性能优化与最佳实践

异步处理优化

# 异步批量处理示例async def batch_tts_generation(messages: list, voice_config: dict): \"\"\"批量生成TTS音频，提高效率\"\"\" tasks = [] for message in messages: communicate = edge_tts.Communicate( text=message, **voice_config ) task = asyncio.create_task(communicate.save(f\"{hash(message)}.mp3\")) tasks.append(task) # 并行执行所有任务 await asyncio.gather(*tasks, return_exceptions=True)# 缓存机制实现class TTSCache: \"\"\"TTS音频缓存管理\"\"\" def __init__(self, cache_dir: str, max_size: int = 100): self.cache_dir = cache_dir self.max_size = max_size self._cache = {} async def get_audio(self, message: str, voice_config: dict) -> bytes: \"\"\"获取缓存音频或生成新音频\"\"\" cache_key = f\"{hash(message)}_{hash(str(voice_config))}\" if cache_key in self._cache: return self._cache[cache_key]  # 生成新音频 communicate = edge_tts.Communicate(message, **voice_config) output_file = os.path.join(self.cache_dir, f\"{cache_key}.mp3\") await communicate.save(output_file) with open(output_file, \"rb\") as f: audio_data = f.read()  # 更新缓存 self._cache[cache_key] = audio_data if len(self._cache) > self.max_size: # LRU缓存淘汰 oldest_key = next(iter(self._cache)) del self._cache[oldest_key]  return audio_data

错误处理与重试机制

# 健壮的TTS服务封装class RobustEdgeTTS: \"\"\"带重试机制的Edge TTS服务\"\"\" def __init__(self, max_retries: int = 3, retry_delay: float = 1.0): self.max_retries = max_retries self.retry_delay = retry_delay async def generate_audio_with_retry(self, message: str, **kwargs) -> bytes: \"\"\"带重试机制的音频生成\"\"\" for attempt in range(self.max_retries): try: communicate = edge_tts.Communicate(message, **kwargs) output_file = f\"temp_{attempt}.mp3\" await communicate.save(output_file) with open(output_file, \"rb\") as f:  return f.read() except Exception as e: if attempt == self.max_retries - 1:  raise _LOGGER.warning(\"TTS生成失败，尝试 %d/%d: %s\", attempt + 1, self.max_retries, e) await asyncio.sleep(self.retry_delay * (attempt + 1))
