I'm working on an UWP app which should filter cars by their VehicleIdentificationNumber (VIN). This VIN is a 17-char long string. It can include Numbers and letters on every position.
Do anyone has an idea, how i can let the User dictate this 17-char long string and Cortana will understand this correctly? Some tests showed that Cortana understands sometime the digits, and in a second try she writes it out as "three" fe
This are the lines in my VCD-File, which than calls a Background Service. In the BackgroundService the Result i get out of VehicleIdentificationNumber is "...".
<Command Name="selectedSpecificVehicleByVIN">
<Example>Fahrzeug nach VIN WAUZZZ8V5EA012963 filtern</Example>
<ListenFor RequireAppName="BeforeOrAfterPhrase">Fahrzeug nach VIN {VehicleIdentificationNumber} filtern</ListenFor>
<Feedback>Suche nach Fahrzeug mit VIN {VehicleIdentificationNumber}</Feedback>
<VoiceCommandService Target="VehicleSelectionService"/>
</Command>
And my PhraseTopic looks like this:
<PhraseTopic Label="VehicleIdentificationNumber" Scenario="Dictation" />
I have found an answer for this case. It was quite simple. I only had to add two subjects to my PhraseTopic.
<PhraseTopic Label="VehicleIdentificationNumber" Scenario="Dictation">
<Subject>Characters</Subject>
<Subject>Alphabet</Subject>
</PhraseTopic>
One small problem is, that Cortana adds some whitespaces inside the spelled VIN. This can be removed with simple string operations.
Hope I can help somebody, who has the same problem.
I had to write a parser that would take the string response that you are provided and convert the number text to digits. If you're doing one digit at a time, it shouldn't be too bad.
You could also try to create a target for each digit/letter since most people would speak them separately. Then, instead of using a PhraseTopic, use a Phraselist and put each digit and letter in the list.
