RaspberryPi + Pocketsphinx + ps3eye错误:无法打开音频设备

Mal*_*nes 10 audio speech-recognition speech-to-text cmusphinx raspberry-pi

刚刚在我的覆盆子pi上安装了pocketsphinx.我觉得我疯了但不确定我是否提供了正确的设备.

每当我跑:

src/programs/pocketsphinx_continuous -adcdev plughw:1,0 -nfft 2048 -samprate 48000

我得到以下内容:

我目前正在使用ps3eye.如果我做一个简单的:

arecord -D plughw:1,0 -d 5 -q -f cd -t wav~/test.wav

一切正常(通过HDMI连接Raspberrypi并运行播放〜/ test.wav验证了这一点)

我做错了什么人？

我花了一些时间,在一些来源的帮助下(他们将在我的答案中列出)和一些来自nikolay-shmyrev的有用提示,我终于想出了一个对我有用的答案.

主要假设:

  1. 以pi用户身份运行这些命令(之前我以root身份运行它们,这是不正确的)

  2. 我正在使用持续识别,我只是在寻找能够"唤醒"我的覆盆子pi.醒来之后,我还有其他应该如何互动的计划.

我的设置:

  1. Canakit RaspberryPi

  2. HDMI线连接到我的东芝电视

  3. usb wifi加密狗

  4. Playstation 3 Eye用于语音识别

向前进.我在RaspberryPi上运行了以下命令,让PulseAudio + pocketsphinx与我的Playstation 3 Eye一起工作.(如果您有任何改进的地方请告诉我)
