Piwho

Piwho is python wrapper around MARF speaker recognition framework for the Raspberry pi and other SBCs. With the Piwho you can implement speaker recognition in your projects.

Blink example

import RPi.GPIO as GPIO
import time
from piwho import recognition, vad

def blink(pin):
    GPIO.setmode(GPIO.BOARD)
    GPIO.setup(pin, GPIO.OUT)

    for i in range(0,10):
        GPIO.output(pin,GPIO.HIGH)
        time.sleep(1)
        GPIO.output(pin,GPIO.LOW)
        time.sleep(1)

if __name__ == "__main__":
   recog = recognition.SpeakerRecognizer('./')
   vad.record()
   name = recog.identify_speaker()
   if name[0] == 'Abhishek':
       blink(11)

Tested on

• Ubuntu 15.10
• Pi 1 model B (raspbian wheezy, jessie)
• Pi 2 model B (raspbian wheezy, jessie, stretch)
• CHIP

Installation

Update the Pi

$ sudo apt-get update
$ sudo apt-get upgrade

You need to have JDK (min version: 1.7) installed on your Pi.

# verify jdk is installed
$ java -version

Pyaudio is required to run audio recording script. (Optional)

# Install portaudio
$ sudo apt-get install portaudio19-dev
# Install python dev package
$ sudo apt-get install python2.7-dev
# Install pyaudio
$ pip install pyaudio

Piwho is on PyPI

$ pip install piwho

or clone the project from github

$ git clone https://www.github.com/Adirockzz95/Piwho.git
$ cd Piwho
$ python setup.py install

Tests

Tests are implemented using unittest framework:

$ pip install -r requirements.txt
$ python -m unittest discover -v ./tests

Documentation

• Training the model
• Recognition
• Gender detection
• integrating with Jasper

Tips / Caveats

• Recognition/Training time depends on the length of an audio file.
• If possible overclock your Pi- use Turbo mode.
• Give maxmium RAM to CPU.
• Read MARF manual to know how the it works.
• Recognition speed is directly proportional to the CPU power.

Misc

Here are resources/similar projects I came across while working on this project.

• recognito : Works very well on Pi, but data storage is not implemented.
