The conv.utils property provides helper methods for extracting and validating information from the most recent user input during a conversation. These helpers are LLM-powered and return typed objects you can store in conv.state or use in your logic.
These utilities are opt-in and may not be enabled in your workspace. Contact your admin to request access.

​
extract_address

Extract a structured postal address from the latest user turn. Optionally validate against a list of known addresses. 
address = conv.utils.extract_address(country="US")
conv.state.user_address = address
Parameters:
  • addresses: Optional list of Address objects to match against. Street name must be specified for each address.
  • country: Optional country code to filter on (default "US").
Returns:
  • An Address instance with available fields populated. Some fields may be None if not provided.
Raises:
  • ExtractionError if parsing fails.

​
extract_city

Extract a valid city name (and optionally state/country) from the latest user turn. 
city_data = conv.utils.extract_city(states=["CA"], country="US")
conv.state.city = city_data.city
Parameters:
  • city_spellings: Optional list of spelled-out city names to match.
  • states: Optional list of states to filter on.
  • country: Optional country code to filter on (default "US").
Returns:
  • An Address instance where the city field is populated; other fields may be None.
Raises:
  • ExtractionError if parsing fails.

​
Address type

Both utilities return the same Address type: 
@dataclass
class Address:
    street_number: Optional[str]
    street_name: Optional[str]
    city: Optional[str]
    state: Optional[str]
    postcode: Optional[str]
    country: Optional[str]

​
Notes

  • Latency: Each method may take a few seconds to complete due to LLM processing.
  • Validation: Providing allowed values (addresses, city spellings, or states) can improve accuracy.
  • Scope: Operates on the most recent user input, including alternate transcript hypotheses.
