解码后的文本位于 pocketsphinx 输出的什么位置?

解码后的文本位于 pocketsphinx 输出的什么位置?

我想使用 Intel Edison 开发板将 .wav 文件转换为文本。我遵循线程并使用pocketsphinx_continuous-infile命令如线程中建议的那样。这给出了一个很长的 CLI 输出。不确定如何从中提取文本。有人能帮忙吗?

root@edison:/# pocketsphinx_continuous -infile /usr/share/sounds/alsa/Front_Right.wav
INFO: cmd_ln.c(691): Parsing command line:
pocketsphinx_continuous \
        -infile /usr/share/sounds/alsa/Front_Right.wav
