Grammatical Framework based speech recognition grammars for Estonian, English and potentially many more languages

grammars's Issues

Add support for percentages

See various examples at:

Map place names to coordinates

The current solution of mapping placenames to themselves has several problems

• assumes that the executing app can do geocoding
• assumes that the executing app has knowledge of Estonian, e.g. that 'Tolla' and 'Tõlla' are not spelling variants
• does not handle naming ambiguity within the grammar

There should be at least 2 linearization formats:

• 59.123,24.321 (coordinates)
• Village name, County name (disambiguation in language X)

The downside is that the grammar gets 3 times bigger.

Support numbers up to ~10^12

The Numeral-grammar currently supports numbers up do 999999 (10^6), but this is not enough for some common expressions, e.g. including some world currencies.

Remove support for "null sada"

Allow large numbers to be expressed using fractions

Large numbers are sometimes easier to express using fractions, e.g. it is more natural and shorter to say

kaks ja pool miljonit

or

kaks koma viis miljonit

than

kaks miljonit ja viis sada tuhat

Support optional prefix: kui palju on

as in

kui palju on kaks meetrit jalgades

Often this is more natural to say. Also it might reduce errors (e.g. when using the Action grammar which combines many grammars with similarly sounding sentences).

Support weather queries with Estonian placenames

For example translate

ilmateade Pariisi

to

weather Pariisi, Estonia

This query is supported by both Google Search and WolframAlpha.
(Support nominative singular placenames for the time being.)

Add a script which generates using JSGF and parses with GF

This script could be used in testing to make sure that no unwanted (or avoidable) approximation has occurred during the GF->JSGF conversion.

The script should highlight phrases which are accepted by the JSGF but not by the original GF grammar. We know that approximation happens during JSGF->FSA, but maybe it happens already during GF->JSGF in which case it can probably be avoided by redesigning the grammar.

Proper support for kitchen conversions

Add support for mass <-> volume conversion parametrized by a closed set of substances (sugar, flour, coco powder, corn starch, and buckwheat) or a given density value 0.719 g/ml. E.g.

150 grammi jahu milliliitrites
150 grammi milliliitrites eeldusel et ühes liitris on 12345 grammi

Wrap negative numbers in parentheses

Both Google and WolfraAlpha interpret:

-1^1 = -(1^1)
-1+1 = (-1) + 1

But we probably want

miinus X OP Y

to always stand for

(- X) OP Y

Support mixed time expressions, e.g. "2h 30min in sec"

Example:

how much is two hours and thirty minutes in seconds
convert 2 h 30 min to s
