Custom Speech Model documentation incorrect vs image on Microsoft website

Question

Azure Speech Support,

The image showing the order the custom ITN is applied is different than the text explanation below.

https://learn.microsoft.com/en-us/azure/ai-services/speech-service/how-to-custom-speech-display-text-format

The image show lexical -> Custom ITN -> Microsoft Default ITN -> Capitalization -> Profanity -> Custom Profanity -> Rewrite

The text below the image says:

Microsoft Default ITN -> Custom ITN which is opposite

Questions:

1. Which order are the rules applied?
2. Also, what is the order of when the Custom Pronunciation and/or the Structured Text Phonetic is applied?
3. If there are multiple Custom ITN rules that would apply, does only one get applied?
4. If allowing multiple Custom ITN rules to a phrase, is the order of how they applied the same as in the text file (see example below)

Example:

(\d(\d)?(\d)?(\d)?)(.(\d(\d)?(\d)?(\d)?))?({ to >-}|{ through >-})(\d(\d)?(\d)?(\d)?)(.(\d(\d)?(\d)?(\d)?))?({percent>%}|{centimeters squared> cm2}|{cubic centimeters> cm3}|{centimeters> cm}|{centimeter squared> cm2}|{cubic centimeter> cm3}|{centimeter> cm}|{cubic meters> m3}|{meters> m}|{meter> m}|{millimeters squared> mm2}|{cubic millimeters> mm3}|{millimeters> mm}|{millimeter> mm}|{milliliters> mL}|{milliliter> mL})

It would be cleaner to have this as 3 different statements but when testing:

'The tumor is fifteen point five to twenty point two millimeters'

it appears only one gets applied when testing.

(\d(\d)?(\d)?(\d)?)(.(\d(\d)?(\d)?(\d)?))?({ to >-}|{ through >-})

({ to >-}|{ through >-})(\d(\d)?(\d)?(\d)?)(.(\d(\d)?(\d)?(\d)?))

({percent>%}|{centimeters squared> cm2}|{cubic centimeters> cm3}|{centimeters> cm}|{centimeter squared> cm2}|{cubic centimeter> cm3}|{centimeter> cm}|{cubic meters> m3}|{meters> m}|{meter> m}|{millimeters squared> mm2}|{cubic millimeters> mm3}|{millimeters> mm}|{millimeter> mm}|{milliliters> mL}|{milliliter> mL})

Answer 1

@Dave Revell Apologies for the late reply.

.

In this documentation, as you rightly pointed out the image is correct and the text is wrong, in that custom ITN applies before default ITN.

I also believe our Product Owners are discussing this issue with you internally over email.

.

I have asked the Product Owners to update the documentation accordingly.

Hope this answers.
