| + | |} |
| | | |
− | == Setting up Speech Recognition == | + | ==Speech recognition== |
| | | |
− | Setting up speech recognition is done in two parts. The first part involves training of the speech data and creation of the acoustic model and the second involves the actual execution of the speech recognition engine with the created acoustic model.
| + | Robotino has already been trained for a voice but this may not work for everyone. In case it doesn't, then a new acoustic model will have to be created for that person. There are two ways to do this |
| + | #'''Recommended''' The acoustic model is created by us and we just need your training data -> [[Recording data for speech recognition training]] |
| + | #[[Creating the acoustic model yourself]] |
| | | |
− | === Creating an Acoustic Model === | + | ==Setup audio devices== |
− | | + | When the Logitech ClearChat headset is plugged into Robotino's USB port, the udev rule ''"/etc/udev/rules.d/99-robotinosr.rules"'' matches |
− | The HTK toolkit (version 3.4) shall be used to create an acoustic model. Please follow the following steps.
| + | <pre>SUBSYSTEMS=="usb", KERNEL=="hiddev[0-9]*", SYSFS{idVendor}=="046d", SYSFS{idProduct}=="0a12", RUN+="/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start", SYMLINK+="headset" |
− | | |
− | ==== Step 1 ====
| |
− | You will need to [http://htk.eng.cam.ac.uk/register.shtml register] with HTK before you can download it. Please do so.
| |
− | ==== Step 2 ====
| |
− | Download the sources for HTK toolkit 3.4 from [http://htk.eng.cam.ac.uk/ftp/software/HTK-3.4.tar.gz here].
| |
− | Also download the HTK samples from [http://htk.eng.cam.ac.uk/ftp/software/HTK-samples-3.4.tar.gz here].
| |
− | ==== Step 3 ====
| |
− | * Move to your home directory
| |
− | <pre> cd ~ </pre>
| |
− | * Create a directory called 'bin'
| |
− | <pre> mkdir bin </pre>
| |
− | * Unpack the downloaded HTK toolkit sources and HTK samples in a folder called 'htk-3.4' in the 'bin' directory. The 'bin' directory should contain the following
| |
− | <pre>
| |
− | htk-3.4 samples
| |
− | </pre>
| |
− | | |
− | *Move the 'samples' folder to the 'htk-3.4' folder as follows
| |
− | <pre>
| |
− | cd bin
| |
− | mv samples htk-3.4
| |
− | </pre>
| |
− | | |
− | * If you have a newer version of the gcc compiler (version 4 or above), you will need to install gcc version 3.4 so that HTK will compile properly. Use the following gcc's version command to see which version is installed on your system
| |
− | <pre>gcc -v</pre>
| |
− | | |
− | * If your gcc version is 4 and above, follow the listed commands to install gcc 3.4
| |
− | <pre>
| |
− | sudo apt-get install gcc-3.4
| |
− | sudo rm /usr/bin/gcc
| |
− | sudo ln -s /usr/bin/gcc-3.4 /usr/bin/gcc
| |
− | </pre>
| |
− | | |
− | '''NOTE''' - if the above doesn't work for you then maybe the hardy ubuntu package repository is not in your sources.list file. In that case, do the following. If it does work, then skip to the next bullet point. | |
− | <pre>
| |
− | sudo gedit /etc/apt/sources.list
| |
− | </pre>
| |
− | :add the following line to the end of the sources.list file
| |
− | <pre>
| |
− | deb http://de.archive.ubuntu.com/ubuntu/ hardy main universe
| |
− | </pre>
| |
− | :now run the following command
| |
− | <pre>
| |
− | sudo apt-get update
| |
− | </pre>
| |
− | :This should pull the hardy ubuntu packages from the repository. You can now run the following commands.
| |
− | <pre>
| |
− | sudo apt-get install gcc-3.4
| |
− | sudo rm /usr/bin/gcc
| |
− | sudo ln -s /usr/bin/gcc-3.4 /usr/bin/gcc
| |
− | </pre>
| |
− | | |
− | * Install the external dependencies as follows
| |
− | <pre>
| |
− | sudo apt-get install libx11-dev libesd0-dev libasound2-dev libzip1 flex
| |
− | </pre>
| |
− | | |
− | * Now move to the 'htk-3.4' dir and configure htk as follows. Note change %yourusername% from the command to your user name.
| |
− | <pre> | |
− | cd htk-3.4
| |
− | ./configure --prefix=/home/%yourusername%/bin/htk-3.4
| |
− | </pre>
| |
− | | |
− | * Now run make all and make install. This should install the created binaries to the folder '/home/yourusername/bin/htk-3.4/bin' .
| |
− | <pre>
| |
− | make all
| |
− | make install
| |
− | </pre>
| |
− | | |
− | * Change directory back to home and create a folder called 'voxforge' and then a folder called 'HTK_scripts' in the voxforge folder.
