这篇文章主要为大家详细介绍了微信公众号开发之语音消息识别php代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了php微信语音消息识别代码，供大家参考，具体内容如下

1.开通语音识别(默认关闭)

2.语音识别

请注意，开通语音识别后，用户每次发送语音给公众号时，微信会在推送的语音消息XML数据包中，增加一个Recognition字段(注：由于客户端缓存，开发者开启或者关闭语音识别功能，对新关注者立刻生效，对已关注用户需要24小时生效。开发者可以重新关注此帐号进行测试)。开启语音识别后的语音XML数据包如下：

/**

* wechat php test

*/

//define your token

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();

//$wechatObj->valid();//接口验证

$wechatObj->responseMsg();//调用回复消息方法

class wechatCallbackapiTest

{

public function valid()

{

$echoStr = $_GET["echostr"];

//valid signature , option

if($this->checkSignature()){

echo $echoStr;

exit;

}

}

public function responseMsg()

{

//get post data, May be due to the different environments

$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

//extract post data

if (!empty($postStr)){

/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,

the best way is to check the validity of xml by yourself */

libxml_disable_entity_loader(true);

$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);

$fromUsername = $postObj->FromUserName;

$toUsername = $postObj->ToUserName;

$keyword = trim($postObj->Content);

$time = time();

$msgType = $postObj->MsgType;//消息类型

$event = $postObj->Event;//时间类型，subscribe(订阅)、unsubscribe(取消订阅)

$textTpl = "

%s

0

";

switch($msgType){

case "event":

if($event=="subscribe"){

$contentStr = "Hi,欢迎关注海仙日用百货!"."\n"."回复数字'1',了解店铺地址."."\n"."回复数字'2',了解商品种类.";

}

break;

case "text"://文本消息

switch($keyword){

case "1":

$contentStr = "店铺地址："."\n"."杭州市江干区.";

break;

case "2":

$contentStr = "商品种类:"."\n"."杯子、碗、棉签、水桶、垃圾桶、洗碗巾(刷)、拖把、扫把、"

."衣架、粘钩、牙签、垃圾袋、保鲜袋(膜)、剪刀、水果刀、饭盒等.";

break;

default:

$contentStr = "对不起,你的内容我会稍后回复";

}

break;

case "voice"://语音消息

//语音识别

$recognition = $postObj->Recognition;

$format = $postObj->Format;

$contentStr = "你发送的是语音消息"."\n"."语音格式为:"."\n".$format."\n"."语音内容为:"."\n".$recognition;

break;

}

$msgType = "text";

$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);

echo $resultStr;

}else {

echo "";

exit;

}

}

private function checkSignature()

{

// you must define TOKEN by yourself

if (!defined("TOKEN")) {

throw new Exception('TOKEN is not defined!');

}

$signature = $_GET["signature"];

$timestamp = $_GET["timestamp"];

$nonce = $_GET["nonce"];

$token = TOKEN;

$tmpArr = array($token, $timestamp, $nonce);

// use SORT_STRING rule

sort($tmpArr, SORT_STRING);

$tmpStr = implode( $tmpArr );

$tmpStr = sha1( $tmpStr );

if( $tmpStr == $signature ){

return true;

}else{

return false;

}

}

}

?>
