    # - comprehensive response with both original and translated text

@app.route('/translate', methods=['POST'])
def translate_text():
    # Standalone translation endpoint

@app.route('/languages', methods=['GET'])
def get_supported_languages():
    # Get list of supported languages

@app.route('/ui-translations/<language>', methods=['GET'])
def get_ui_translations(language):
    # Get UI translations for specific language

4. Enhanced templates/recorder.html

New Features:

• Multi-language interface (English/Arabic)
• RTL support for Arabic
• Translation toggle controls
• Target language selection
• Enhanced visual design
• Keyboard shortcuts

🌐 Multi-Language Support Implementation

UI Translation System

UI_TRANSLATIONS = {
    'en': { /* English translations */ },
    'ar': { /* Arabic translations */ }
}

Dynamic Language Switching

• Client-side language detection
• Server-side translation API
• Real-time UI updates
• RTL text direction support

Translation Workflow

1. Audio Recording → Record with language preferences
2. Transcription → AI-powered speech-to-text
3. Language Detection → Automatic source language identification
4. Translation → Context-aware AI translation
5. Presentation → Side-by-side original and translated text
