Number Trainer is an application to learn numbers in different languages: * supported learning languages: English, French, German, Italian, Russian, Spanish, Turkish* numbers can range from zero to 9999999 (ten million minus one)* two learning modes: asking number or asking translation* random numbers, manually entered numbers or entry with voice recognition (if supported by your Android device)* text-to-speech (if supported by your Android device): let your phone read the translated numbers to youTo check if your Android device supports voice recognition / text-to-speech go to: "Menu" -> "Settings" -> "Voice input & output", then: "Voice recognizer settings" and "Text-to-speech setting". I recommend to uncheck "Always using my settings" in "Text-to-speech settings", because Number Trainer will try to use the actual learning language for text-to-speech.
