英特尔爱迪生语音控制 - 如何配置alsa

我想用英特尔爱迪生实现一个语音控制的轮椅。基本上我会说前进，左，右和停止通过连接到爱迪生板的麦克风 声音适配器 。

对于初始原型，我只想将语音识别的输出显示给CLI。

我跟着 这个 在线教程。一切都很好，直到声音配置部分。

接下来是教程中使用的命令的CLI输出。

的lsusb：

root@edison:/home/speech_to_text# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

ALSA-utils的：

root@edison:/home/speech_to_text# opkg install alsa-utils libportaudio2 libasound2 bison espeak alsa-lib-dev alsa-utils-dev alsa-dev python-numpy

aplay :(在这里给出错误）

我该怎么做才能解决这个问题？

好的，解决了。 .asoundrc文件存在一些问题。

用以下内容替换.asoundrc的内容并且它有效。其次 这个 链接来解决它。

pcm.!default {
    type hw
    card 0
}

ctl.!default {
    type hw           
    card 0
}
