11. An electronic signature system comprising: a document repository storing (a) a document comprising a plurality of document terms, (b) an audio recording corresponding to at least a portion of the document terms, and (c) metadata that defines an electronic signature status of the document; a memory device; and a processor that is operatively coupled to the memory device, wherein the processor is configured to execute instructions stored in the memory device that, when executed, cause the processor to carry out an electronic signature process, the process comprising: receiving, from a document originator, instructions to invoke an electronic signature workflow that calls for the document to be distributed to a document recipient, establishing a communication session between the electronic signature system and the document recipient, wherein the communication session enables two-way audio communication between the electronic signature system and the document recipient, sending, from the electronic signature system to the document recipient, via the communication session, the audio recording corresponding to at least the portion of the document terms, sending, to the document recipient, via the communication session, a request for a spoken assent to the document terms associated with the audio recording, prompting the document recipient with an audible request to provide the spoken assent, receiving, by the electronic signature system, the spoken assent from the document recipient, wherein the spoken assent is received via the communication session, comparing a voiceprint of the spoken assent with a voiceprint of an authorized document signer, saving the spoken assent in the document repository, modifying the metadata to establish a logical connection between the document and the spoken assent that is saved in the document repository, wherein the metadata is modified only if the voiceprint of the spoken assent substantially matches the voiceprint of the authorized document signer, and sending, to the document originator, at least one of (a) a modified version of the document that is annotated with an indication of the spoken assent, and (b) the spoken assent.
