Systems and methods for conversing with a user

A method for determining a character sequence, the method comprising:

• receiving, by way of an input, input speech data originating from a user;
• outputting, by way of an output, output speech or text information;
• obtaining a first list of one or more candidates from first input data received by way of the input;
• comparing one or more entries in the first list with a regular expression, wherein the regular expression specifies a character sequence format;
• if an entry in the first list corresponds to the regular expression:
• selecting a first candidate from the first list, wherein the first candidate corresponds to the regular expression;
• generating a first output based on the selected first candidate, wherein the first output is outputted by way of the output, wherein the first output is a first confirm request to confirm the selected first candidate and wherein, if second input data indicating that die first candidate is not confirmed is received, the method further comprises
• generating a repeat request for the user to repeat the input, wherein the repeat request outputted by way of the output;
• receiving third input data and obtaining a second list of one or more candidates from the third input data;
• comparing one or more entries in the second list with the regular expression;
• if an entry in the second list corresponds to the regular expression:
• selecting a second candidate from the second list, wherein the second candidate corresponds to the regular expression;
• and
• generating a second confirm request to confirm the selected second candidate, wherein the second confirm request is outputted by way of the output.

A non-transitory carrier medium comprising computer readable code configured to cause a computer to perform a method for determining a character sequence, the method comprising:

• receiving, by way of an input, input speech data originating from a user;
• outputting, by way of an output, output speech or text information;
• obtaining a first list of one or more candidates from first input data received by way of the input;
• comparing one or more entries in the first list with a regular expression, wherein the regular expression specifies a character sequence format;
• if an entry in the first list corresponds to the regular expression:
• selecting a first candidate from the first list, wherein the first candidate corresponds to the regular expression;
• generating a first output based on the selected first candidate, wherein the first output is outputted by way of the output, wherein the first output is a first confirm request to confirm the selected first candidate and wherein, if second input data indicating that the first candidate is not confirmed is received, the method further comprises
• generating a repeat request for the user to repeat the input, wherein the repeat request outputted by way of the output;
• receiving third input data and obtaining a second list of one or more candidates from the third input data;
• comparing one or more entries the second list with the regular expression;
• if an entry in the second list corresponds to the regular expression:
• selecting a second candidate from the second list, wherein the second candidate corresponds to the regular expression;
• and
• generating a second confirm request to confirm the selected second candidate, wherein the second confirm request is outputted by way of the output.
