刚刚在我的树莓派上安装了pocketsphinx。认为我快疯了,但不确定我是否提供了正确的设备。
每当我跑步时:
src/programs/pocketsphinx_continuous -adcdev plughw:1,0 -nfft 2048 -samprate 48000
我得到以下信息:

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 将 Raspberrypi 连接到电视并运行 aplay ~/test.wav 来验证这一点)
我做错了什么伙计们?

同样在安装袖珍狮身人面像方面,我做了以下事情:
# uninstall pulse audio if its already installed
apt-get remove pulseaudio -y
aptitude purge pulseaudio -y
# sphinxbase install
apt-get install bison -y
cd /usr/install
wget http://downloads.sourceforge.net/project/cmusphinx/sphinxbase/0.8/sphinxbase-0.8.tar.gz
tar -xvf sphinxbase-0.8.tar.gz
cd sphinxbase-0.8
./configure
make
make install
cd -
# pocketsphinx installwget http://sourceforge.net/projects/cmusphinx/files/pocketsphinx/0.8/pocketsphinx-0.8.tar.gz
tar -xvf pocketsphinx-0.8.tar.gz
cd pocketsphinx-0.8
./configure

make install
任何朝着正确方向的想法或建议都会非常有帮助。
