Jasper: manual installation on Raspbian Wheezy

Posted on 26. 12. 2015 by Knight of Pi

This summary is based on the Jasper installation tutorial from the Jasper Project, just with everything required for getting up Jasper manually with Pocketsphinx as Speech-To-Text Engine(STT) and Phonetisaurus for Text-To-Speech(TTS) conversion on a Raspberry Pi with Raspbian Wheezy.

Jasper on the Raspberry Pi 3 or 2
Matt Curry made a new Image which simplifies installing Jasper on a Raspberry Pi 3 massively. This is explained in the new tutorial Jasper on the Raspberry Pi 3; please use that for the Raspberry Pi 3 (or 2) and this tutorial only for installing Jasper manually on the (outdated) Raspbian Wheezy.

Install Raspbian Wheezy
Download the Raspbian Wheezy disk image from Raspberrypi.org and burn it onto a SD card. Plug the SD card into the Raspberry Pi and boot it.

Install dependencies
Install the Jasper dependencies with

sudo apt-get update
sudo apt-get install -y vim git-core python-dev python-pip bison libasound2-dev libportaudio-dev python-pyaudio \
    espeak subversion autoconf libtool automake gfortran g++

sudo apt-get update

sudo apt-get install -y vim git-core python-dev python-pip bison libasound2-dev libportaudio-dev python-pyaudio \

espeak subversion autoconf libtool automake gfortran g++

Test recording
See if sound output and recording are running with

sudo arecord -f S16_LE -d 20 -r 8000 -D hw:1,0 test.wav

1	sudo arecord -f S16_LE -d 20 -r 8000 -D hw:1,0 test.wav

Play and check the record with

aplay -D hw:0,0 test.wav

1	aplay -D hw:0,0 test.wav

Add environment paths
The environment paths have to be added to the .bashrc. Open it with

sudo nano ~/.bashrc

1	sudo nano ~/.bashrc

and add at the end of the file:

LD_LIBRARY_PATH="/usr/local/lib"
export LD_LIBRARY_PATH
PATH=$PATH:/usr/local/lib/
export PATH

LD_LIBRARY_PATH="/usr/local/lib"

export LD_LIBRARY_PATH

PATH=$PATH:/usr/local/lib/

export PATH

Sound configuration
The following configuration is required:
Open alsa-base.conf with

sudo nano /etc/modprobe.d/alsa-base.conf

1	sudo nano /etc/modprobe.d/alsa-base.conf

then find

options snd-usb-audio index=-2

1	options snd-usb-audio index=-2

and replace it with

options snd-usb-audio index=0

1	options snd-usb-audio index=0

Then, execute

sudo alsa force-reload
sudo reboot

1 2	sudo alsa force-reload sudo reboot

Checkout the ALSA manual for additional information.

Download all Packages
The Pocketsphinx STT engine requires the MIT Language Modeling Toolkit, m2m-aligner, Phonetisaurus and OpenFST. All of these packages have to be downloaded and unzipped:

cd ~

Speech-To-Text Engine Pocketsphinx and CMUCLMTK Installation

cd ~/sphinxbase-0.8/
./configure --enable-fixed && make && sudo make install
cd ~/pocketsphinx-0.8/
./configure && make && sudo make install
cd ~/cmuclmtk/
sudo ./autogen.sh && sudo make && sudo make install

cd ~/sphinxbase-0.8/

./configure --enable-fixed && make && sudo make install

cd ~/pocketsphinx-0.8/

./configure && make && sudo make install

cd ~/cmuclmtk/

sudo ./autogen.sh && sudo make && sudo make install

OpenFST Installation
To install OpenFST, enter the following:

cd ~/openfst-1.3.4/
sudo ./configure --enable-compact-fsts --enable-const-fsts --enable-far --enable-lookahead-fsts --enable-pdt
sudo make install