| |
− | <pre>
| |
− | cd ~
| |
− | mkdir voxforge
| |
− | cd voxforge
| |
− | mkdir HTK_scripts
| |
− | cd HTK_scripts
| |
− | </pre>
| |
− | | |
− | * Now copy some scripts from the 'htk-3.4/samples' folder to the 'HTK_scripts' folder as follows
| |
− | <pre>
| |
− | cp ../../bin/htk-3.4/samples/RMHTK/perl_scripts/mkclscript.prl .
| |
− | cp ../../bin/htk-3.4/samples/HTKTutorial/maketrihed .
| |
− | cp ../../bin/htk-3.4/samples/HTKTutorial/prompts2mlf .
| |
− | cp ../../bin/htk-3.4/samples/HTKTutorial/prompts2wlist .
| |
− | </pre>
| |
− | | |
− | * Your 'HTK_scripts' folder should contain the following
| |
− | <pre>
| |
− | maketrihed mkclscript.prl prompts2mlf prompts2wlist
| |
− | </pre>
| |
− | | |
− | ==== Step 4 ==== | |
− | | |
− | * Now we will download Julius (version 4.5.1). We shall be using pre-compiled binaries which can downloaded from [http://sourceforge.jp/projects/julius/downloads/47530/julius-4.1.5-linuxbin.tar.gz/ here]
| |
− | | |
− | * Once downloaded extract them to your '/home/%yourusername%/bin' folder. After that is done your 'bin' folder should contain the following
| |
− | <pre>
| |
− | htk-3.4 julius-4.1.5-linuxbin
| |
− | </pre>
| |
− | | |
− | ==== Step 5 ====
| |
− | | |
− | * Now you will need to update your user path which can be done as follows. First change to your home directory and edit the .bashrc file.
| |
− | <pre>
| |
− | cd ~
| |
− | gedit .bashrc
| |
| </pre> | | </pre> |
| + | udev runs ''"/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start"'' |
| | | |
− | * Add the following to the end of the .bashrc file. Note change %yourusername% from the command to your username.
| + | Copy ''"/etc/udev/rules.d/99-robotinosr.rules"'' to ''"/etc/udev/rules.d/99-myheadset.rules"'' and modify the new rule to fit your hardware. How to do this can be read [http://wiki.ubuntuusers.de/UDEV here]. |
− | <pre>
| |
− | # HTK and JULIUS scripts and executables
| |
− | PATH=$PATH:$HOME/bin:/home/%yourusename%/bin/htk-3.4/bin:/home/%yourusename%/bin/julius-4.1.5-linuxbin/bin
| |
− | </pre>
| |
| | | |
− | * Source your .bashrc file to reflect the changes
| + | ''"/usr/local/OpenRobotinoAPI/1/daemons/srd.sh"'' uses the ''"/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh"'' to write a valid alsa configuration to ''"/root/.asoundrc"''. The audo interface from which card and device number are taken is given in ''"/etc/robotino/sr/devicename"''. Modify this file to match the output from ''"aplay -l"''. |
− | <pre>
| |
− | source ~/.bashrc
| |
− | </pre>
| |
| | | |
− | * Test if your HTK toolkit has been installed correctly by running the following command.
| + | Test the setup by running ''"/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh"'' and see if ''"/root/.asoundrc"'' is reasonable. Then run ''"/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start"''. If this works test your udev rule by detaching and reattaching your USB audio device and see if srd comes up. |

Speech recognition
Robotino has already been trained for a voice but this may not work for everyone. In case it doesn't, then a new acoustic model will have to be created for that person. There are two ways to do this
- Recommended The acoustic model is created by us and we just need your training data -> Recording data for speech recognition training
- Creating the acoustic model yourself
Setup audio devices
When the Logitech ClearChat headset is plugged into Robotino's USB port, the udev rule "/etc/udev/rules.d/99-robotinosr.rules" matches
SUBSYSTEMS=="usb", KERNEL=="hiddev[0-9]*", SYSFS{idVendor}=="046d", SYSFS{idProduct}=="0a12", RUN+="/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start", SYMLINK+="headset"
udev runs "/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start"
Copy "/etc/udev/rules.d/99-robotinosr.rules" to "/etc/udev/rules.d/99-myheadset.rules" and modify the new rule to fit your hardware. How to do this can be read here.
"/usr/local/OpenRobotinoAPI/1/daemons/srd.sh" uses the "/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh" to write a valid alsa configuration to "/root/.asoundrc". The audo interface from which card and device number are taken is given in "/etc/robotino/sr/devicename". Modify this file to match the output from "aplay -l".
Test the setup by running "/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh" and see if "/root/.asoundrc" is reasonable. Then run "/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start". If this works test your udev rule by detaching and reattaching your USB audio device and see if srd comes up.
