Cued Speech uses lipreading with accompanying hand shapes that disambiguate the visemic (consonant) lipshape. Currently, she uses hearing aids and lipreading along with ASL to aid in communication. Cued Speech can be seen as a manual supplement to lipreading. Some deaf people practice as professional lipreaders, for instance in forensic lipreading. Automated lipreading may help in processing noisy or unfamiliar speech. Trainers recognise that lipreading is an inexact art. Forensic speechreading (or forensic lipreading) is the use of speechreading for information or evidential purposes. Additional supports include lipreading and speech therapy. Automated lipreading may contribute to biometric person identification, replacing password-based identification. A number of studies report anomalies of lipreading in populations with distinctive developmental disorders. Occasionally, 'live' lipreading is involved, for example in the Casey Anthony case. In the US, Consuelo Gonzalez is a leading lipreading expert.
