Editor to share with you how to use .net code to achieve speech recognition in the development of Wechat public platform. I hope you will gain something after reading this article. Let's discuss it together.

Voice recognition is an advanced function and can only be realized after Wechat's real name verification. The authentication fee is 300 yuan / year. If you, as a developer, can apply for a test account, it is also possible. First create a Wechat message class, this analogy has an additional attribute.

Class wxmessage {public string FromUserName {get; set;} public string ToUserName {get; set;} public string MsgType {get; set;} public string EventName {get; set;} public string Content {get; set;} public string Recognition {get; set;} public string EventKey {get; set;}}

Speech recognition is a built-in feature of Wechat, which is very powerful and does not require us to do too much:

Protected void Page_Load (object sender, EventArgs e) {wxmessage wx = GetWxMessage (); string res = ""; if (! string.IsNullOrEmpty (wx.EventName) & & wx.EventName.Trim () = "subscribe") {/ / the welcome word string content = "; content =" /: rose welcomes Beijing Yongjie Youxin Technology Co., Ltd. /: rose\ nreply "Hello" directly. Res = sendTextMessage (wx, content);} else {if (wx.MsgType = = "text" & & wx.Content = = "Hello") {res = sendTextMessage (wx, "Hello, welcome to the public Wechat platform of Beijing Yongjie Youxin Technology Co., Ltd.") } else if (wx.MsgType = = "voice") / / recognize that the message type is speech {res = sendTextMessage (wx, wx.Recognition); / / wx.Recognition is the result of speech recognition. We quote it directly and OK it with text feedback} else {res = sendTextMessage (wx, "Hello, failed to recognize the message!") } Response.Write (res);} private wxmessage GetWxMessage () {wxmessage wx = new wxmessage (); StreamReader str = new StreamReader (Request.InputStream, System.Text.Encoding.UTF8); XmlDocument xml = new XmlDocument (); xml.Load (str); wx.ToUserName = xml.SelectSingleNode ("xml"). SelectSingleNode ("ToUserName"). InnerText; wx.FromUserName = xml.SelectSingleNode ("xml"). SelectSingleNode ("FromUserName"). InnerText Wx.MsgType = xml.SelectSingleNode ("xml"). SelectSingleNode ("MsgType"). InnerText; if (wx.MsgType.Trim () = = "text") {wx.Content = xml.SelectSingleNode ("xml"). SelectSingleNode ("Content"). InnerText;} if (wx.MsgType.Trim () = = "event") {wx.EventName = xml.SelectSingleNode ("xml"). SelectSingleNode ("Event"). InnerText } if (wx.MsgType.Trim () = = "voice") / / if it is a voice message, assign the recognition result to the corresponding attribute Recognition {wx.Recognition = xml.SelectSingleNode ("xml"). SelectSingleNode ("Recognition"). InnerText;} return wx of the entity class. } / send text messages / content / private string sendTextMessage (wxmessage wx, string content) {string res = string.Format (@ ", wx.FromUserName, wx.ToUserName, DateTime.Now, content); return res } after reading this article, I believe you have a certain understanding of "how to use .net code to achieve speech recognition in the development of Wechat public platform".
