Quick Example

#include "echo13d.h"

int main() {
    // Initialize ECHO 13D
    echo_config_t config = {0};
    ECHO13D* echo = echo_init(&config);
    
    // Get default voice template
    voice_template_t* voice = get_default_voice_template(echo);
    
    // Create text content
    text_content_t* content = create_text_content("Hello from ECHO 13D!");
    
    // Synthesize speech
    audio_buffer_t* audio = echo_synthesize_speech(echo, content, voice, NULL);
    
    // Open audio device and play
    audio_device_t* device = open_audio_output_device(DEFAULT_DEVICE);
    play_audio(device, audio);
    
    // Clean up
    close_audio_device(device);
