This directory contains some examples of basic PocketSphinx library usage in C and Python. To compile the C examples, you can build the target examples. If you want to see how it works manually, either use the library directly in-place, for example, with simple.c:

cmake -DBUILD_SHARED_LIBS=OFF .. && make
cc -o simple simple.c -I../include -Iinclude -L. -lpocketsphinx -lm

Or if PocketSphinx is installed:

cc -o simple simple.c $(pkg-config --static --libs --cflags pocketsphinx)

If PocketSphinx has not been installed, you will need to set the POCKETSPHINX_PATH environment variable to run the examples:

POCKETSPHINX_PATH=../model ./simple

The Python scripts, assuming you have installed the pocketsphinx module (see ../README.md "the top-leve README" for instructions), can just be run as-is:

python simple.py spam.wav

Simplest possible example

The examples simple.c and simple.py read an entire audio file (only WAV files are supported) and recognize it as a single, possibly long, utterance.

Segmentation

The example segment.py uses voice activity detection to segment the input stream into speech-like regions.

Live recognition

Finally, the examples live.c and live.py do online segmentation and recognition.
