Multiplexing interface for the CMU Pocket Sphinx engine


from ..base import DelegateTimerManager

[docs]class SphinxTimerManager(DelegateTimerManager): """ Timer manager for the CMU Pocket Sphinx engine. This class allows running timer functions if the engine is currently processing audio via one of three engine processing methods: - :meth:`process_buffer` - :meth:`process_wave_file` - :meth:`recognise_forever` Timer functions will run whether or not recognition is paused (i.e. in sleep mode). **Note**: long-running timers will block dragonfly from processing what was said, so be careful with how you use them! Audio frames will not normally be dropped because of timers, long-running or otherwise. Normal threads can be used instead of timers if desirable. This is because the main recognition loop is done in Python rather than in C/C++ code, so there are no unusual multi-threading limitations. """
