This paper proposes a lip reading technique for speech recognition by using motion estimation analysis. The method described in this paper represents a sub-system of the Silent Pass project. Silent Pass is a lip reading password entry system for security applications. It presents a user authentication system based on password lip reading. Motion estimation is done for lip movement image sequenc...

Lip-reading has potential attractive applications in information security, speech recognition, secret communication and so forth. To build an automatic lip-reading system, one key issue is how to locate the lip region, particularly under the changing illumination condition. Empirical studies have shown that the recognition rate of a lipreading system greatly relies on the accuracy of the lip lo...

introduction: the every possible attempt in voice disorders assessment is to gather samples which represent individual s’ actual voice in the daily speech. the researchers have found that voice characteristics in reading a passage are closer to daily speech. making texts has been started since early 20th century. the lack o f suitable text in farsi language makes it difficult to conduct requisi...

The promised dataset was obtained from daily Turkish words and phrases pronounced by various people in videos posted on YouTube. purpose of compiling the to provide a method for detection spoken word recognizing patterns or classifying lip movements with supervised, unsupervised, semi-supervised learning, machine learning algorithms. Most datasets related reading consist recorded camera fixed b...

Lip reading has been proven to improve speech recognition accuracy in adverse environments. Most existing lip reading systems have frontal pose assumption, which makes it very difficult to use in tasks such as video transcription (speech recognition of the audio stream for video indexing and retrieval). In this paper, we propose a new method to compensate the lip pose change by exploiting the g...

The need for an automatic lip-reading system is ever increasing. Infact, today, extraction and reliable analysis of facial movements make up an important part in many multimedia systems such as videoconference, low communication systems, lip-reading systems. In addition, visual information is imperative among people with special needs. We can imagine, for example, a dependent person ordering a ...

Automatic lip reading is one of research being developed lately. Automatic lip reading has been used for various purposes, such as enhancing speech recognition and aid to speech training for the deaf. There are two approaches in lip feature extraction, namely appearance based and shape based. Appearance based approach is usually better, because it provides visual features that cover not only li...
