Text Normalization for Extraction of Date, Currency, and Number
Using Uniphore ASR for Speech to Text Conversion, you can extract date, currency and numbers spoken by the user. The extraction is done by sending an input to the U-Self Serve NLP which has:
Numbers as actual digits
Standardized Date formats
Amount of Money along with currency.
The Inverse Text Normalization (ITN) converts the numbers and dates from word to digits, also inverse normalize the alphanumeric.
Set up a VA in the Unified Communication System with Uniphore ASR for US English.
Set parameter for ITN for this VA/Language (in backend).
Set up Intents with slots for the below example:
Date of birth - Spoken as say - 20th March 1984
Phone number - Spoken as “Nine eight seven six five four three two one zero”
SSN - Last five digits of SSN spoken as “one two three four five”
Amount of Money - Spoken as “500 US Dollars”
When the user speaks the above mentioned input, U-Self Serve accepts the Entity values as Intent Slot values and process the Intent. When the parameter is turned off, normalization does not happen.
