and sincronization with dropbox, and some other text edition addons with the possible to online compilation in a remote server would be a very nice app for our android, and mostly for TF since it have a dock.
I don't have for now programming knowledge to promote this type of project. Figuring current available apps using dropbox, remote servers, and text manipulation, I assume necessary tools are available, so I let year a challenge to the brilliant guys in XDA, offering me to test, and when finished to buy it (if it would be a generic code editor for differente languages, allow dropbox and ftp integration, for sure that 10 bucks or more would be a good price for start).
Hope some one respond to my call!
I can think of another use for Latex..........
SORRY! HAD TO SAY IT!!!
I also happen to be a student who regularly use LaTeX for academic purposes. In my opinion, the best solution that exists now on the Transformer is using Vim for editing the tex files, and using sftp to upload it to a server and then ssh to compile it. The later parts can be put into one shell script, and can be executed within vim each time you want to compile the file that you are editing.
As to the editor itself, vim is exactly what I use on my regular laptop for LaTeX editing. I can hardly think of any editor better suited for the job (though some might suggest emacs, but that is another story). Someone has compiled vim for android and you can find it by googling "vim android". I have tried it myself and found it quite usable with the dock. You can even use the excellent vim-latex plugin to help you simplify the editing of latex files.
Vim is too hardcore for me I have it already setup, but not all latex guys like to do it in the terminal
I'd like to share a very easy way to rapidly create reasonably sophisticated android phone apps using a simple technique I've been working on. The short version: I'm importing complete HTML websites into an open source android IDE and compiling them into .apk's. The resulting apps look good and perform well.
Here's the basic technique:
1: Download and install the free MoSync SDK.
2:Open up your HTML editor and create a multipage website, scaled to phone screen dimensions. Feel free to include phone numbers, links and so on. compile and save it somewhere.
3: Go to the MoSync project folder you're working with, and replace the contents of the "LocalFiles" folder with the copied contents of your compiled website. Be sure to copy all the folders and files from your site over. Once you have done this, either reopen or refresh the conents of the folder in MoSync.
4. Connect your phone ( you can also run in emulation ) and locate it within MoSync, then compile and send the app over. It will install and launch.
... that's really about it. The only thing I've seen so far is that the over apk size can't be larger than 5MB's or so without the phone refusing to launch the app. Your mileage may vary, but this technique is great for folks like me that have solid HTML experience but are somewhat new to Android development and would like to create something simple but functional while they aquire the new Android skills. Hope this was helpful!
Hi, I'm a final year Computer Science Student. My Final year project is to design a windows phone 7 app for transferring files from a remote database /sever to the windows phone device.
I have never been taught any C# or windows phone development. So far I have developed a windows phone 7 client app which connects to an SQL Server 2008 database, I can query the database from the app and return and display the text stored within the database tables. I am also able to store a picture in the database as binary data.
Can anyone advise me is it possible to store pdf and office documents within the SQL server database and download them to the windows phone 7 client and then open/view these files on the device. I believe that any files must be downloaded directly to isolated storage on the device but that there are restraints where that these files cannot be accessed by any other apps on the phone.
Any help or advice would be greatly appreciated..
It's possible to open supported media and documents (pictures, PDFs, etc.) from an app, I'm pretty sure (for example, see the SkyDrive app). I know that it's possible using native code and a couple of other mildly undocumented features. Using only official APIs... never tried, but I think it can be done (I'm just not sure how).
Unless you use the undocumented ID_CAP_FILEVIEWER capability in your app (or use one of a number of available hacks), your app will not have write permissions anywhere except in its isolated storage. Officially, one app can't access the isolated storage of another app, although the Office stuff may bend the rules somewhat.
This could be very good. I didn't read too much though.
AutoSploit is slightly more sophisticated but only because it leverages two popular, well-supported security tools. "As the name might suggest," its author wrote on the tool's GitHub page, "AutoSploit attempts to automate the exploitation of remote hosts." To do that, the Python script uses command line interfaces and text files to extract data from the Shodan database, which is a search engine that taps into scan data on millions of Internet-connected systems. AutoSploit then runs shell commands to execute the Metasploit penetration testing framework.
