- Added ps_endpointer_timestamp_cb_t callback type for external timestamps - Added ps_endpointer_set_timestamp_func() to set external timestamp source - Added ps_endpointer_timestamp() to get current timestamp - Modified internal timestamp handling to use callback when available - Maintains full backward compatibility - existing code works unchanged - Added comprehensive test suite (test_endpointer_timestamp) - Added example program demonstrating the new functionality This addresses issue #352 by allowing applications to provide their own timestamp source (e.g., system time, monotonic clock) to avoid drift between audio clock and system clock. The implementation maintains the audio-based timestamp tracking internally for queue management while using the external source for speech start/end timestamps when provided.
PocketSphinx Examples
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 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.
