Abstract
A method and apparatus records at a first mobile device, separately, each of an upstream component and a downstream component of a speech data associated with users of the first mobile device and a second mobile device in a full-duplex communication system. Speech endpointing is performing on each recorded component to delimit speech chunks in each component using timing information common to both components. The speech chunks are converted to text chunks using at least one automatic speech recognition process and the text chunks are displayed, based on the timing information, in chronological order on a graphical user interface of the first mobile device as diarized text.

A method for speaker diarization, comprising:
- recording at a first mobile device, separately, each of an upstream component and a downstream component of a speech data associated with users of the first mobile device and a second mobile device in a full-duplex communication system;
- performing speech endpointing on each recorded component to delimit speech chunks in each component using timing information common to both components;
- converting the speech chunks to text chunks using at least one automatic speech recognition process;
- displaying, based on the timing information, the text chunks in chronological order on a graphical user interface of the first mobile device as diarized text.
A mobile device, comprising:
- memory operable to record, separately, each of an upstream component and a downstream component of a conversation between users of devices in a full-duplex communication system;
- a speech endpointer configured to delimit speech chunks in each component using timing information common to both components;
- an automatic speech recognizer operable to convert the speech chunks to text chunks using at least one automatic speech recognition process;
- and
- a graphical user interface configured to display, based on the timing information, the text chunks in chronological order a diarized text.
