Best Practices

最佳实践

  1. Match voice to content - Professional voice for business, casual for social
  2. Use punctuation - Control pacing with periods and commas
  3. Keep sentences short - Easier to generate and sounds more natural
  4. Test different voices - Same text sounds different across voices
  5. Adjust speed - Slightly slower often sounds more natural
  6. Break long content - Process in chunks for consistency
  1. 语音匹配内容 - 商务内容用专业语音，社交内容用休闲语音
  2. 使用标点符号 - 用句号和逗号控制节奏
  3. 保持短句 - 更易生成且听起来更自然
  4. 测试不同语音 - 同一文本在不同语音下效果不同
  5. 调整语速 - 稍慢的语速通常更自然
  6. 拆分长篇内容 - 分块处理以保证一致性
