讯飞星火认知大模型智能语音交互调用
随着国内外大模型热度的兴起，依托于大模型的智能化，传统的人机交互已经不能满足人们交互的需求。而结合语音和大模型的交互拜托传统互联网获取知识的文字限制，用语音也可以轻松获取想要的知识和思路。
一、大模型智能语音交互调用实现思路
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！
难点：唤醒+听写同时读取麦克风音频的节奏控制
持续语音交互调用大模型效果图：
