Hello :-)! I'd like to create application for mobile phone such that: 1. user enters this application, 2. user speaks ten digits, then says stop, application checks control sum, if the sum is correct it asks the user for some additional informations, if not it asks whether the user accepts improper control sum or wants to repeat digits 3. based on this talk, application creates little text file and sends it to server (probably with Tomcat) The other possible approach (however that first one is better) is somehow different: 1. user calls special number, it connects him to server with Asterisk 2. the same as above 3. the only one difference is that there is no need to send it, it is just saved on the server. At first I thought about CMU Sphinx, i.e. PocketSphinx (C language) for first approach or Sphinx4 (Java) for second one. However now I think that it may be better idea to check other freeware, open-source systems like HTK or Julius. Which of these three (Sphinx, HTK, Julius) is better for first, and which for the second approach and why? (I cannot buy super-expensive mobile phone so hardware resources on phone are limited). [b]Can you give me, please, some tutorials which say about[/b] (beginning from most important): 1. where to download the system, how to compile, install and run it on computer 2. how to create algorithm of recognition (as explained in second point above) 3. how to run it on mobile phone! 4. how to create my own model (what kind of models? acoustic and language I guess?). I need to create my own because I need other language that English and I am sure there won't be already existing, available for free model for my language. However, maybe English model would be good enough, even if there may be some differences in phonemes. 5. suggest which mobile phone / smartphone would be best choice (maximum price 150 british pounds) Thank you very much for your help in advance :-)! Greetings :-)!
