申请自己的网站,重庆网络seo公司,数据库用于网站建设哪个好,自己做网站难么阿里提供的demo代码都是javascript#xff0c;自己捏个轮子。参考着自己写了一个阿里巴巴一句话听写Nls的typescript模块。VUE3的组合式API形式
startClient#xff1a;开始听写#xff0c;注意下一步要尽快开启识别和传数据#xff0c;否则6秒后会关闭
startRecognition…阿里提供的demo代码都是javascript自己捏个轮子。参考着自己写了一个阿里巴巴一句话听写Nls的typescript模块。VUE3的组合式API形式
startClient开始听写注意下一步要尽快开启识别和传数据否则6秒后会关闭
startRecognition开始识别事务传入识别回调可以打印字符或显示到屏幕
sendSound发送二进制PCM数据格式16MHz16bit
stopRecognition结束识别事务
