保姆级教程：教你UniMRCP对接华为云ASR（Linux版）
本文分享自华为云社区《unimrcp对接华为云ASR（Linux版）》，作者： ASR-beginer。
本篇文章提供了unimrcp对接华为云ASR的保姆级教程，根据第一到四章，可从头逐步编译+集成基于华为云ASR的unimrcp系统（授人以渔）。同时，本文第五章（直接给条鱼）提供了作者修改好的源码，直接一键编译即可。
一、安装unimrcp
1.提前安装必要的依赖项（系统级）
2.下载unimrcp
3.下载unimrcp的依赖库，并安装
进入https://www.unimrcp.org/downloads/dependencies，直接选择最新版本下载
解压后，进入unimrcp-deps-1.6.0，执行安装命令：
./build-dep-libs.sh
4.安装unimrcp
之后可以在/usr/local/unimrcp 路径下，看到以下内容：
5.ASR测试
先启动服务端./unimrcpserver

二、安装华为ASR SDK
华为ASR C++（Linux版）SDK安装过程参考之前的文章：https://bbs.huaweicloud.com/blogs/392949
这里推荐一键安装，因为本SDK将所有依赖均打包在仓库中，可以在任意Linux机器上编译通过（g++ 4.8.5及以上，cmake版本至少是3.14）
三、unimrcp集成华为ASR SDK
本章节用从底到高的顺序进行记录，即先修改底层代码/配置，再修改顶层代码
1.将（上个步骤 安装华为ASR SDK）编译好的SDK打包起来，并命名为huaweicloud_asr，作为备用，其代码结构如下：
2.进入unimrcp/plugins，调整代码结构，如下图所示
cd umimrcp/plugins mv demo-recog huawei-recog # 将原始的demo-recog重命名成huawei-recog mv huawei-recog/src/demo_recog_engine.c huawei-recog/src/huawei_recog_engine.cc cp -r path_to_sdk/huaweicloud_asr huawei-recog/huaweicloud_asr # 将华为asr sdk拷贝到umimrcp/plugins/huawei-recog/huaweicloud_asr处
3.修改huawei-recog/src/huawei_recog_engine.cc文件，具体内容如下
/** Process START-INPUT-TIMERS request */ static apt_bool_t huawei_recog_channel_timers_start( mrcp_engine_channel_t *channel, mrcp_message_t *request, mrcp_message_t *response) { huawei_recog_channel_t *recog_channel = (huawei_recog_channel_t *)channel->method_obj; recog_channel->timers_started = TRUE; return mrcp_engine_channel_message_send(channel, response); } /** Dispatch MRCP request */ static apt_bool_t huawei_recog_channel_request_dispatch(mrcp_engine_channel_t *channel, mrcp_message_t *request) { apt_bool_t processed = FALSE; mrcp_message_t *response = mrcp_response_create(request, request->pool); switch (request->start_line.method_id) { case RECOGNIZER_SET_PARAMS: break; case RECOGNIZER_GET_PARAMS: break; case RECOGNIZER_DEFINE_GRAMMAR: break; case RECOGNIZER_RECOGNIZE: processed = huawei_recog_channel_recognize(channel, request, response); break; case RECOGNIZER_GET_RESULT: break; case RECOGNIZER_START_INPUT_TIMERS: processed = huawei_recog_channel_timers_start(channel, request, response); break; case RECOGNIZER_STOP: processed = huawei_recog_channel_stop(channel, request, response); break; default: break; } if (processed == FALSE) { /* send asynchronous response for not handled request */ mrcp_engine_channel_message_send(channel, response); } return TRUE; } /** Callback is called from MPF engine context to destroy any additional data associated with audio stream */ static apt_bool_t huawei_recog_stream_destroy(mpf_audio_stream_t *stream) { return TRUE; } /** Callback is called from MPF engine context to perform any action before open */ static apt_bool_t huawei_recog_stream_open(mpf_audio_stream_t *stream, mpf_codec_t *codec) { return TRUE; } /** Callback is called from MPF engine context to perform any action after close */ static apt_bool_t huawei_recog_stream_close(mpf_audio_stream_t *stream) { return TRUE; } /* Raise huawei START-OF-INPUT event */ static apt_bool_t huawei_recog_start_of_input(huawei_recog_channel_t *recog_channel) { /* create START-OF-INPUT event */ mrcp_message_t *message = mrcp_event_create(recog_channel->recog_request, RECOGNIZER_START_OF_INPUT, recog_channel->recog_request->pool); if (!message) { return FALSE; } /* set request state */ message->start_line.request_state = MRCP_REQUEST_STATE_INPROGRESS; /* send asynch event */ return mrcp_engine_channel_message_send(recog_channel->channel, message); } /* Load demo recognition result */ static apt_bool_t huawei_recog_result_load(huawei_recog_channel_t *recog_channel, mrcp_message_t *message) { mrcp_engine_channel_t *channel = recog_channel->channel;

7.添加asr配置文件（进入unimrcp根目录），这些都是必填项，按照备注获取相应的asr鉴权信息：vim conf/asr_info.conf
8.重新编译unimrcp，默认会安装在/usr/local/unimrcp中
./bootstrap make -j make install
9.unimrcp代码结构展示
/usr/local/unimrcp ├── bin # 可执行文件 ├── conf # 配置文件，可以设置访问IP和端口号 ├── data # 默认提供的一些音频文件 ├── include # 程序必须的头文件 ├── lib # 依赖的库文件 ├── log # 日志路径 ├── plugin # 插件所依赖的库文件 └── var # 保存的音频文件

启动客户端：/usr/local/unimrcp/umc，然后在交互窗口执行run recog，获取识别结果
四、unimrcp定制化改动
1. 修改xml文件（在conf文件夹中），指定访问地址和端口号。端口号我们采用默认端口，IP地址指定为本地IP
unimrcpclient.xml修改：
unimrcpserver.xml修改：
2. 利用unimrcp调整ASR断句参数
unimrcp的header里面提供了一组断句参数，来控制响应时间/句子长段（比如，说完一段话之后，等待多少毫秒，给出结果）。各参数名及其含义如下（在路径data/params_default.txt下）
No-Input-Timeout: 5000 -----> 用户接到电话后超过5000ms没有声音，就结束识别 等价于华为云ASR的vad_head Recognition-Timeout: 20000 ------> 用户一直说话，最长能说多久（默认20s），结束识别。等价于华为云ASR的max_seconds Speech-Complete-Timeout: 400 -------> 用户开始说话后，停顿多久(默认400ms)就结束说话
2.1 通过请求参数传递断句参数
以上参数均是通过请求体的header进行传递，参考文档：https://www.unimrcp.org/manuals/html/GoogleSRUsageManual.html
可以通过unimrcp打印的日志，查看参数设置是否生效：
2.2 强制指定断句参数
为了方便管理，建议对所有通话保留相同的断句参数，具体设置如下：
if(recog_header) { if(mrcp_resource_header_property_check(request,RECOGNIZER_HEADER_START_INPUT_TIMERS) == TRUE) { recog_channel->timers_started = recog_header->start_input_timers; } if(mrcp_resource_header_property_check(request,RECOGNIZER_HEADER_NO_INPUT_TIMEOUT) == TRUE) { mpf_activity_detector_noinput_timeout_set(recog_channel->detector,10000); // 强制指定 如果10s中无人说话，就结束 } if(mrcp_resource_header_property_check(request,RECOGNIZER_HEADER_SPEECH_COMPLETE_TIMEOUT) == TRUE) { mpf_activity_detector_silence_timeout_set(recog_channel->detector, 600); // 强制指定600ms } }
3. 利用华为云ASR做智能短句
华为云ASR提供的sentence模式，可适用于外呼、数字人场景，通过设置vad_head/vad_tail/max_seconds参数可以智能短句，相关代码变动如下
if (recog_channel->recog_request) { // 第622行至660行 是unimrcp提供的断句规则，这里禁用中间两个case（因为效果差），直接用华为云的断句规则 // mpf_detector_event_e det_event = mpf_activity_detector_process(recog_channel->detector, frame); // switch (det_event) { // case MPF_DETECTOR_EVENT_ACTIVITY: // apt_log(RECOG_LOG_MARK, // APT_PRIO_INFO, // "Detected Voice Activity " APT_SIDRES_FMT, // MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); // huawei_recog_start_of_input(recog_channel); // break; // case