1、超拟人合成：将文字转化为自然流畅的人声，在实时语音合成的基础上，精准模拟人类的副语言现象，如呼吸、叹气、语速变化等，使得语音不仅流畅自然，更富有情感和生命力。
2、唤醒的持久运行--->合成能力加持（唤醒成功后语音答复：主人 我在）--->调用在线或离线听写能力（建议用讯飞在线效果好）--->识别用户说的语音成文字后发给大模型--->建议调用讯飞星火认知大模型--->获取大模型答案后调用语音合成（合成在线离线均可）进行答案输出。这样就顺利实现了用纯语音与大模型进行交互！
3、在获取大模型答案后调用语音合成（合成在线离线均可）进行答案输出环节，讯飞推出超拟人合成，交互更像真人。
4、通过对大模型返回及时性与合成及时性的结合，逻辑编排使得模拟真人交互成为可能。
5、超拟人合成Java调用示例给大家！
