我从终端呼叫pocketsphinx_continuous，并通过system中的R命令呼叫。我使用完全相同的参数，但是当我在R中运行它时，我得到一个错误，而终端中的那个运行正常。我已经附上了下面的日志，其中我可以看到一些未指明的参数是不同的，例如。 dict，fdict，以及最后的一些评论也有所不同，例如。 Allocating 4101 * 32 bytes (128 KiB) for word entries。
如何解决错误？出现差异的原因是什么？

从第一种情况的登录：

和第二种情况

见145和152（行号）
很明显，您正在运行不同的pocketphinx安装。也许在第一种情况下它来自/usr/bin的pocketphinx失败了，而在第二种情况下它是/usr/local/bin中最近的pocketphinx有效。系统调用并不总是尊重PATH配置。
建议删除旧版本。
