Description
Arvutaja (= the Estonian word for "the one that computes") is a voice actions app, i.e. it converts a spoken utterance in some natural language to an expression/command in some formal language and then evaluates the formal expression.

Currently supported input languages:

- Estonian
- English

Currently supported expressions and commands:

- measurement unit conversion expression
- currency conversion expression
- arithmetical expression
- alarm clock / timer setting command
- phone number
- Estonian address query (only with Estonian language input)

The expressions/commands are evaluated using an external app, such as

- Google Maps
- Google Search website
- WolframAlpha website
- device's built-in alarm clock app
- device's built-in phone app

The arithmetical and measurement unit conversion expressions are also evaluated by Arvutaja itself.

Arvutaja uses grammar-based speech recognition, i.e. its input languages and commands are explicitly defined by a grammar. The grammars are written using Grammatical Framework (GF). For more information, see the separate Grammars-project at http://kaljurand.github.io/Grammars/ (Arvutaja uses the Action-grammar.)

Arvutaja prompts you to first install the speech recognition app Kõnele, see https://play.google.com/store/apps/details?id=ee.ioc.phon.android.speak

Kõnele uses the speech recognition server http://bark.phon.ioc.ee/speech-api/ which has support for grammar-based speech recognition. Note that you can override in the Kõnele settings which grammar is used in Arvutaja, this allows you to use your own grammar with custom voice commands with Arvutaja.
