An electronic e-reader would not help, because you still would not be able to communicate with each other.
An electronic notepad app would only allow you to draw or type what you want to say, it would not help either of you communicate.
A speech-to-text app would not help because it would not translate the words, only convert them to text.
A language translation app however, would allow you and the other person to communicate and understand each other, because it would take your English and translate it to French.
Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a great day!
Stay Brainy!
