Introduction

Liberty Notes Plus works with the Liberty Recorder to create real-time speech-to-text (STT) results. The real-time speech-to-text results can be saved at the end of a hearing session into an rtf file to provide a rough transcript of the proceedings. The results can also be displayed on a large-screen monitor to provide closed-captioning of the courtroom activity.

Liberty Notes Plus also allows the user to create time-stamped bookmark notes that supplement the rough transcript. The text in the resulting rtf file is synchronized with the audio recording file and can be used to cue playback to any point in the recording when used with the Liberty Transcription Assistant.

A convenient search facility allows the user to quickly find text within the resulting rtf file.

Liberty Notes Plus uses third-party speech-to-text processing engines such as Microsoft Azure and requires that the user create an account with such a supplier.