MPF_DETECTOR_EVENT_INACTIVITY: // apt_log(RECOG_LOG_MARK, // APT_PRIO_INFO, // "Detected Voice Inactivity " APT_SIDRES_FMT, // MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); // if (recog_channel->rasr_client) { // recog_channel->rasr_client->SendEnd(); // recog_channel->rasr_client->Close(); // } // finish = true; // huawei_recog_recognition_complete(recog_channel, RECOGNIZER_COMPLETION_CAUSE_SUCCESS); // apt_log(RECOG_LOG_MARK, APT_PRIO_INFO, "get RECOGNIZER_COMPLETION_CAUSE_SUCCESS stop recog"); // break; // case MPF_DETECTOR_EVENT_NOINPUT: // apt_log(RECOG_LOG_MARK, // APT_PRIO_INFO, // "Detected Noinput " APT_SIDRES_FMT, // MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); // if (recog_channel->timers_started == TRUE) { // if (recog_channel->rasr_client) { // recog_channel->rasr_client->SendEnd(); // recog_channel->rasr_client->Close(); // } // huawei_recog_recognition_complete(recog_channel,RECOGNIZER_COMPLETION_CAUSE_NO_INPUT_TIMEOUT); // } // finish = true; // break; // default: // break; // } Status cur_status = recog_channel->call_back->GetStatus(); switch (cur_status) { case Status::voice_start: apt_log(RECOG_LOG_MARK, APT_PRIO_INFO, "Detected Voice Activity " APT_SIDRES_FMT, MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); huawei_recog_start_of_input(recog_channel); recog_channel->call_back->SetStatus(Status::recognizing); break; case Status::voice_end: apt_log(RECOG_LOG_MARK, APT_PRIO_INFO, "Detected Voice Inactivity " APT_SIDRES_FMT, MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); if (recog_channel->rasr_client) { recog_channel->rasr_client->SendEnd(); recog_channel->rasr_client->Close(); } finish = true; huawei_recog_recognition_complete(recog_channel, RECOGNIZER_COMPLETION_CAUSE_SUCCESS); apt_log(RECOG_LOG_MARK, APT_PRIO_INFO, "get RECOGNIZER_COMPLETION_CAUSE_SUCCESS stop recog"); break; case Status::exceeded_silence: apt_log(RECOG_LOG_MARK, APT_PRIO_INFO, "Detected Noinput " APT_SIDRES_FMT, MRCP_MESSAGE_SIDRES(recog_channel->recog_request)); if (recog_channel->timers_started == TRUE) { if (recog_channel->rasr_client) { recog_channel->rasr_client->SendEnd(); recog_channel->rasr_client->Close(); } huawei_recog_recognition_complete(recog_channel,RECOGNIZER_COMPLETION_CAUSE_NO_INPUT_TIMEOUT); } finish = true; break; default: break; }
五、快速搭建unimrcp服务
作者按照前四章逐步执行，并在GitHub和Gitee上发布了修改后的代码，大家可以直接拿来使用。
本代码仓提供两种安装方式供用户选择
方法一： 源码安装
- 先下载安装华为云实时语音识别SDK，安装指南参考https://bbs.huaweicloud.com/blogs/392949
- 将安装的华为云ASR SDK放入plugins/huawei_recog/huaweicloud_asr 】
- 进入根目录/unimcrp-deps-1.6.0，安装安装unimrcp的依赖库
./build-dep-libs.sh
4.进入根目录，安装unimrcp
./bootstrap ./configure make make install
5.unimrcp默认安装在/usr/local/unimrcp中,使用前需要手动修改asr_info.conf中的配置项
方法二：直接使用release库
wget https://gitee.com/computervisionlearner/unimrcp_with_huaweicloud_asr/releases/download/v0.0.1/unimrcp-1.8.0_unimrcp-deps-1.6.0_binary.tar.gz tar -xzvf unimrcp-1.8.0_unimrcp-deps-1.6.0_binary.tar.gz
