*Talking to Machines.
==Engines==
*Google ASR wrapped for processing - http://stt.getflourish.com/
==Installing CMU Hands-on with Processing=====STT Library===*Download and install the STT library. http://dl.dropbox.com/u/974773/_keepalive/stt.zip*Download the library file, unzip it, and copy it to the ''Processing\libraries'' folder.===Example - Listening with Google ASR ===*Processing example: **http://wiki.roberttwomey.com/images/c/c2/Google_listen.zip*Try switching the recognition language. "es" vs. "en", "de", "fr". ==Hands-on with Sphinx=====Installation===
*Download from sourceforge: http://cmusphinx.sourceforge.net/wiki/download/
*If using windows, you need the '''sphinxbase-0.8-win32.zip''' and '''pocketsphinx-0.8-win32.zip''' files. I already downloaded these for you. They are in the '''untref_speech ''' folder.
==Using sphinx=Usage===
*open a terminal. Windows, Run->Cmd.
*change to the pocketsphinx directory.
**<code>cd Desktop\untref_speech\pocketsphinx-0.8-win32\bin\Release</code>
*ENGLISH: run the pocketsphinx command to recognize english:
**<code>pocketsphinx_continuous.exe -hmm ..\..\model\hmm\en_US\hub4wsj_sc_8k -dict ..\..\model\lm\en_US\cmu07a.dic -lm ..\..\model\lm\en_US\hub4.5000.DMP</code>
*SPANISH: recognize spanish:
**<code>pocketsphinx_continuous.exe -hmm ..\..\model\hmm\es_MX\hub4_spanish_itesm.cd_cont_2500 -dict ..\..\model\lm\es_MX\h4.dict -lm ..\..\model\lm\es_MX\H4.arpa.Z.DMP </code>
**this should transcribe live from the microphone.
===Language Models==='*''Acoustic models''' versus '''language models'''.*''Grammars'' versus ''Statistical Language Models''.*Available language models for Sphinx:**English**Mandarin**French**Spanish**German**Dutch**and more: http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/
===Library===
*JAR file and some necessary language and acoustic models to do Sphinx-based speech recognition.
*Download the zip file below and copy it to your Processing/libraries folder:

==Training =Example - Grammar-based Recognition ===*Simple grammar-based speech recognition with Sphinx4 in processing.**Download file: http://wiki.dxarts.washington.edu/groups/general/wiki/d7564/attachments/63c05/sphinxGrammarCustomdict.zipthis example uses a simple grammar. In the data folder it has a grammar file (.gram), a dictionary file (.dict), and a config file (.xml)the grammar file (upstairs.gram) is a JSGF format grammar file that lists the possible words your system can hear. It has a format with individual words in upper-case letters, and a "|" mark between each word. You should be able to edit this file and fill it with your own words.the dict file (upstairs.dict) is a pronunciation dictionary file. It breaks each of those upper-case words fro the grammar into phonemic units. The easiest way to make a new dictionary with your own Models==words is to use the online language tool described below.grammer finally, the config file (upstairs.config.xml) specifies various parameters and file-names for the speech recognition engine. In this file you will probably need to change the path to your data files such as the grammar, dict, and the Library files you installed above. If you edit the xml file you will see that a lot of the paths are of the form "/Users/rtwomey/" which is trivialobviously my computer, replace with the path to the file on your system.contact me if this doesn't work
==Programming with Speech Recognition=Online Tool for Training Language Models===Processing*This produces a statistical language model and dictionary (along with various other products) for the text you upload.*Your source file should be plain text, one sentence per line. *Upload the file and then click "Compile Knowledge Base. '''Sphinx4'''"*On the results screen, click on the .TAR file to download it. Unzip this file:**The .dic is your pronunciation dictionary. You may want to rename it to .dict to match the files in the java interfacesketch. Or change your config file.**The .lm file is a 3-gram SLM file. If you are trying the SLM example above you will need this as well.*The grammar example above runs from a grammar (.gram) and a dictionary (.dict). This online language tools generates the dictionary for your text but not the grammar. You will need to make the grammar on your own.*The SLM example above runs from a grammar (.gram) and a language model (.lm). This online tool generates both files.*Sphinx Knowledge Base Tool: http://www.speech.cs.cmu.edu/tools/lmtool-new.html

==VoicesHands-on With Processing==For Google TTS no library is required. You don't have to install anything. You just need an internet connection to talk to google. ===Example 1. Speech===*http://festvoxwiki.roberttwomey.orgcom/dbsimages/indexd/d2/Google_speak.htmlzip ===Example 2. Daisy Bell===*httpsDaisy Bell - http://githubwww.youtube.com/joseguerrero/festival-spanish-voiceswatch?v=41U78QP8nBk**"Daisy Bell" was composed by Harry Dacre in 1892. In 1961, the IBM 7094 became the first computer to sing, singing the song Daisy Bell. Vocals were programmed by John Kelly and Carol Lockbaum and the accompaniment was programmed by Max Mathews. *Processing Daisy Bell example using Google Text To Speech.
