简介

在AIUI平台创建应用，下载linux sdk，但是sdk默认内部录音不可用，需要修改录音输入

使用mic录音

注：data_source取值为sdk，仅在Android平台SDK下可用，其他平台只能取值user，通过外部输入音频数据。

AIUI例程修改代码

编译需要ALSA支持，因为mic输入需要

static void mic_start()
{
          
   
    printf("mic_start
");
    int errcode;

    errcode = sr_init(&iat, NULL, SR_MIC, &recnotifier);
    if (errcode)
    {
          
   
        printf("speech recognizer init failed
");
        return;
    }
    iat.write_recorder_data = writeAudioRecord;
    errcode = sr_start_listening(&iat);
    if (errcode)
    {
          
   
        printf("start listen failed %d
", errcode);
    }
}
static void mic_stop()
{
          
   
    printf("mic_stop
");
    int errcode = sr_stop_listening(&iat);
    if (errcode)
    {
          
   
        printf("stop listening failed %d
", errcode);
    }

    IAIUIMessage *msg = IAIUIMessage::create(
        AIUIConstant::CMD_STOP_WRITE,
        0,
        0,
        "data_type=audio");
    agent->sendMessage(msg);
    msg->destroy();

    sr_uninit(&iat);
}
// 写入测试音频
void writeAudio()
{
          
   
    // if (NULL != agent) {
          
   
    //     IAIUIMessage* stopMsg =
    //         IAIUIMessage::create(AIUIConstant::CMD_START_RECORD, 0, 0, "data_type=audio");
    //     agent->sendMessage(stopMsg);
    //     stopMsg->destroy();
    // }
    mic_start();
}

void stopAudio()
{
          
   
    // if (NULL != agent)
    // {
          
   
    //     IAIUIMessage *stMsg = IAIUIMessage::create(AIUIConstant::CMD_STOP_RECORD);
    //     agent->sendMessage(stMsg);
    //     stMsg->destroy();

    //     IAIUIMessage *stopMsg =
    //         IAIUIMessage::create(AIUIConstant::CMD_STOP_SAVE, 0, 0, "data_type=raw_audio");
    //     agent->sendMessage(stopMsg);
    //     stopMsg->destroy();
    // }
    mic_stop();
}

cmakelist.txt 增加speech_recognizer.c linuxrec.c等，增加include_directories，增加target_link_libraries
