marcel

a bot which listens and says non sense in several languages

$ npm i
$ npm start linux release

or

$ npm start raspi release

requirements

speak

on a raspberry:

$ sudo apt-get install gcc libasound2 libasound2-dev
$ sudo apt-get install mpg321

vi node_modules/speech-stream/node_modules/mespeak/src/index.js orvi node_modules/mespeak/src/index.js then replace

var ESpeak = require("./ESPEAK.js")

with

var ESpeak = require("./ESpeak.js")

listen

Needs pocketsphinx installed and configured, which is not an easy task.

Specific to raspberry:

• the instructions for raspberry pi
• find the missing file alsa-base.conf (use the comment about /lib/modprobe.d/aliases.conf)
• this post about trouble shooting mic/audio and this one too

My parent folder looks like this

• openfst
• phonetisaurus
• Phonetisaurus
• pocketsphinx
• pocketsphinx-python
• sphinxbase
• marcel

Use this tool to chose words to be recognized (optional but much more efficient)

• http://www.speech.cs.cmu.edu/tools/lmtool-new.html
• also see http://www.speech.cs.cmu.edu/sphinx/models/

Then use npm run listen:sentences in index.js

Here are foreign language packs: http://www.politepix.com/languages

Convert *.lm.dmp to *.lm (very slow) (from this tutorial)

sphinx_lm_convert -i ../fr/fr.lm.dmp -ifmt bin -o ../fr/model.lm -ofmt arpa

Convert to .bin (quicker to start)

sphinx_lm_convert -i model.lm -o model.lm.bin

road map

• activate between "marcel" and "shut up marcel"
• switch between languages
• repeat mode
• record / play sound
• play radio
• give the time, set timer
• search duckduckgo instant answers
