Travel AI Translator

This repository is a template for anyone wishing to build quickly a web application using the following technologies:

• Flask
• OpenAI Speech-to-text API
• OpenAI GPT API
• Google Text-to-Speech API

You are welcome to inspire and use the code freely for your own projects.

The showcase application, Travel AI Translator, is a multi-language transcription and translation web application. The application allows users to record audio and transcribes the audio into the text of a selected language. Then, it translates the transcribed text into another selected language and returns an audio output of the translated text. This entire process is powered by OpenAI's API, ensuring high accuracy and efficient translation.

Demo

To see the Travel AI Translator in action, please visit the live demo webapp here or download the android app on the Play Store here.

Try recording your own voice and see how efficiently and accurately it transcribes and translates your words. This tool can greatly assist you during your travels or in any cross-language conversation scenario.

Getting Started

Follow the steps below to set up the project locally.

Prerequisites

You need to have Python 3.9 and pip installed on your machine. You can download Python from here: https://www.python.org/downloads/. You also need an API key for OpenAI API.

Installation

1. Clone this repository:

   git clone https://github.com/Daugit/travel-translator.git
   

2. Install the required packages:

   pip install -r requirements.txt
   

3. Configure the OpenAI API Key

   Create a config.ini file at the root of the project. Enter your OpenAI API Key in the following format:

   [OPENAI_API]
   key = <your-key>

   Make sure to replace <your-key> with your actual OpenAI API Key.

4. Generate a self signed certificate

   In order to be able to record audio in a browser, the flask app needs to have SSL certificates.

   Open a Terminal or Command Prompt in this project folder:

   • On Unix-based systems, you can open a terminal.
   • On Windows, you can use git bash

   Generate a Private Key:

   • Execute the following command to generate a private key (key.pem): openssl genrsa -out key.pem 2048 This command creates a 2048-bit RSA private key. You can adjust the bit length for stronger encryption, but 2048 is generally sufficient.
   • Generate a Self-Signed Certificate: Now, generate a self-signed certificate (cert.pem) using the private key: openssl req -new -x509 -key key.pem -out cert.pem -days 365 This command will prompt you to enter various details like country name, state, organization, etc. These details are used to fill in the certificate's subject field.

5. Start the Flask server: In Anaconda Prompt :

   flask --app app.py run --port 5009 --host 0.0.0.0 --cert=cert.pem --key=key.pem
   

6. Navigate to http://localhost:5009 in your web browser.

Confidentiality Rules

We prioritize the privacy and confidentiality of our users. All audio recordings and transcriptions are processed securely using OpenAI's API and Google Text-to-Speech API. While these services ensure high accuracy and efficient translation, we want to assure our users that we do not store, share, or use your audio recordings and translations for any purpose other than to provide you with the service. Both OpenAI and Google have stringent data protection standards, and any data sent to their APIs is used solely for the purpose of transcription and translation. When using our application on the Android Play Store, rest assured that your data remains private and is treated with the utmost care. We are committed to upholding the highest standards of data protection and encourage users to review our privacy policy, as well as those of OpenAI and Google, for further details.
