miri

Miri is a Raspberry Pi-based personal assistant, controlled by voice, that specialises in answering music-related questions, e.g.

• "Tell me about The Rolling Stones"
• "Play The Knife"
• "What is my next concert?"
• "When did The Beatles break up?"
• "What frequencies can a violin sound?"

Requirements

You will need:

• A Raspberry Pi (running the "soft-float" debian, available from "http://www.raspberrypi.org/downloads")
• USB mic (I used a webcam)

Installation

Install a bunch of stuff:

sudo apt-get install git ncmpcpp mopidy ruby ffmpeg ruby-dev mplayer sox libcurl4-openssl-dev libcurl4-gnutls-dev

and then install Mopidy:

http://docs.mopidy.com/en/latest/installation/raspberrypi/#how-to-for-debian-7-wheezy

checkout the project:

git clone git@github.com:AaronRandall/miri.git

and modify:

miri/lib/miri/app_config.rb

to include API keys for each service. You can sign-up to get API keys from:

• http://www.songkick.com/api_key_requests/new
• https://developer.wolframalpha.com/portal/apisignup.html
• https://developer.echonest.com/account/register

Usage

Run:

bin/miri

Say something! e.g.

• "Tell me about The Rolling Stones"
• "Play The Knife"
• "What is my next concert?"
• "When did The Beatles break up?"
• "What frequencies can a violin sound?"

Other stuff

Run:

bin/miri_with_detection

to allow for detecting audio (e.g. "Hello Miri!"), and automatically start Miri (hands-free, instead of having to manually run bin/miri).
