An illustrative method includes receiving, at a processor of a computing device, an audio voice signal of a first call participant during a first call, where the first call is a communication across a communication network. The method further includes determining an identity of the first call participant and determining a speech to text profile associated with the identity of the first call participant, where the speech to text profile includes at least one rule for transcribing a word in the audio voice signal into text. The method further includes generating a text output, where the text output is a transcribed version of a plurality of words identified in the audio voice signal of the first call participant. At least one of the plurality of words identified is identified using the at least one rule.
