🚀 Usage Examples

Simple Usage

import edge_tts

# AI automatically selects voice and optimizes parameters
result = await edge_tts.speak_intelligently("Hello world!", "output.mp3")
print(f"Voice: {result['voice_used']}")
print(f"Content type: {result['analysis'].content_type.value}")

Advanced Usage

import edge_tts

# Full control with enhanced features
enhanced = edge_tts.EnhancedCommunicate(
    "Welcome [pause:medium] to our [emotion:excited] show!"
)
await enhanced.save("podcast.mp3")

# Access analysis and effects
print(f"Effects: {len(enhanced.effects)}")
print(f"Parameters: {enhanced.get_voice_parameters()}")

Batch Processing
