A Calculator with speech input and output!

Only in English and German right now, so language of speech recognition and output must be set to English or German in the system settings.
These are the only languages officially tested and supported, but try experimenting with the language settings.

Easy to use:

- Start the app
- Speak into the mic
- Input (for checking) and result is shown
- if you click on the result text, it is spoken to you

FREE Version: contains ads
Full version: no ads

Words and phrases that are understood:

"plus", "and", "minus", "take away", "times", "divided by", "divide", "by", "squared", "square", "cubed", "cube", "to the power of", "to the", "power", "sine of", "cosine of", "sine", "cosine", all numbers and "point"...

So try to say "three thousand four hundred sixty-five point seven eight nine one times five point six times sine of two times 4 power 2" and it will calculate (in the mathematically correct order of course) the result!

If you want the result to be read, click on it.


For Text to speech (TTS) services to function properly, the device must have both the TTS engine and the appropriate language resource files. In some cases, the user must install the appropriate voice language resource files. The users can install TTS voice resources from the system settings at:

Settings, Voice input & output settings, Text-to-speech, Install Voice Data.

    Ideally, it does exactly what I wanted it to do: continually add to my previous result. However, once the numbers get bigger, it stops "hearing properly". For example: 46.25 + 824 = 870.25 that's just great. However, let's add .47 to the 2nd number. N

    I started it up asked some questions and only a few were correct. In fact, the entire voice rec needs to be remade, because when I said "negative two" it said "f*** you=error".
