This application allows users to translate text or uploaded files (TXT, PDF, CSV, Excel) into multiple languages, convert the translated text to speech, and download the resulting audio. It leverages Google's Gemini API for translation and gTTS for speech synthesis.

• Translate free text or uploaded files (TXT, PDF, CSV, Excel)
• Convert translated text to speech (audio)
• Download the audio file
• Supports multiple languages
