Abstract: Despite the technological improvement and arrival of new methodologies in the different process of a speech-based applications, a parallel development is not observed in the availability of audio-visual speech database. This paper provides a detailed hierarchical picture of the existing audio-visual speech database. Since the performance of a speech-based application deeply depends on the different parameters like the number of speakers, speaker variability, phonetically balanced sentences, recording quality etc. involved in the creation of a database to attain specific task. This paper gave more importance to these parameters involved in the exciting audio-visual speech database rather than the experimental side which need linguistic knowledge about the concerned language in the feature extraction task and classification task. This paper is arranged in such a way that a new face in this realm can capture the needy things to build a speech database in his language. In addition, this paper differs from other review papers in the aspect that it gives equal importance to the available audio-visual speech database in the resourced and under-resourced languages.
Keywords: Audio-Visual Speech Database, Speech-Based Applications, Video Parameters and Audio Parameters.
