3. The computing device of claim 1 , wherein determining the voice biometric confidence score based on the sample comprises: selecting a voiceprint for authenticating a caller associated with the in-progress telephone call from at least one database based on input provided by the caller, the input comprising one or more of a username or an account number; and using the selected voiceprint in analyzing the sample to determine the voice biometric confidence score.
1. A computing device, comprising: at least one processor; and memory storing computer readable instructions that, when executed by the at least one processor, cause the computing device to: receive a sample associated with an in-progress telephone call, wherein receiving the sample associated with the in-progress telephone call comprises capturing one or more utterances that are responsive to prompts provided by a representative during the in-progress telephone call; determine a voice biometric confidence score based on the sample; determine to route the in-progress telephone call to a first endpoint based on the voice biometric confidence score, wherein determining to route the in-progress telephone call to the first endpoint based on the voice biometric confidence score comprises: based on the voice biometric confidence score falling below a threshold during the in-progress telephone call, providing routing information to the representative, the routing information being configured to cause the representative to transfer the in-progress telephone call to a specialized representative for handling as a potentially illegitimate call; and based on the in-progress telephone call being transferred to the specialized representative, determine to initiate recording and analysis of the in-progress telephone call, wherein a recording of the in-progress telephone call is saved and sampled to create a defensive voiceprint for identifying a caller associated with the in-progress telephone call as an illegitimate caller.
