forward-mode differentiation, and the two can be composed arbitrarily.  The
main intended application of Autograd is gradient-based optimization.")

Italian, Dutch, Catalan, Arabic, Greek, Farsi, Filipino, Ukrainian, Kazakh,
Swedish, Japanese, Esperanto, Hindi, Czech, Polish. The program works offline,
even on lightweight devices.  Portable per-language models are about 50Mb each,
and there are much bigger and precise models available.

Vosk API provides a streaming API allowing to use it `on-the-fly' and bindings
for different programming languages.  It allows quick reconfiguration of
vocabulary for better accuracy, and supports speaker identification beside
simple speech recognition.")
