18. A method of dialogue tracking for a sound portion corresponding to a video signal in an electronic system carrying an image intended to be displayed to a viewer with an associated plurality of audio signals, each of which is audio signal is carried by a channel corresponding to the intended spatial location of the sound of the audio signal being carried thereby relative to the displayed image, including at least one dialogue and at least one surround channels, the method comprising: receiving and detecting audio characteristics for each of the plurality of audio signals; determining viseme spatial locations as being present in the image which is displayed to the viewer; and determining dialogue tracking based on the intended spatial location(s) of sound corresponding to the identified audio characteristics for the plurality of audio signals and the determined viseme spatial locations being present in the displayed image including determining a count of phonemes in a time window for at least one of the plurality of audio signals and analyzing said count of phonemes and performing an action consisting of one or more of a report, an alarm or a correction when an insufficient number of phonemes is less than a threshold and/or an excessive number of phonemes is greater than a threshold are counted in the time window.
