Searchable Dataset of Recorded Voicemail & Calls

It would be nice if recorded calls and voicemails can be saved as text, and then made searchable. For example, if I remember talking with a customer about certain issues, I can search up the key word(s), and find the call or voicemail where that word(s) were mentioned. This also allows me to search swear words (if any were used), mention of competition, prices, etc - allows for much better quality control of my company's communication with customers.
