我是靠谱客的博主 昏睡航空,最近开发中收集的这篇文章主要介绍科大讯飞语音识别语音合成webAPI调用示例(基于Python),觉得挺不错的,现在分享给大家,希望可以做个参考。

概述

1.在控制台创建应用获取三元组信息

在这里插入图片描述

2.下载示例代码,本地运行一下,然后根据需要改写代码:

#  本demo测试成功运行时所安装的第三方库及其版本如下,您可自行逐一或者复制到一个新的txt文件利用pip一次性安装:
#   cffi==1.12.3
#   gevent==1.4.0
#   greenlet==0.4.15
#   pycparser==2.19

#  webapi 听写服务参考帖子(必看):http://bbs.xfyun.cn/forum.php?mod=viewthread&tid=38947&extra=
#  语音听写流式WebAPI 服务,热词使用方式:登陆开放平台https://www.xfyun.cn/后,找到控制台--我的应用---语音听写(流式)---服务管理--个性化热词,
#  设置热词
#  注意:热词只能在识别的时候会增加热词的识别权重,需要注意的是增加相应词条的识别率,但并不是绝对的,具体效果以您测试为准。
#  语音听写流式WebAPI 服务,方言试用方法:登陆开放平台https://www.xfyun.cn/后,找到控制台--我的应用---语音听写(流式)---服务管理--识别语种列表
#  可添加语种或方言,添加后会显示该方言的参数值
