Automatic Speech Recognition in Videos
Automatic speech recognition (ASR) interprets human speech using statistics and recognizes the speech itself as well as keywords, sentences and their meaning. In addition, important security functions (i.e. authorization, access permission) are identified for the speaker.
Understanding Different Speakers with our ASR
Our ASR is outstanding not only because of the vast number of stored words but also because of its ability to learn new words and understand different speakers. Human speech is often inaccurate caused by variations in pronunciation speech flow. The speech recognition system recognizes whole words as well as single sounds (phonemes).
Videos become more and more important when addressing users, especially for e-commerce where users have to be convinced to buy a product. Therefore, it is obvious to optimize videos for search engines, as well. The main requirement for this is to upload videos to the important video hosting platforms and register them directly in search engines, especially Google.
Direct Registration of Videos with Google
The direct registration of the videos, particularly with Google, is a very important step in the video optimization process. For this an individually adapted video sitemap, similar to a normal sitemap, is used. The video sitemap is in XML format and contains important information about the video (most important: title and description). The title may contain a maximum of 100 characters. If the theme of the video is, for example, “painting walls” the sitemap could look like this (all parameters are optional, except for the tags):

Video hosting platforms like YouTube have a tremendous advantage in being able to find and show relevant videos directly. Depending on the platform, higher ranking can be usually achieved through classic SEO techniques, e.g. search terms in the title, tag and description (keywords). Another very important aspect, which is very difficult to influence, is user conduct. It consists of the frequency and number of hits, number and kinds of ratings, number of times watched, frequency of appearance in lists of favorites and playlists as well as number of channel subscriptions and video responses.
