New computer software that can read lips at almost any angle has helped make sense of one of the Second World War’s lingering mysteries —Hitler’s home movies.
The technology that has allowed the dialogue to be reconstructed is called ALR — automated lip reading — and has been developed by Frank Hubner, a speech recognition expert. The computer recognises the shapes that lips make, turns them into sounds and matches these to a dictionary.
I find these technologies-which I did not know they worked that way- very interesting since we are allowed to know what people say in noisy contexts or in silent films -which is the case-. Of course, these techonogies are subject to errors, but they are quite precise and helpful and the mistakes they make are usually due to very noisy environments or things like that.
