Pocketsphinx "input overrun, read calls are too rare (non-fatal)"

[David Xanatos]

Pocketsphinx running on Raspberry Pi 3, Raspbian Jessie. Pocketsphinx run via command line:

pocketsphinx_continuous -nfft 2048 -inmic yes -samprate 44100

Sphinx runs, but frequently throws:

input overrun, read calls are too rare (non-fatal)

speaking repeatedly into mic the phrase "test one two.......... test one two........"

I get very occasionally output of

that one to the one to one of the one to that one with the one of the who of you who have do that too

While there is definitely a corelation, I need to know how to do two things:

One, verify that the mic input to the system is not being corrupted, too high, too low, etc (I have run alsamixer but... who knows);

Two, train a vocabulary set to improve recognition

Some raw console output listed below, FWIW - hoping someone may recognize something of value.

Thank you very much for your assistance.

I believe the answer given above does not apply to Ras Pi 3. It was true for R Pi 2, but there are numerous examples of PocketSphinx running on Pi 3, a much faster, overclockable device with much more ram. Can anyone on here with experience on the R Pi 3 comment?

Thanks,

Dave
