前端录音生成wav文件后端去解析
后端:
Vosk是一个离线开源语音识别工具。它可以识别16种语言,包括中文。
API接口,让您可以只用几行代码,即可迅速免费调用、体验功能。
目前支持 WAV声音文件格式,支持中英文等18种语言。
前端:
js-audio-recorder 录音组件
springboot整合vosk实现简单的语音识别功能
javaswing窗体
就是录音组件会要求后端使用https协议,生产环境必须将后端http转https,测试环境中有以下两种方法第一种录音只能在(http://localhost:项目端口)中使用,第二种使用谷歌配置网站具有使用录音权限

修改wavFilePath的值为你的wav格式的文件所在路径,wav文件可以自行使用手机自带的录音功能去生成最后点击main方法就可以测试了,如果需要与前台对接请自行修改为接口
