I Built an Open-Source Code Snippet Collection

SnipNest is an open-source code snippet collection that provides a structured, easy-to-use, and searchable repository for developers to share and find code snippets.
The idea for SnipNest came from the founder's frustration with the lack of a suitable resource for quick access to frequently used code snippets.
The project utilizes MDX files to store each snippet, including metadata and example usage, making it simple for contributors to add snippets and maintain organization.
Users are encouraged to contribute their own useful snippets, helping SnipNest to grow as a valuable resource for developers.

How To Build a Multilingual Text-to-Audio Converter With Python

In this article, we will build a simple text-to-audio converter app using Python, googletrans API and gTTS for text-to-speech conversion.
The app will enable seamless conversation in the local language of a new country, making it an ideal tool for tourists.
This project has three main components — Translation (googletrans), Text-to-speech (gTTS), and Audio playback (pygame).
The translate_text() function uses the googletrans library for text translation, and takes in text and the target language code.
text_to_audio() function helps convert the text to audio using gTTS and pygame.
This application has many uses, such as helping people explore foreign countries, aiding in language learning, multi-tasking content consumption, and multinational communication.
Pygame can play the audio files, and builds game-related Python applications and software.
Googletrans is a Python binding for the Google Translate API and allows python scripts to integrate a text translation feature into custom apps.
gTTS comes with a pre-defined set of language templates which can be used to convert text to speech easily.
One can add features to the application like an interactive GUI, options for changing pronunciation and pace of the audio.
