+ (description "\
+This package provides a speech recognition toolkit based on @code{kaldi}. It
+supports more than 20 languages and dialects - English, Indian English,
+German, French, Spanish, Portuguese, Chinese, Russian, Turkish, Vietnamese,
+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.")
