Speech to Text(Intel IoT)

Hi everyone this is a project

how to make intel edison as SpeechRecognition module

Overview:

This project is about making intel Edison Speech recognition system.

This is an module which can use any where in our IoT project

for example: you can use this module in a remote car , you can control the car using your voice instruction.

First of all configure your edison's ALSA configuration

choose your active microphone Intel can connect with microphone in two ways 1. via USB, 2. via Bluetooth.

I used Bluetooth first but I have some issues in my but device so I shifted to USB device.

Hardware Needed for This Experiment:

Intel Edison with extension board

USB sound card

Head set with microphone.

okay lets start hack..

First of all configure your edison's ALSA configuration
choose your active microphone Intel can connect with microphone in two ways 1. via USB, 2. via Bluetooth. I used Bluetooth first but I have some issues in my but device so I shifted to USB device.

Connect your USB sound card to edison

then,

root@edison1:~# lsusb

root@edison1:~# aplay -Ll

root@edison1:~# cat /etc/asound.conf

pcm.!default sysdefault:Headset

test:

root@edison1:~# aplay /usr/share/sounds/alsa/erumbil.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono root@edison1:~#

if you her song you configure right else you should go through these steps again

How to Configure

First of all configure your edison's ALSA configuration
choose your active microphone Intel can connect with microphone in two ways 1. via USB, 2. via Bluetooth. I used Bluetooth first but I have some issues in my but device so I shifted to USB device.

make sure you installed python

install python pip.

using pip install pypi,

install speech_recognition,

instal PyAudio.

Code

Then use this code and execute for speech recognition

import speech_recognition as sr

r = sr.Recognizer() with sr.WavFile("test.wav") as source: # use "test.wav" as the audio source

r.energy_threshold = 4000 audio = r.record(source) # extract audio data from the file

try:

print("You said " + r.recognize(audio)) # recognize speech using Google Speech Recognition except IndexError: # the API key didn't work
