Translate

This application allows the robot to use a microphone to record a phrase in spanish and then with the help of Google APIs translate it to English.

  • First we need to import the libraries that we are going to use.

    • In this case we are going to use the google cloud apis, and speech recognition.

import argparse
import base64
import httplib2
import os
from google.cloud import translate
import speech_recognition as sr

  • Explaining the code

    • First we need to get the credentials of the json file to storage at "Google_Application_credentials"

    • Then we connect to the vision.googleapis and open a connection.

    • We also use the translate api so we could change the result to spanish, we select spanish at the target.

    • We use speak to tell the user to be prepare to say his phrase.

    • First we calibrate the ambient noise, we record 5 seconds.

    • We start recording when the user start to talk and stop when we detect complete silence.

    • We send the audio to google api, and we recibe the translated audio.

    • We use espeak to tell the original phrase, and then the translated phrase.

    • We use some try and catch to prevent errors of translation.
