An apparatus comprising a session file, session file editor, annotation window, concatenation software and training software. The session file includes one or more audio files and text associated with each audio file segment. The session file editor displays text and provides text selection capability and plays back audio. The annotation window operably associated with the session file editor supports user modification of the selected text, the annotation window saves modified text corresponding to the selected text from the session file editor and audio associated with the modified text. The concatenation software concatenates modified text and audio associated therewith for two or more instances of the selected text. The training software trains a speech user profile using a concatenated file formed by the concatenating software. The session file may have original audio associated with the selected text, wherein the apparatus further comprises software for substituting the modified text for the selected text. In some embodiments, the concatenation software concatenates modified text and audio associated therewith for two or more instances of the selected text. In some embodiments, the training software trains a speech user profile using a concatenated file formed by the concatenating software.
