I've an audio file with me. Say, a speech. How do I extract the text from the audio and store it efficiently in a database?
If the user queries an audio based on the text stored, making use of certain keywords then I must be able to connect the audios in the database with the keyword and get corresponding audio and throw the audio/audios back at the user.

What langauge, framework, and platform (OS) are you wanting to do this on?

You need to tag your platform and language, as minimum.

No problem, but isn't it logical?
Thank you for your clarification.
