Highly accurate audio search results

Azure Media Indexer automatically makes your media deeply searchable without the need for manually applied metadata. Using deep neural net (DNN)-based speech recognition technology from Microsoft Research, Media Indexer converts digital audio into natural language and automatically extracts meaningful metadata from your media.

Innovative custom vocabulary adaptation

With its custom vocabulary adaptation, Media Indexer consistently outperforms industry-standard speech transcription technology. Indexing medical lecture content? Submit custom words like “aneurysm” alongside your indexing job, and watch as Media Indexer scours the Internet to include related words such as “hemorrhage” or “embolism” to its internal dictionary, dramatically increasing accuracy.

Auto-generated closed captions

Reduce the effort required to make your multimedia accessible by passing your content through Media Indexer. Use the output caption file (in your preferred format) to provide closed captions for your users.

Extract keywords from speech

Media Indexer can generate keywords from speech content in your multimedia and produce an XML file containing the frequency and time offset of each spoken keyword and other valuable data. Use the file to perform speech analytics, tag your content, or power a recommendation engine.
