5. The computer system of claim 4 , wherein the computer system is further configured to perform at least the following operations: during the transcription stage: dynamically analyzing, by the adaptive self-trained computer engine, at least two adjacent to-be-transcribed speech audio segments of the plurality of to-be-transcribed speech audio segments to determine that the at least two adjacent to-be-transcribed speech audio segments comprise utterances received from a plurality of users when at least one first audio feature of at least one first to-be-transcribed speech audio segment of the at least two adjacent to-be-transcribed speech audio segments, which is representative of to-be-transcribed speech audio data of a first user, differs from at least one second audio feature of at least one second to-be-transcribed speech audio segment of the at least two adjacent to-be-transcribed speech audio segments which is representative of to-be-transcribed speech audio data of a second user.
6. The computer system of claim 5 , wherein the computer system is further configured to perform at least the following operations: during the transcription stage: dynamically identifying, by the adaptive self-trained computer engine, the plurality of users based on the database of digital speaker profiles.
