Windows Phone 8 How to make SpeechRecognizerUI working better - windows-phone-8

Question

I used SpeechRecognizerUI to read user's voice input. I was expecting to get dollar amount so $200 or $20.32 or $0.43 is an example. However, the response from backend is always like "20 point 32" or "20 dot 32" or "zero point forty five. Is there a better way to use the API samrtly so that I can get "200, 20.32, 0.45"? Thanks!

Answer 1

You could try looking in the alternates, but aside from that, I don't see any way to control text normalization in dictation grammars.

Answer 2

You can load your own grammar to SpeechRecognizer as described here: Adding, loading, and preloading grammars for Windows Phone 8.
In your case will be useful SRGS grammar.
You should create grammar like this (I get this from Microsoft Speech example):
<grammar version="1.0" xml:lang="en-US" mode="voice" root="amount"
xmlns="http://www.w3.org/2001/06/grammar" tag-format="semantics/1.0">
<rule id="amount">
<item repeat="1-3">
<ruleref uri="#number"/>
</item>
<item repeat="0-1">
<ruleref uri="#dot"/>
<item>
<item repeat="0-2">
<ruleref uri="#number"/>
</item>
</rule>
<rule id="dot">
<one-of>
<item> point <tag> out = "." ; </tag> </item>
<item> dot <tag> out = "." ; </tag> </item>
</one-of>
</rule>
<rule id="number">
<one-of>
<item> one <tag> out = 1; </tag> </item>
<item> two <tag> out = 2; </tag> </item>
<item> three <tag> out = 3; </tag> </item>
<item> four <tag> out = 4; </tag> </item>
<item> five <tag> out = 5; </tag> </item>
<item> six <tag> out = 6; </tag> </item>
<item> seven <tag> out = 7; </tag> </item>
<item> eight <tag> out = 8; </tag> </item>
<item> nine <tag> out = 9; </tag> </item>
<item> ten <tag> out = 10; </tag> </item>
</one-of>
</rule>
</grammar>
