Conversational interface determining lexical personality score for response generation with synonym replacement
The present disclosure involves systems, software, and computer implemented methods for personalizing interactions within a conversational interface based on an input context. One example system performs operations including receiving a conversational input received via a conversational interface. The conversational input is analyzed to determine an intent and lexical personality score based on the input's characteristics. A set of responsive content is determined and includes a set of initial tokens representing an initial response. A set of synonym tokens associated with at least some of the initial tokens are identified, and at least one synonym token associated with a similar lexical personality score to the input is determined. At least one of the initial tokens are replaced with the determined synonym token to generate a modified version of the set of response content. The modified version of the response is then transmitted to a device in response to the input.

7. The system of claim 6 , wherein determining the at least one synonym token associated with the lexical personality score similar to the determined lexical personality score of the received conversational input further includes determining at least one synonym token associated with the determined accent.
8. The system of claim 5 , wherein the determined lexical personality score of the received conversational input comprises a third score representing a verbal tone of a speaker associated with the verbal statement.
9. The system of claim 8 , wherein determining the at least one synonym token associated with the lexical personality score similar to the determined lexical personality score of the received conversational input further includes determining at least one synonym token associated with the determined verbal tone of the speaker.
10. The system of claim 1 , wherein each token in the set of initial tokens representing the initial response to the received conversational input comprises a particular phrase within a responsive sentence represented by the set of response content, and wherein each of the identified set of synonym tokens comprises a phrase having a similar meaning to at least one of the particular phrases in the responsive sentence.
11. A non-transitory, computer-readable medium storing computer-readable instructions executable by a computer and configured to:
receive, via a communications module, a first signal including a conversational input received via interactions with a conversational interface;
analyze the received conversational input via a natural language processing engine to determine an intent of the received conversational input and a lexical personality score of the received conversational input, the determined intent and the determined lexical personality score based on characteristics included within the received conversational input, wherein the determined lexical personality score includes at least a first score representing a formality score and a second score representing a politeness score of the received conversational input, wherein the formality score and the politeness score represent respective measures determined based on the characteristics included within the received conversational input;
determine a set of response content responsive to the determined intent of the received conversational input, the determined set of response content including a set of initial tokens representing an initial response to the received conversational input, wherein the initial response to the received conversational input corresponds to a default lexical personality score;
identify a set of synonym tokens associated with at least some of the set of initial tokens, wherein each of the set of synonym tokens are associated with at least a corresponding formality score and a politeness score;
determine, from the identified set of synonym tokens, at least one synonym token associated with a lexical personality score similar to the determined formality score and politeness score of the received conversational input
replace at least one token from the set of initial tokens included in the determined set of response content with the at least one determined synonym token corresponding to the determined formality score and politeness score of the received conversational input to generate a modified version of the set of response content; and
transmit, in response to the received first signal and via the communications module, a second signal including the modified version of the set of response content to a device associated with the received conversational input.
12. The computer-readable medium of claim 11 , wherein the received conversational input comprises textual input received via the conversational interface.
