Server的开发进行了介绍下面讲解如何通过配置让FreeSWITCH能够与MRCP

MRCP

unimrcpserver.xml以下xml只展示了需要进行调整的部分将*.so的名称添加到配置文件中enabletrue

!--

/usr/local/freeswitch/conf/mrcp_profiles

vim

valuefalse/--/recogparams/profile

/include3.2.

配置/usr/local/freeswitch/conf/autoload_configs/unimrcp.conf.xml文件

/usr/local/freeswitch/conf/autoload_configs

vim

unimrcp.conf.xml配置文件如下al-unimrcpv2为默认的进行注释下面配置中只配置了xiaoi-mrcp-v2注意该名字与1配置的xiaoi-mrcp-v2.xml中profile

configuration

are:EMERGENCY|ALERT|CRITICAL|ERROR|WARNING|NOTICE|INFO|DEBUG

--param

value3000//settingsprofilesX-PRE-PROCESS

cmdinclude

data../mrcp_profiles/*.xml//profiles/configuration注意完成配置后不能直接

reloadxml

在/usr/local/freeswitch/conf/dialplan/default.xml里新增如下配置

extension

asr.luasession:answer()--freeswitch.consoleLog(INFO,

Called

ivr/ivr-welcome_to_freeswitch.wav

menu

ivr/ivr-this_ivr_will_let_you_test_features.wav

grammar

--session:execute(play_and_detect_speech,menu

detect:unimrcp

{start-input-timersfalse,no-input-timeout

no_input_timeout

session:getVariable(detect_speech_result)

--if

thenfreeswitch.consoleLog(CRIT,Result

nil\n)tryagain

0elsefreeswitch.consoleLog(CRIT,Result

xml

session:hangup()从上面的lua脚本能看出会加载grammar语法文件在/usr/local/freeswitch/grammar目录新增hello.gram语法文件可以为空语法文件须满足语音识别语法规范1.0标准简称

SRGS1.0该语法文件

xmlnshttp://www.w3.org/2001/06/grammar!--

iddigitone-ofitemone/itemitemtwo/item/one-of/rule

/grammar4.

完成以上配置后使用sip软电话拨打配置的号码5001在fs端fs_cli查看log

/result后续开发中使用mod_event_socket的内连模式对fs事件进行监听在play_and_detect_speech

应用执行完成的事件CHANNEL_EXECUTE_COMPLETE中就能获取到语音识别结果。

socket

CHANNEL_EXECUTE_COMPLETE监听事件的结果如下便于查看进行了URL解码省略了该事件的部分细节内容
